Download the program to find duplicates. Finding duplicate files using Total Commander

A program for finding duplicate files is most often needed by users who store on disk a large number of music, photos and documents.

And, although you can delete such unnecessary copies manually, specialized applications can save a lot of time.

Especially if the files are located in different folders or in .

You can search for such duplicates using the universal software or designed for a specific data type.

In the first case, the search speed increases, in the second, the probability of finding all copies increases.

Universal Applications

Universal applications for finding copies mainly work on the principle of comparing file sizes.

And, since the probability of the same number of bytes in different photos is practically zero, identical values ​​are considered a sign of a duplicate.

Sometimes the algorithm provides for checking names - also an important parameter for the search, especially since the same data in most cases also matches by name.

The advantages of the programs are the ability to find files of any type with their help and the relatively high speed of operation. Disadvantage: lower detection accuracy.

So, for example, none of these utilities will consider the same file saved with different resolutions to be a duplicate.

1. DupKiller

And among its advantages we can note:

  • ease of setup;
  • setting multiple search criteria;
  • the ability to ignore some files (with a certain size or creation date, as well as system or hidden ones).

Important: If files with a size of zero are detected, they do not have to be deleted. Sometimes this may be information created on another operating system (for example, Linux).

Rice. 4. CCleaner system optimization program can also search for duplicate files.

5.AllDup

Among the advantages of another program, AllDup, we can note support for any modern operating system Windows – from XP to 10.

At the same time, the search is also carried out inside hidden folders, and even in the archives.

Although the comparison of information by default occurs by file names, so it is advisable to change the settings immediately.

But during the search process, each duplicate found can be viewed without closing the application.

And if a copy is found, you can not only delete it, but also rename it or move it to another location.

Additional benefits of the application include completely free work for any period of time.

In addition, the manufacturer also produces a portable version in order to search for copies on those computers on which the installation of third-party software is prohibited (for example, on a work PC).

6. DupeGuru

One more useful application The one that searches for duplicates with any extension is DupeGuru.

Its only drawback is the lack of new versions for Windows (although updates for MacOS appear regularly).

However, even a relatively outdated utility copes well with its tasks when working in newer operating systems.

With its help, even system files are easily detected, and the menu is intuitive and in Russian.

Rice. 6. Detecting copies using the DupeGuru utility.

It is noteworthy that, in addition to the usual universal option, the manufacturing company has created a utility for searching for files of a certain type.

There is a separate version for images and another for music.

And, if necessary, clean your computer not only of documents and system files(which, by the way, need to be deleted very carefully - sometimes it’s even worth leaving an “extra” copy rather than disrupting the system’s functionality), it’s worth downloading these applications as well.

7. Duplicate Cleaner Free

Duplicate Cleaner Free, a utility for detecting copies of any file, has the following features:

  • filtering data by extension;
  • Russian interface language;
  • possibility of free use;
  • high speed.

Its disadvantages include minor limitations when searching for images (for this it is recommended to purchase a paid version) and not entirely accurate translation of individual menu elements.

However, due to its effectiveness and ease of use, the application enjoys some popularity.

Finding duplicate audio files

If the search results for duplicates are not satisfactory for the user, you can consider an option designed for specific files. For example, for accumulated on disk.

This need often arises when downloading several albums and collections of the same artist at once - often the same tracks end up in different folders.

They can have similar sizes and differ, by and large, only in names. Especially for this, there are utilities for searching for similar melodies.

8.Music Duplicate Remover

Among the features of the Music Duplicate Remover program are relatively fast search and good efficiency.

In fact, this application “listens” to the composition and compares it with other audio files.

At the same time, naturally, its operating time is longer than that of universal utilities.

However, the amount of data checked by the program is usually tens of times less, so the average scan duration rarely exceeds a couple of hours.

Finding copies of photos and other images

Just as often, the user may need to remove duplicate images.

Especially if there are several collections of personal photographs on your hard drive, sorted by date or location of shooting.

With the help of special software, unnecessary photos and pictures will be detected and destroyed, and there will be more space on (and other storage).

11. DupeGuru Picture Edition

The application for searching for identical pictures is another version of the DupeGuru utility, which can also (and is even desirable) to be downloaded even if there is a universal version.

