A program to detect identical files on a computer. Duplicate Remover Free - program for removing duplicate files

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

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 universal software or one designed for a specific type of data.

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 Windows operating system - from XP to 10.

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

Another useful application 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.

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 you need to clean your computer not only from 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 duration of the scan rarely exceeds a couple of hours.

9.Audio Comparer

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

The advantages of the Image Comparer application, in addition to its simple interface, include the presence of a step-by-step wizard that allows you to learn how to quickly and efficiently search for images.

This feature distinguishes the utility from most others, to work with which you will have to read help files that are not always correctly translated (and sometimes even provided only in English).

In fact, the application is another version of Audio Comparer, and is also distributed under a “shareware” license - that is, the user will have to pay for certain functions.

Rice. 13. The Image Comparer app is a good way to find duplicate pictures.

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 purchasing a 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 find not only duplicate images, but 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 specific 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 the additional features, it is worth highlighting that here you can export the results obtained to a browser or to a CSV format that is read by .

Dup Detector

Dup Detector is probably the simplest utility on 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.

Hello, dear ones. Remember, in my green website-building childhood (a whole year ago) I already recommended and described to you program for searching and deleting identical photos? So, it was an excellent program, but it was paid (although the solution to this problem can be found quite easily on the Internet). And here I also described the program in order to find and delete duplicate files . Damn, it's paid too! 😯

Today I will correct myself - I will describe to you a free and fast program for searching and deleting various copies of files on your computer, of which you have a lot. They sit quietly in the corners and giggle at you, increasing the size of the disk, slowing down the system (after all, scanning files is vital for its normal operation and is practically constant), simply littering the computer with unnecessary load, making it more difficult defragmentation process…

Duplicate files needs to be deleted and we will do this now. Naturally, I will describe everything step by step and in pictures, with all the nuances. And of course, I will give you two versions of the program - the regular one from the official website and the portable one.

Auslogics Duplicate File Finder is a free program for finding and removing duplicate files

Don’t even doubt it – there are duplicate files on your favorite computer. The nature of their appearance has not yet been studied by scientists. Over time, they grow like mushrooms, appearing out of nowhere... Of course, this is a joke - we create duplicates ourselves, without even noticing it. Let's get rid of them already. To begin with, of course you need to download the program.

As promised, here are two versions for you - everyone has the right to choose the one they need, but I highly recommend choosing the portable one. The fact is that in the standard version they will install (or try to) an additional toolbar in all browsers - do you need it? For example, no matter how hard I tried, I still caught him and barely got rid of him. (How? And like this.)

Download Auslogics Duplicate File Finder: 7 MB

Download Auslogics Duplicate File Finder Portable: 6 MB

Here's how I installed the regular version of the program...

Installing Auslogics Duplicate File Finder

Yes, the installation takes place in English, but remember that you and I are not afraid of difficulties and will overcome everything...

And here is the price of free - be sure to uncheck the boxes and who knows, maybe you will be lucky and the toolbar will not be installed.

Create an icon on your desktop?

Click “Finish” and the program for searching and removing duplicate files will start. Then everything is very easy and simple. As you can see, the program is entirely in Russian.

We select the disk on which we will search for duplicate files or even a separate folder...

We choose what exactly we will search for, or rather what types of files will be searched from...

If you are not very versed in the system, I do not recommend choosing the first, top item. The fact is that the system itself uses many identical files and places them where it is more convenient and faster for it to get to them - such duplicate files are not only not recommended to be deleted, but categorically bad!!!

To be on the safe side, create a restore point...

Here are my duplicate files. That's not all - I already found and deleted more than 300 MB during my first acquaintance with the program (I didn't just take screenshots).

Now we need to clarify for the program how to remove duplicates...

Hello Friends! In this article we will figure out how to implement find duplicate files on our computers. I admit, I don’t have such a problem. Usually, my computer has three partitions. The first system partition is from 50 to 100 GB, the second is for documents from 100 to 200 GB, and the third partition is for everything else. I have one folder for photos, one for music, and so on. Everything is transparent. The parents' computer is another matter. The hard drive is divided into three parts there. On the 3rd section there are two or three folders with photos + in each folder there are a bunch of subfolders. A photo folder was also subsequently formed on drive D. It’s hard to go through everything manually, and here programs for finding duplicate files will help us.

I don’t want to install a separate program for some function since there are many functions (for example, defragmentation or the same search for the same files). Accordingly, many programs will have to be installed on the computer. My position is as follows. The less you install, the more reliable and stable your computer works.

There are solutions. Find a program that is practically necessary for computer maintenance (that is, it will most likely be installed) and that would be able to search for duplicate files. It didn't take long to search. This is the already familiar and proven CCleaner from Piriform. Starting from version 4, CCleaner added this function and below we will see how it works.

Download the program from the official website

We install.

When you launch it for the first time, the window below will appear. If you select Yes, then when cleaning the computer by default, authorization on the above mail services may not be lost. Click Yes

Go to the Service tab on the left

Click on the Search Files button

To search for identical files, all you have to do is specify the necessary settings

There are not many settings and they are divided into three groups:

• Coincidence
• Pass
• Where to look and places to exclude

Let's look at each group in more detail.

