Duplicate files program. How to find identical files on your computer

Removing duplicate files sometimes it takes a lot of time and effort, since this requires going through a considerable number of individual files, folders, and sometimes even disks. But with the advent of Duplicate Cleaner Pro, this task has become much easier. The program will not only help you find duplicates with maximum speed and accuracy, but will also efficiently remove them without leaving a trace.

This way of cleaning your computer from duplicates and similar files helps it work faster and better, because the hard drives will not be occupied by unnecessary files. As a result, not only the performance of the system will improve, but also the quality of its work. Duplicate Cleaner Pro helps you not only find files on hard and floppy disk drives, but also track the path, size and date of creation of duplicates.

Download the program to find duplicate files

You can download the program for searching and removing duplicates from the link below, completely free via torrent. Duplicate Cleaner Pro is multilingual, and Russian is also available. It has many search settings, for example by title, by content or by tags in music tracks. After finding a duplicate, Duplicate Cleaner Pro will remove it to the trash or move it to a new location you define. There is also a preview feature for duplicate images.

1. Install the program, do not run it.
2. Copy and replace the contents of the Crack folder into the folder with the installed program.
3. Register the program with any serial number.

One of the fastest ways to fill up your hard drive is by storing 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 duplicates and it turns out that you are filling up free space with 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 be reviewing 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 a powerful duplicate finding tool created by one man, 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 many useful features and great flexibility in terms of finding duplicates, but you need 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, this application is a good tool for finding duplicate files.

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

When setting it up manually, 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 the only necessary file. Overall the impressions are positive - so I recommend it.

If you are a 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

Just like in real life, when unwanted 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.

File garbage accumulated during computer operation usually consists of more than just temporary or unnecessary files. A separate category are duplicate files, which are identical in content, but are stored in different folders or on different computer drives.

This could be, for example, documents that were saved repeatedly, duplicate or similar photographs, the same music compositions that you downloaded from the Internet and saved in different folders or under different names. It is important to understand that duplicates are essentially two versions of the same photo that have different resolutions. Or the same song by the same artist, but recorded at different concerts. Or two versions of the same musical composition, but recorded in different audio formats.

An example of duplicate files can also be two versions of a movie, saved with different quality or, again, in different video formats. Of course, it is quite difficult to manually detect such duplicates, so we will call on special programs that search for duplicate files to help. As you probably already understood from the previous paragraph, duplicates of each type of file (drawings, music, videos, documents) have their own characteristics.

Algorithms for searching for duplicates of all types of files differ significantly from each other, therefore, as a rule, different programs are engaged in searching for duplicates of files of different types. Let's look at some of them. In addition, it is important not only to detect duplicates, but also to select the latest version of the document or the highest quality video or audio file. We will look at each type of file separately, and also provide a list of popular programs for working with duplicates.

Search for duplicate images

The most striking example of duplicate pictures can be the same or very similar photographs. Many modern cameras allow you to shoot in burst mode, when pictures are taken at very short intervals - from a few fractions of a second to several seconds. However, the resulting images differ from each other very slightly. As practice shows, there is no real need to store similar photographs; it is enough to select one or two successful photographs from a series and delete the rest.

Another case when duplicate image files may appear is when creating backup copies of photos on your hard drive, or selecting images for a presentation, in which they are copied to another folder. In general, the user often creates copies of images himself and then forgets to delete them. However, the reasons for the appearance of duplicate images can be very different. Our task is to get rid of such duplicates and clear up space on your hard drive. Among the most common programs designed to search for duplicate images on a computer are the following.