At the same time, photo analysis also takes longer compared to searching for files of any extension, but the result is worth it.

Images are detected even when there are several duplicates of the same image on the disk, but with different resolutions and, accordingly, sizes.

In addition, to increase efficiency, files with any graphic extensions are scanned - from to .png.

12. ImageDupeless

Moreover, it is distributed free of charge and has a Russian interface. And the manufacturer periodically releases updates to it, increasing the efficiency of image search.

13. Image Comparer

Especially if the user constantly downloads various information from the network.

Using utilities that detect duplicates, you can save more than one hour of your time and several gigabytes of disk space.

In this material we will talk about tools for identifying duplicate photos. In particular, today our review will include six programs for finding duplicate photos on a computer under Windows control. We will compare and choose the best and fastest among them.

Finding identical photos: programs and their comparison

There may be several reasons for the demand for programs for searching identical photos on a computer, for example:

  • Your collection may have grown so large that duplicates are already taking up a lot of space;
  • You need a tool that will find the same or similar photos, saving you the trouble of viewing these images yourself.

In our selection there was room for six interesting programs, four of which are distributed free of charge. Below we are:

  1. We’ll tell you about each of these search programs and help you quickly navigate their interface;
  2. Let's compare all the programs, in which we'll see how they cope with searching for identical images when they are slightly modified;
  3. Let's check how well the programs can cope with a large set of photos weighing several gigabytes.

Find duplicate photos with Image Comparer

The first program in our review that searches for duplicate photos is called Image Comparer. Her strengths: good functionality and interface translated into Russian, including detailed help information.

Now about the disadvantages. First, the program is not free. However, the cost of a license is a humane 350 rubles (although for some reason the number on the website is 500). In addition, you can use Image Comparer for free for the first 30 days.

The second negative point is that it is slightly confusing, which can confuse an inexperienced user. For example, in order to search within one folder (which may contain others), you need to click on the “create gallery” button and select the desired directory in which to scan.

Next, you will immediately be prompted to give a name and save the file of the gallery being created to any convenient location (the program itself will need this file). Once this is done, a list of all the images in the specified folder and its subfolders will open in front of you in the form of a list or thumbnails:

Buttons marked with arrows start a search for duplicates. The first button is a search within one gallery (the folder you selected), the second button a little to the right is within several galleries. We went with the first option.

Next, the program suggested creating another service file in which the results will be saved for further convenient access to them. Actually, creating a file for the gallery and this file with search results can be a little confusing for an inexperienced user. However, then everything is already simple. The found duplicates will appear in front of you:

You can view them in the form of thumbnails, or by clicking on the “image pairs” tab, go to the view where the photos will be compared with each other:

The center slider allows you to adjust the threshold of image similarity. Set it to 100% and you will only have a list of identical pictures that are perfectly similar to each other. Lower values ​​will only show similar photos.

In the settings you can see a huge list of formats from basic JPG and PNG to more exotic ones that the program works with. Formats can be added and excluded from the search. You can also configure the accounting of reflected and inverted images.

Finding identical photos in three clicks with VisiPics

The next program is VisiPics. Unlike the Image Comparer discussed above, VisiPics is free application, also specializing in photo duplicates. Alas, there is no localization into Russian here, but you definitely shouldn’t be upset about this: everything is very simple and extremely clear.

Using the side navigation bar (we've outlined it in a frame), select the desired directory. Next, click the arrow with the “+” sign to add this folder to the list that will be searched. If you wish, you can select several more folders in the same way. Finally, as a third step, click the Play button to start the process of finding duplicates.

To the right of it is a special slider where you can adjust the level of “attention” of the program. With the default baseline, VisiPics found only two groups of duplicates for us, one of which consisted of three images and the other of two:

These are the images that the program considers to be almost identical duplicates. However, if you lower the slider to the Loose level, then there will be simply similar friend to another image. In our case, when installing Loose instead of Basic, the application found four more (5 in the final test below) groups of duplicates, and added one more picture to one of the two already found:

The program has relatively few additional options. Here you can configure search in subfolders (it is enabled by default), display of hidden folders, and take into account photos rotated by 90 degrees. On the loader tab, you can ask VisiPics to ignore small files or, conversely, pictures that are too large high resolution. The latter is important for speed.