Coincidence

You can search for duplicate files by Name, Size, and Modified Date. You can also combine these criteria by checking more than one box. When organizing photos on my parents' computer, the first thing I do is search for a match by Name. Most likely there will be a bunch of files saved in different places. Then, it will be interesting to search for a match by Size. Since the photo can be renamed, but the size should not change.

How to effectively use the search for duplicates with the Changed checkbox enabled has not yet occurred to me. If you have options, please write in the comments. Perhaps if you took and added something to the photo without changing the name. But, in this case, with great probability, the size will change.

Pass

Which files should be skipped when searching for duplicates. The following options are possible here:

• Bytes with size 0
• Read-only files
• Size less than x MB
• System files
• Hidden files

Where to look and places to exclude

Here, using the Add button on the Inclusions tab, you specify where to look for duplicate files. On the Exceptions tab, add places on your hard drive, flash drive, or external hard drive where you do not want to search.

In principle, everything is simple. To reset the settings, press the corresponding button.

When the filter is configured, click Find.

Sorting duplicate file search results

The result is an easy-to-view table with search results. Moreover, the table is formed immediately when any duplicate is detected.

Suspected duplicates are separated among themselves. The only thing I would like to see in this table is sorting by clicking on a column.

When you right-click on a file, a context menu appears that allows you to conveniently sort the search results. This is especially true if there are a lot of results.

The Exclude item allows you to remove all files from the folder you select. For example C:\Program Files. The Limit item will leave only files from the folder you select in the search results. The Select duplicates option allows you to select all files located in the folder you select. The remaining points seem to be clear.

The Open Folder option is very useful. Using it, you can quickly go in and see where the file is located and whether there are any identical files there that were not included in the results table or were eliminated by sorting.

All that remains is to figure out which of the files should be left and the rest deleted using the button at the bottom right.

Conclusion

This is how I’m going to look for duplicate files on my and other computers using good old CCleaner. For my purposes, the program's functionality is sufficient. If you need more, then DupKiller is worth a look. This is a free program, you can read about it and download it from the official website http://dupkiller.com/index_en.html. DupKiller has much broader capabilities to customize the search. It also includes viewing graphic files and listening to audio. An interesting feature is the ability to specify not an exact match of files, but up to a certain level (percentage).

Thanks for sharing the article on social media. All the best to you!

What a pity that hard drives are not rubber! I wanted to download a couple of movies for the weekend and install a new game on my PC, but it’s a shame - I’m almost out of free space. And you can’t free it, because only the important and necessary are stored on the disk.

Keep your nose up! You can increase the amount of free space by 5-50% without the risk of losing valuable information. How? By deleting identical copies of documents, photographs, audio recordings, videos and other goodness, of which several hundred accumulate over a year of computer operation. So, how to find and remove duplicate files in Windows

Unfortunately, the disk cleaning tool built into the system is not “trained” to search for identical copies of data, and we will have to turn our attention to third-party applications. Today's review includes 5 free utilities that do this job quickly, clearly and cleanly.

Auslogics Duplicate File Finder

Just the fact that it declares a certain level of quality and claims to be trusted by users. The program supports all editions of Windows, is regularly updated, has a Russian language and is very easy to learn. To search for duplicates, it uses a special intelligent algorithm - it compares not only names, but also the internal contents of files, which guarantees highly accurate results.

Auslogics Duplicate File Finder Features and Capabilities

• Setting up a filter by object type: all or only images, audio, video, archives and applications.
• Excludes files smaller and larger than a specified size from the search.
• Excluding names, file creation/modification dates, and “hidden” attributes from the search criteria.
• Finding duplicates with specific names or a given fragment in a name.
• 3 ways to delete duplicates: to the trash, permanently and by saving to the archive.
• Recovering data from an archive.
• Preview objects before deleting.
• Support for custom exclusion lists from scanning files and folders.
• Restore the system to a restore point from the program interface.

Using Auslogics Duplicate File Finder is easy and convenient. In addition, you don’t have to worry that the program will destroy any data without your knowledge and the possibility of recovery (unless you yourself have chosen the option to delete bypassing the trash can). The impression is spoiled only by the “unobtrusive” offer to install other products of the developer, which sometimes appears at startup.

CloneSpy

The utility is designed to search for duplicate files not only on the hard drive, but also on portable drives. It is a little more difficult to use than Auslogics Duplicate File Finder, but it is more functional and can work without installation on a computer - when running the installer, the user can choose its standard or portable version.

CloneSpy Features and Capabilities

• Supports any file types.
• Search for duplicates by identical content or the same name in combination with other criteria - extension, name, size.
• Finding objects of zero length.
• Many options for operations with copies of files: manual or automatic deletion (you can select in advance which object to delete - new or old), placing in a specific folder, creating a list of duplicates without deleting, etc.
• Any operations with found duplicates (including deferred ones) using batch command files.
• Replacing deleted copies with shortcuts or hard links.
• Calculation of checksums to be able to check objects for identity.
• Support for custom search filters.