SWMole Clone Remover. Website address: http://www.clone-remover.com/. The program is paid. It can search not only for duplicate images (including similar pictures, not just exact copies), but also for copies of music files. In the unregistered version, the user has the ability to delete no more than 20 files. Finds copies of images in pairs, even if there are more than two similar images on the disk. Has a Russian-language interface.
Image Comparer. Website: http://www.bolidesoft.com/rus/imagecomparer.html. The program is shareware and has a trial period of 30 days. A multilingual user interface is supported, including Russian. It is possible to search for duplicate pictures both within one folder and between several folders. The program interface is somewhat complicated for a novice user, but it is possible to use a step-by-step wizard mode that will help you find and remove duplicate image files.
Picasa. Official program page: https://picasa.google.com. The program itself includes many different tools for working with photographs. The program also has a function to search for duplicate images. To use this function, you need to select Tools>>Experimental functions>>Show duplicate files in the main menu of the program. Let us immediately pay attention to the fact that the program searches for duplicate image files, that is, absolutely identical pictures. But it finds them regardless of location and with virtually no user intervention. The program is absolutely free and has a Russian-language interface. In addition, using Picasa, you can process images, apply various filters to them, find people's faces, mark shooting locations, and perform many other useful actions.
Similar Images Finder. Program website: http://www.crown-s-soft.com/ru/sifinder.htm. The program is shareware. You can use it for 30 days without purchasing, but there is a limit on the number of duplicate files found. The program interface is in English. It is possible to adjust the depth of “similarity” of photos, as well as set preferences for found duplicates: for example, you can tell the program to automatically delete the older duplicate file, which has less color or smaller size. The program has a duplicate search wizard that allows you to specify criteria for comparing image files in a step-by-step mode.

Find duplicate music files

Just like images, music files can sometimes take up a lot of disk space, and in some cases it can be difficult to manually find the same or similar music tracks. Specialized applications that automate this process will come to the rescue. Let's talk about some of the most popular ones.

Audio comparer. You can download the program on the website: http://audiocomparer.com/rus/. The application is shareware. It can be used for 30 days without registration. The analysis of musical compositions is based on a comparison of the names of performers and song titles. This data is taken from the file name and internal service information, the so-called ID3 tags. It is possible to specify the threshold of similarity of names at which the compositions will be considered the same. The application allows you to compare files both within one directory on your computer disk and between several directories. The program interface is somewhat complicated for a novice user, but this is compensated by the presence of a step-by-step wizard that facilitates the process of finding duplicates.
Music Duplicate Remover. Internet site: http://www.maniactools.com/. The key difference between this application and its analogues is the ability to search for duplicates by sound. This function allows you to find duplicates even among files that are incorrectly named. The program is shareware and allows an unregistered user to work for 30 days. It has a simple user interface in Russian.
SWMole Clone Remover. As already mentioned, this application can search not only for duplicate images, but also for repeated musical compositions. Program website address: http://www.clone-remover.com/. The program interface is a bit complicated, but thanks to the Russian language support, it’s easy to figure it out on your own. The application can search for duplicate music files only by file name and ID3 tags, without taking into account the sound. By using one of the programs listed or all of them at once, you can free up a lot of useful space on your computer's disks.

Finding duplicate video files

Dealing with duplicate video files has its own characteristics compared to finding duplicate pictures or music. Due to the large size of video files, there are usually not as many of them on computer drives as music or images. In addition, the appearance of duplicate films or videos is not as common as the “cloning” of photographs or songs. But deleting even one clone of a video file will help free up a significant amount of disk space. In addition, the algorithm for comparing video streams is much more complex than drawings or even the sound of music. For this reason, there are not many programs designed to find duplicate video files. Let's look at some of them.

Duplicate Video Search. Web address: http://duplicatevideosearch.com/rus/. The program is shareware - with a trial period of 30 days. It has an English-language interface, which, however, is not overloaded with unnecessary elements, and therefore is quite understandable. The user must specify in which folders to search for video duplicates. The application can compare the contents of video files of ten different formats. It is possible to specify the comparison depth.
Teemoon Video Matching. Program home page: http://teemoon.name/videoid/Default.html. Unlike its “brothers”, this application is free. Working with the program involves two stages. The first is indexing, which is done on the Indexing tab. This process creates index files for each video file in the specified folder. The process is lengthy, but it only needs to be done once, then the existing index files will be used when comparing files. The second stage is comparison, which is carried out on the Matching tab. The disadvantages of the program include the lack of support for the Russian language and a non-obvious operating algorithm.
Video Comparer. Program website: http://www.video-comparer.com/. The application has paid and free versions. The free one is quite suitable for home use. The program interface is quite simple. The user only needs to specify the folders in which to search for duplicate files and click the button to start the comparison process. The user interface is in English.