Awesome Duplicate Photo Finder

If you are looking for the utmost a simple program for a high-quality search for duplicate photos and images that would be easy to understand, then pay attention to Awesome Duplicate Photo Finder. The interface is in English, but it is so simple that anyone can understand it.

Using the “+” button, specify the directory or several directories you need to search, then click Start Search and the search will begin. The Scan Subdirectories option is enabled by default and is responsible for searching subfolders. The program copes with its tasks, finding both very similar:

And here are pictures that are slightly more different from each other:

In the program settings, you can set the match to 100% if you only need absolutely identical photos.

As you can see, there are few settings. Perhaps the saddest thing is that the program works with only five main formats: BMP, JPG, PNG, GIF and TIFF. Moreover, the latter is not taken into account by default.

There are also options to ensure that duplicates are deleted directly to the Trash and to disable the pop-up confirmation. The program can also update itself automatically.

    Official site ;
  • English language;
  • Distribution: free.

The Similar Images Finder application greets us with an unkind message in English that we need to pay $34 for it. However, the program is ready to work for free for 30 days. Next, a window appears asking you to select directories to search for duplicates:

From it we learn that Similar Images Finder supports 29 image formats, and the user can select specific formats to search or exclude unnecessary ones. In the list, among other things, you can see ico and wbmp.

When you click Next you will start searching for duplicates, and when it is finished, click Next again to see additional settings. By adjusting these, you can more carefully customize what appears in the results list. Finally, by clicking Next a third time, you will see the result itself:

You can move to the next found picture by clicking the miniature arrow in the upper right corner. The entire list of found duplicates opens by clicking on the large button at the top with the addresses of the current files.

In turn, clicking the Next button at the bottom will lead to the final stage of work. There the program will display a list of what, in its opinion, are definitely duplicates and offer to delete them. In the screenshot above, Similar Images Finder coped with an image where a watermark was added and the histogram contrast was changed.

Distinguishing between the pictures, the program calculated at the level of 5.5%. Moreover, in another example, where we added a strong blur effect to the second picture, the differences, according to the application version, for some reason amounted to only 1.2%:

Alas, the program, while finding real duplicates, by default also shows many images that are completely different from each other, as if they have something in common:

Universal search for duplicates with Duplicate Remover Free

Duplicate Remover Free is the only program in our review that is not focused specifically on duplicate photos, but on finding duplicates in general.

As practice shows, such universal solutions do not perform very well in problems related to some narrower area.

However, today we are giving one such program a chance. As the word Free suggests, it is distributed free of charge. The second advantage of the application is the Russian language, and the third is its relative modernity compared to other programs in this collection, many of which, unfortunately, have not been updated for many years.

You should click on the “add directory” button and select the desired folders. By default, the program did not find anything for us in the given directory, however, when at the top instead of “exact duplicates” we selected the “similar images” item, four groups of duplicates were immediately found, one of which consisted of three files at once:

The application has very few additional features. In particular, you can exclude files from the search before and after a certain size.

  • Duplicate Remover Free. Official site ;
  • Russian language;
  • Distribution: free.

Search for matching photos using various algorithms with AntiDupl

The final participant in our review, the AntiDupl program, may appeal to you for several reasons. First of all, it's free. Secondly, it has a Russian interface. The latter, however, is not obvious. In order to enable Russian, open the View menu and in the Language section select the appropriate item:

Unlike others, this program is not installed, but is located in a self-extracting archive, which extracts it along with the necessary files into a separate folder.

To prepare the search for duplicates, click on the button labeled Open and add the necessary directories in the window that appears:

Next, you can click OK, and then activate the green “start search” button on the toolbar. Using a basic algorithm, the program found several groups of duplicates for us:

Having switched the algorithm at the top to the more free SSIM, we already received two more groups of duplicates, and after increasing the “freedom” of the search from 20 to 35%, the program gave us an even more detailed list:

Moreover, in all cases, there were indeed images that were at least noticeably similar to each other. So don't hesitate to experiment with the settings.

The program has many additional options:

On the “search” tab you can find out that AntiDupl supports 13 formats, including, in addition to traditional JPG/PNG, ICON, PSD and EXIF. Of course, you can choose formats. The options also include checking for defects, blockiness and blurriness, and in the last two cases you can set a threshold. It is possible to search in hidden and system directories.