CloneSpy functions quickly and smoothly, supports all versions of Windows, regularly receives updates, but does not have a Russian language, which makes it somewhat difficult to master. In addition, some users are put off by the Windows 98-style interface.

Soft4Boost Dup File Finder

The developers of the utility took care not only of functionality, but also of the beauty of their product: 11 stylish design options (skins) are at your service. In addition, the application is translated into 9 languages, including Russian, and has intuitive controls.

Soft4Boost Dup File Finder gets down to business right away - when you first launch it, a wizard window opens in the background of the main window, which will guide you step by step through all the setup steps. You won't be able to get confused and make mistakes.

Functions and features of Soft4Boost Dup File Finder

• Finding copies of objects by content.
• Select a search category: among all files or only images, audio, video, archives or applications.
• Option to ignore object names.
• Scan local and network folders, as well as removable media (you can select several).
• 2 ways to delete: to the trash and permanently.

Unlike many “free” applications that try to recoup their free nature by installing garbage or intrusively displaying advertising, Soft4Boost Dup File Finder only modestly offers to buy products from the same developer in bulk for 1,399 rubles. If you don't need them, just don't click on the banner.

Like the rest of the programs in today's review, Soft4Boost Dup File Finder supports all versions of Windows and is updated regularly.

AllDup

The utility is not as intuitive as the previous one, but it is rich in functions. Without the Russian language, not everyone would be able to master all the features in 5 minutes. Although there is nothing complicated in this program. When you first start it, a small prompt opens along with the main window - the “Quick Start” window with three buttons: “Select source folder”, “Select search method” and “Start search”. Pressing these buttons in turn opens areas where you need to select or configure something.

Users who speak English can learn AllDup using the built-in help, which opens in the right place by clicking on the question icons.

AllDup functions and capabilities

• A large list of search criteria: name, extension, size, content, creation and modification dates, file attributes, hard links, similar images. Search by a combination of several criteria.
• Scanning the contents of archives (finding individual duplicates in archives).
• Customizable way to compare object names: by complete match, by the initial characters in the name, by a specified number of matching characters, etc.
• Finding files with similar names.
• Comparison of file contents.
• Flexible search options with the ability to select additional actions before and after it.
• Maintaining a scan log.
• Flexibly customizable filter for ignoring objects.
• Creating a hard link or shortcut to the saved file in place of the deleted duplicate.
• No restrictions on the number of directories scanned.
• Scanning removable media.
• Preview of found files with display of various parameters - in case of difficulty when making a decision to delete.
• Compiling convenient lists of search results. Export lists to txt or csv format.
• Saving the scan result. Allows you to close the program without waiting for the scan to complete. And after restarting, start not from the beginning, but from the moment you stopped.
• Create and save multiple settings profiles.

AllDup differs from many competitors in its high scanning speed and complete detection of duplicate objects. By the way, thanks to the search for similar files function, the program can be used to find any data on the hard drive without the purpose of deleting it.

Another nice feature of the AllDup utility is the complete absence of advertising. Instead, on the top panel there is a button “Support the author” with any acceptable amount, if you want it yourself.

DiskBoss

It cannot be completely classified as a program for removing duplicate files. This is just one of the functions, in addition to which the utility can do a lot, very much. DiskBoss is a disk space optimizer and advanced file manager. It is designed to analyze the use of drives and manage all the objects that are located on them.

DiskBoss Features and Capabilities

• Disk space exploration with a pie chart showing how much space each object takes up.
• Classification, sorting and grouping of files and folders according to multiple criteria, including user rules.
• Finding and cleaning duplicates on workstations and servers running Windows. Flexible search criteria.
• Several options for dealing with found duplicates - deleting, archiving, moving to another location, etc.
• Replacing deleted duplicates with links.
• Saving scan reports and cleaning disks from duplicate data in html, excel, pdf, txt, csv and xml formats.
• Displaying duplicate search results on pie charts.
• Creation and execution of automatic disk cleaning scripts.
• Improved disk data search system.
• Synchronizes data in specified directories.
• Delete groups of files based on specified criteria.
• Monitoring changes in the disk file system in real time.
• Integrity analysis and other operations with files.
• Much more.

DiskBoss is a good choice for those who need a complete picture of the contents and status of their disks, as well as the ability to manage all the data on them using manual and automatic methods. The application comes in a free version and several paid versions, with the first containing almost everything that is in the paid pro version, except for a few automation tools.

Perhaps the only drawback of DiskBoss is the lack of Russian language, but for the sake of such a wealth of functions you can put up with it. Otherwise, the utility is very good, and for some tasks it is irreplaceable.

Of course, this is not an exhaustive list of programs designed to delete identical copies of files. There are dozens of them, maybe hundreds. However, this modest set is enough to satisfy the needs of 90% of Windows users. I hope that some of them are useful to you too.