If you are a film fan and store a large collection of different films on your computer, or are engaged in video editing and have many video clips on your hard drive, then you should take an “inventory” of the video archive. Perhaps you will find hidden reserves of your computer.

Finding other duplicates

As you probably already understood, there is no universal program that allows you to get rid of all duplicate files in one fell swoop - each type of data requires its own tool. However, if you leave aside the complex algorithms for comparing images and sounds, and limit yourself to simply comparing the name, size and date of the file, you can find many duplicates among those file types that we have not yet mentioned here. These can be documents, files of other formats that waste disk space. To find such duplicates, you can often do without specialized programs. For example, if you use a popular file manager, you can use its tools to find and delete duplicate files. Among the file managers that have the function of searching for duplicate files are:

FAR Manager;
FreeCommander;
Total Commander.

If you are not used to using file managers, then you should not install them on your computer just to find duplicates. There are specialized applications for this task:

CloneSpy - http://www.clonespy.com/;
DupKiller - http://dupkiller.com/index_ru.html;
Duplicate Cleaner - http://www.digitalvolcano.co.uk/duplicatecleaner. html;
Free Duplicate File Finder - http://www.ashisoft.com/;
NoClone 2014 Desktop - http://noclone.net/

These and many other paid and free applications for every taste will help you get rid of duplicate files on your hard drives.

Deleting identical files (copies of the same file) or folders can free up free disk space and reduce unnecessary junk in the system, which is beneficial for speed systems. Sometimes duplicates are created by the user himself (for example, the same photos are copied to different folders located inside the same physical disk), in some cases they remain after using different software. The function of searching for unnecessary copies is performed by many applications, most of which are distributed as free ( for free). Let us describe the operation of several such applications.

Removing duplicates using Total Commander

We use Dupeguru

This software is designed solely to scan the system for copies and does not perform other functions.

AllDup to detect duplicates

The design of the program is made in a beautiful and easy-to-use style. Immediately after launch, a window appears with a brief management for finding duplicates. You can search the entire physical disk by checking the desired local disks.

Or add individual folders by clicking on the arrow next to the " Source folders" and selecting " Add folders».

Let's try to find duplicates in the Games folder in the local drive "C:\"

Activate the tab " Search method", set up the criteria. By default, the option to search for duplicates only by similar names, if necessary, tick the required settings. It is advisable to enable search by extensions, otherwise the software may show files with similar names even if they are not copies of each other.

Afterwards, press the button start search.

Once completed, a new window will open with results, in which we tick unnecessary files, right-click on file, which is supposed to be cleared of duplicates (open the context menu) and select “ Delete all other files from this group permanently" to delete copies. In this case, the original itself will remain untouched, only duplicates will be deleted.

How to use DuplicateCleaner Free

A very thoughtful application for finding and removing duplicates on your computer. In this case, you can perform search all files in normal mode, search for copies of images or music, or identical folders.

Launch the application. First of all, we set up the search criteria, for this in the section “ Additional options"check the setting" With the same name" and go to the tab " Scan path»

Select a folder, press the button additions selected folder into included paths and click the button " Scan».

We wait for the end of the scan, which will display statistics detected duplicates in a separate window. We close the window.

In the " Duplicate Files» the list is displayed identical files, mark unnecessary ones and press the menu “ View", select the item " Deleting files»

In the window that opens, click “ Delete file(s)" In this case, it is advisable to include deletion in Cart so that you can restore the necessary files.

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 find 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.

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 about deletion.
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, besides 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 far from 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.