  • AntiDupl program. ;
  • Russian language;
  • Distribution: free.

When searching for duplicates, some users are interested in 100% matching in order to get rid of duplicates in their collection. However, the task often arises of finding simply similar pictures.

And here there is a huge space for possible differences. This can be different formats, resolutions, cropped versions of the same image, adding frames and watermarks, changed colors and captions on the pictures.

We tried to take into account most of these factors and, after all the testing, we ended up creating a small set with more than six dozen pictures. In them we created nine groups of duplicates. Let’s be honest, our experience certainly doesn’t claim to be the ultimate truth, but it was interesting to try. The results are as follows:

  • Duplicate Remover Free: found only 3 groups of duplicates;
  • Similar Images Finder: found 4 groups, but the inconvenient interface, many false results, and the paid nature of the application greatly spoiled the overall impression;
  • AntiDupl found 3 types of duplicates by default, installing the SSIM algorithm increased the search result to 5 groups;
  • VisiPics found only 2 groups of duplicates at the basic search level, but setting the slider to the Loose level allowed it to find 7 groups;
  • Awesome Duplicate Photo Finder found 7 groups of duplicates;
  • Image Comparer was also able to detect 7 groups.

At the same time, Image Comparer was able to find images that Awesome Duplicate Photo Finder and VisiPics missed, and they, in turn, filled in the gaps of Image Comparer.

The fastest programs for finding duplicate photos

At the same time, the quality of the program also depends on its speed. 60+ pictures is, of course, not something that users can work with. So we did another test. This time for speed. To do this, we took a selection of 4450 of the most different images, the total weight of which exceeded 2.1 GB.

Unfortunately, two programs from this review did not take any place in the test. As it turns out, Similar Images Finder, which costs $34, free version ready to process no more than 200 images at a time.

In turn, the universal duplicate search engine Duplicate Remover Free, faced with a catalog of serious size, worked intensively for more than five minutes, and then completely froze. The remaining programs showed the following times:

  • AntiDupl: 0:39;
  • Image Comparer: 1:02 (35 seconds to create gallery and 27 to search);
  • VisiPics: 2:37;
  • Awesome Duplicate Photo Finder: 3:17.

As a result, Image Comparer and AntiDupl clearly took the lead in the speed test. It took them about or, in the case of AntiDupl, less than a minute to process our archive.

Conclusion

Let's summarize. If you need to find not identical, but rather similar photographs that differ, for example, in a signature or watermark, then Image Comparer, Awesome Duplicate Photo Finder and VisiPics in Loose operating mode will cope with this task better than others.

In terms of processing speed for a large collection of images, the undisputed leaders are AntiDupl and Image Comparer.

Finally, in terms of interface convenience, we liked Image Comparer and VisiPics, which immediately allow you to visually evaluate all groups of duplicates. In turn, for the clarity of comparing the characteristics of individual duplicates, we will also note AntiDupl.

Everyone has a folder on their computer in which they store various photographs or images, and it often happens that duplicates of such files appear on the hard drive. The question immediately arises of how to quickly get rid of them. The article will list a number of programs that are able to perform such actions quickly and efficiently.

It is a simple and easy-to-use program that can search in several ways and create galleries from selected images. What sets it apart from other tools is the presence of an assistant window, which makes using Duplicate Photo Finder even easier. Among the disadvantages are paid distribution and the lack of Russian language.

Duplicate Photo Cleaner

Duplicate Photo Cleaner is also an easy-to-use program that can also read a large range of graphic object formats. It has several ways to search for duplicates, and the presence of a Russian-language interface makes it stand out from most of the solutions described here. At the same time, Duplicate Photo Cleaner is paid, and the trial version has very limited capabilities.

Duplicate File Remover

Another powerful tool for finding duplicate photos is Duplicate File Remover. In addition to searching for images, it is also able to scan your computer for other identical files. The capabilities of Duplicate File Remover are significantly expanded by the plugins that are installed with it, but they can only be activated after purchase license key. Another drawback is the lack of Russian language in the settings, but this does not prevent you from using Duplicate File Remover for its intended purpose, since all actions here are performed on an intuitive level.

Duplicate File Detector

This is a powerful multitasking program that is able to instantly find identical documents in a specified directory. Duplicate File Detector supports a large number of formats that will be checked during operation. This is the only tool among the ones we reviewed that provides the ability to hash any file, for which there is a built-in hash calculator. Thanks to the latter, you can get the result in 16 hash code options. Using Duplicate File Detector, you can rename a selected group of files according to one of the proposed templates. The program has been translated into Russian, but is paid.

ImageDupeless

ImageDupeless is a powerful tool for finding identical images on your computer. In its functionality, it is very similar to the previously described Duplicate Photo Finder. There is the same assistant, the same search capabilities for identical graphic files, and the function of creating a gallery from images. But ImageDupless has a Russian-language interface, which makes it stand out from the mentioned program. The main disadvantage can be considered paid distribution and the fact that many features are available only after purchase.

DupKiller

DupKiller is one of the best ways to search not only for duplicate images, but also for files in general. It provides the ability to search almost anywhere on the computer, has a very wide range of settings, and supports plug-ins. In addition, it is distributed completely free of charge and translated into Russian, which makes it possible to use it without any restrictions.

AllDup

AllDup is a small free program that is designed to search for identical (including graphic) objects on the hard drive. It supports a large list of formats, which guarantees a high-quality search for duplicates. AllDup will also be an excellent option for computers that are used by several people at the same time. What sets it apart from the rest is the ability to create multiple profiles with certain settings. This feature will greatly save users time that would otherwise be spent on reconfiguring the program. You can also add to the list of positive qualities of AllDup the presence of the Russian language and free distribution by the developer.

DupeGuru Picture Edition

Using DupeGuru Picture Edition, the user will receive a free, simple and uncomplicated search engine for duplicate photos on a computer with a Russian-language interface. Among additional features It is worth highlighting that here you can export the results to a browser or to CSV format, which is read by MS Excel.

Dup Detector

Dup Detector is probably the most simple utility in the list provided. It does not have the Russian language and any additional features other than creating galleries from images, but at the same time it provides a choice of several options for searching for duplicate photos. In addition, Oak Detector is distributed by the developer completely free of charge and supports a large list of graphic formats.

This article reviewed programs that can be used to quickly and effortlessly detect duplicate photos on your hard drive and delete them permanently. Let everyone decide for themselves which tool to use, but it’s worth knowing that any of them will 100% cope with the task.

An excellent free program for finding duplicate files (pictures, photos, music, etc.).

Let's imagine this situation... Six months ago you purchased a brand new terabyte hard drive. And so, when you try to download another movie from torrents, your PC tells you that this is how it is, but there is no more space on your hard drive :). Nightmare!!! Guard!!! How can this be, it was a whole terabyte:(((?!!

And the whole problem may lie in the fact that too many duplicate files or even entire folders have accumulated on the new hard drive.

If you start manually rummaging through your “treasures” downloaded from the Internet, you can spend more than one day finally finding two identical installers of the same program or several copies of the same song!

But you can do much wiser - instruct your PC to carry out “soul-searching” and, based on the results of this process, decide what needs to be thrown away and what to leave.

However, in the basic version Windows functions there is no provision for searching for copies of files, so we will have to use third-party software for this matter. One of the best free solutions to this type of problem is the program DupKiller.

It can do almost everything you need for a comfortable and quick search for duplicate files, so it can easily compete with paid applications eg Duplicate File Remover:

Comparison of the DupKiller program with its paid analogue Duplicate File Remover

The only major drawback of DupKiller is the lack of support for NTFS Hard Links. That is, the program cannot create links to the selected file for it to work with several separate applications (without harm to the latter) :(.

If you are not going to rummage through folders with setup files of various programs installed on your PC, then DupKiller is just the tool that will allow you to put things in order on your hard drive.

Installing DupKiller

To install the program, we need, as always, to open the downloaded archive and run the installation file. In the first window that appears, we will be asked to select the installation language (we choose, of course, “Russian”), and then it all comes down to simply accepting the license agreements and confirming all offers :). Once the installation is complete, we will see the DupKiller working window:

DupKiller Interface

The program interface is quite simple and convenient. At the top we see a standard menu bar, which we will hardly use, on the left is a section panel, and on the right is a direct workspace with the necessary buttons and options.

A rather big advantage of DupKiller is the step-by-step automatic switching of tabs on the left panel after you perform one action or another. Thus, something like step-by-step wizard working with the program, which is undoubtedly very convenient for a user who is not familiar with the new interface.

By default, after launching DupKiller, we are taken to the “Disks” tab. Here we can use checkboxes to indicate those sections that should be scanned for duplicates.

For the first time, I advise you to perform a full scan in order to find out the real picture of what is going on on your entire hard drive, so don’t linger on this tab and click the “Scan” button.

After the process is initialized scanning hard disk, we automatically go to the “Statistics” tab:

Here the entire process of scanning the hard drive is displayed in a visual form. In addition to the log file window in which DupKiller operation statistics are recorded, we can obtain some information from the status line at the very bottom of the program’s working window.

First of all, this is the number of files found. While in the statistics section, we can pause or completely cancel the scanning process, but in the latter case we will have to start new search from the very beginning.

The scanning will not take too long (it all depends on the size of your hard drive). For example, I had 80 Gigabytes scanned in a little less than three minutes :). At the end of the process of searching for duplicates, we will be immediately redirected to the last section “List”:

Removing duplicates and other unnecessary files

In fact, this is the most important window of the program, so let’s look at it in detail. The first thing I advise you to do is expand DupKiller either to the full screen, or stretch its window horizontally so that it is convenient to see the entire status line at the bottom.

On it we will see the number of duplicate files, their total size, and when selecting duplicates to be ruthlessly destroyed, also the total size that will be freed up after their removal.

The next step is to sort all the duplicates found by the amount of space they occupy on the hard drive. To do this, you just need to left-click on the “Size” inscription (fourth column of the list).

After this, all files will be sorted in ascending order of their “appetites” by hard space disk. That is, the “heaviest” files will be at the end of the table, and the smallest ones will be at the top (you can do the opposite by clicking on “Size” again and waiting for a new list to be compiled).

Now you can start selecting unnecessary files. In the main list they are divided into groups that display duplicates of the same file in different folders (with their indication, of course).

For some types of files (text and graphic, and when the plugin is activated, also audio) DupKiller has a preview function. That is, as soon as you select a specific file, a window immediately pops up in which you can see its contents without opening it.

For small files, using this function seems quite convenient, but large files take quite a long time to open, which greatly slows down both the operation of the program and the system in general.

Therefore, I advise you to deactivate this function, by clicking the “Disable Preview” button (you can re-enable it by clicking the “Preview” button on the toolbar above the file list).

When all the preparations are completed, all we have to do is tick the unnecessary duplicate files and click the “Delete selected files” button on the toolbar. That's it - we got rid of excess ballast on the hard drive and freed up much-needed space for re-cluttering :).

As you can see, everything turned out to be quite simple - you will do it right the first time without any additional installations were able to “conquer” an impressive amount of space on the hard drive.

However, DupKiller is not without fine adjustments, but on the contrary, it is simply replete with them. As you understand them, more and more new functions of the program will open up for you! Let's look at the most important of them.

Additional functions

So, DupKiller allows you to scan not only the entire hard drive at once, but also individual folders:

Files and folders

To configure the directories to be checked for duplicate files, you need to go to the “Files and Folders” tab. There are two sections here.

In the top (“Searched files”) you can specify which types of files need to be compared (all are activated by default). And in the lower one (“Searched folders”), switching to the “Only specified folders” mode, set a list of folders that should be checked for duplicates.

Folders can be added either using the “Add” button or by simply dragging and dropping, which can sometimes be an even more convenient option.

Exceptions

The next tab - “Exceptions” - allows us, on the contrary, to specify those file extensions and folders that should not be included in the scanning process:

Settings

Working with this tab is similar to the previous one, so we will not focus our attention on it, but move on to the next section - “Settings”:

This is where you can have fun! :) Here we can set the criteria by which files should be compared, the degree of similarity at which the files will be considered the same, the sizes of the processed files, as well as many other parameters.

If these settings are not enough for you, then DupKiller also has “Other settings” :)

If in the previous section there were parameters related directly to the process of scanning files and folders, then these settings relate more to the program interface.

Here you can set the priority of the search process, change some parameters for displaying the list of duplicate files, and also work on saving and restoring settings. Regarding the latter, there is a little secret ;).

DupKiller can be made to work in portable mode (from a flash drive or disk). To do this, you need to activate the “Save settings” item in the “File” menu and save the file with program parameters in the folder where DupKiller is installed (by default C:\Program Files\DupKiller). Now all that remains is to copy the above folder to removable media and everything is ready ;).

The last group of program settings concerns the “Delete” parameters of files:

Here all the settings are extremely clear, so we do not focus on them, but consider the global Advantages and Disadvantages of DupKiller.

Advantages and disadvantages of DupKiller

  • byte-by-byte file comparison;
  • file preview function;
  • flexible scanning settings;
  • auto file selection function;
  • ability to use as a portable application.
  • There is no way to create hard links to files.

conclusions

As you can see, DupKiller has virtually no disadvantages, so it can be recommended as ideal free program for the war against clones of files on your hard drive! Good luck to you and may the FORCE be with you!!! :)

One of the most quick ways Score HDD— storage of duplicate files. Surely many people do not even suspect their existence... they can have different origins: random copies, many identical downloads, and so on. One thing is for sure - they can indeed cause you some problems.

Many duplicates are created due to the need to keep the file “safe”... for example, before editing a document, I could make a copy just in case, and then forget... or I already have such a document, and I downloaded it again from the mail. Unfortunately, there can be a lot of such doubles and it turns out that you score free place useless information.

With these tools, you can identify and remove duplicate files in minutes and free up a lot of valuable hard drive space. I will only consider free utilities, so you have nothing to lose!

Find duplicate files. Review of the best tools

This utility is probably my favorite tool for finding and removing duplicates, because it has a lot of great features: It is cross-platform, completely free, and also has an advanced tagging and selection algorithm.

What are not obvious duplicates? Several identical files may have different names. For example, you may have two files on your computer: example-file.avi And example file(1).avi— the utility understands this perfectly and can also mark them as a duplicate.

By the way, the utility also has other editions: Music Edition and Picture Edition, optimized for searching for duplicates of graphic and audio files - even if they are recorded in different formats. This is very important, because it is audio and graphic files that most often become duplicates.

Duplicate Files Finder is an application that searches for duplicate files (which have the same content, but not necessarily the same name) and allows the user to delete unnecessary files.

Duplicate Files Finder can only find exact duplicates. The principle of its operation is to sort through all the files on the computer by size and compare them by content. On the one hand, this is logical, but it is completely sad for video and graphics. (after all, depending on the compression algorithm, they can have different sizes), but for everything else the program is just excellent.

Thanks to this comparison algorithm, Duplicate Files Finder is much faster than its competitors.

AllDup is powerful tools to find duplicates created by one person, Michael Thummerer. The utility has a number of settings for searching for duplicates from: file name, extension and data type, date of creation and modification, and many other parameters.

AllDup has a lot useful functions and greater flexibility in terms of searching for duplicates, but you have to pay for the functionality. The interface here is not at all friendly and this can drive an unsure user into a dead end. However, if you can figure out the program, then this application will be good tool to find duplicate files.

Duplicate Cleaner requires fine manual tuning before you can use the functionality of this program one hundred percent.

At manual setting you can choose in which folder you want to find duplicates, and not scan the entire computer as some other programs offer us. As a result, you can delete these duplicates, move them all to a separate folder, or instead create shortcuts to a single required file. Overall the impressions are positive - so I recommend it.

If you Windows user, and want to get rid of endless copies of images, then SimilarImages will come in handy more than ever. Images, in my opinion, are the most common source of duplicate content on a computer. For example, I know that I have a bunch of duplicate photos in different folders... and given the number of them, I have no desire to deal with them manually.

The program has flexible settings and can detect inaccurate duplicates - this is especially important due to the presence of artifacts that appear during the image compression process.

The great thing about SimilarImages is that it shows you two images when it finds duplicates, and you can decide whether to keep them or delete the duplicate.

Conclusion

Everything is as in real life Just as unnecessary junk creates a terrible mess in your home, duplicate files can accumulate on your hard drive. Such files are very difficult to delete because you forgot about it, and ordinary system cleaning programs will not find them - since they reside on the hard drive for completely legal reasons.

Use the programs I have listed for you to find duplicate files to free up space on your hard drive. If you know about other utilities, share with us in the comments.
