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 hidden directories. You can search for such duplicates using universal software or software designed for specific type 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 matching the number of bytes is different photos practically equal to zero, identical values are considered a sign of a duplicate.
Sometimes the algorithm involves checking names - also important parameter for searching, especially since the same data in most cases also coincides in 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. For example, none of these utilities will consider the same photo saved at different resolutions to be a duplicate.
1. DupKiller
The application, which allows you to search for files with almost any extension, can be downloaded for free on the official website of its manufacturer.
Among the differences of the program are the interface in Russian, fast operation and a large number of settings.
With DupKiller, you can compare files by size, date, and content (the latter feature is only supported for certain types).

2. Duplicate Finder
The Duplicate Finder application allows you not only to search for duplicate files with different extensions, but also to sort them.
For the convenience of users, the utility settings allow you to search by size, checksums, and name.
In addition, it can be used to delete empty folders and “zero” files. And among the shortcomings we can only mention the lack of support for the Russian language.

3. Glary Utilities
The program is not one utility, but several at once - for fixing the registry, for cleaning up the disk, and even for managing security.
One of the applications in the set allows you to search for duplicate files. Among the advantages of the utility is the Russian interface.
The disadvantages include a certain slowdown of the computer when using the application.

4. CCleaner
The main task CCleaner is a multifunctional program that cleans the computer’s hard drive (as well as tablets and smartphones, since the application also has versions for Android). 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).

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 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. TO additional benefits The application includes a Russian-language menu and 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 Linux and MacOS appear regularly).
However, even the relatively outdated utility for Windows 7 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
The utility for detecting copies of any file Duplicate Cleaner Free is different 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 from English. 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 music accumulated on a 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
Among the advantages of the Audio Comparer utility are a very simple menu and a quick search for copies of music. So, among several thousand audio files, she finds copies and duplicates (of course, if available) in just 1–2 hours.
In this case, neither the size of the track nor its bitrate matters for detection (bit rate, that is, sound quality, changing which leads to a different amount of data for the same duration of the melody).

10. DupeGuru Music Edition
The application is one of additional versions free utility DupeGuru. Its operating speed is lower than that of the universal version, but the probability of detecting a duplicate audio file is several times higher.
The operating principles and interface almost completely repeat the basic program, and one of the main advantages is that Music Edition considers music with the best bitrate to be “originals”. This means that deleting duplicates will not lead to the loss of higher quality audio files.

Finding copies of photos and other images
Just as often, the user may need to remove duplicate images. Especially if your hard drive contains several collections of personal photographs, 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 the HDD (SDD, flash drive or other drive).
11. DupeGuru Picture Edition
The application for finding identical pictures is another version of the DupeGuru utility, which can also be (and even desirable) 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– from .jpg to .png.

Finding copies of movies and videos
In addition to music and images, another type of data for which duplicates are searched separately are video files. After all, if you have 1–2 or even 4 terabytes of space on your hard drive, even movies can be “lost” on it.
Or home videos distributed across different directories. You can save space by deleting copies of videos using specialized utilities, the number of which is much smaller compared to applications for searching other files.

Conclusions
The advantages of programs for searching for copies of files are serious enough for at least one of them to be installed on every computer.
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.
Surely you have a large database of photographs. Has it ever happened that you are looking through photographs from this database and you get the feeling that some photos are repeated? Manually search for duplicate photos- long, painful and stupid. I agree with those who say that this is simply a useless exercise, because photographs do not take up so much space on your hard drive, but having well organized catalog of photos I still want to. Yes, and this article would not exist if there were no software method find duplicate pictures, so it won’t be difficult for you to do this!
To find duplicate photos, you can use the program AntiDupl.NET. The program is absolutely free, supports the main graphic formats: JPEG, GIF, TIFF, BMP, PNG, EMF, WMF, EXIF and ICON, and has a Russian interface. And in fact, it perfectly performs its main function, searching for duplicates.
From words to deeds. By downloading from the link above, latest version programs AntiDupl.NET, you will receive a self-extracting archive on your computer. By double-clicking on it, you will see the following window, where we will be asked to select a location to unpack the files. Unpack directly to your desktop.
As a result, a folder with a program ready for use will appear in the location you specified. Without thinking for a long time, we launch it. Initially, everything we have there is on English. To see your native Russian language, do the following: Click View - Language - Russian.
In Options, you can add a checkbox: Search for rotated and mirrored duplicates - since often some identical photographs turn out to be simply upside down.
Next, select the folder in which the photos are located and in which there are supposedly duplicates. To do this: Click on the folder icon - the Paths window appears - click add directory - select the desired folder - click Ok. If you need to search not in one, but in several folders, we perform this operation again.
To start the search, click on the green play icon.
As a result, the program will display a list of duplicate pictures. Next, you can either delete both or one of the duplicates.
If you set the options to Consider image size and Consider image type, then the program will find duplicates of only one size and only in one extension, respectively. I would not recommend checking these boxes, since you often come across the same pictures, only of different sizes.
"Finding duplicates in large collections of photographs"
Image Dupeless 1.6.3 (Russian) is designed to search for similar images (duplicates) in large collections. Graphic files in JPEG, GIF, BMP, PCX, PNG, TIFF, PGM, WMF, EMF, EPS, PSD, ICO formats are supported.

- ability to save duplicate search results;
- the ability to quickly update the gallery, bringing it into line with the files on disk without re-reading (for example, after moving the gallery to a new location);
- ability to specify a user-defined list of dissimilar images (for example, when you do not want to remove some very similar pairs and do not want them to appear in the list of found duplicates after each new comparison);
- the ability to automatically, according to user-specified conditions, mark “bad” duplicates for further removal;
- visual and convenient presentation of duplicate search results;
- the ability to vary the performance/convenience ratio by changing parameters;
- ability to work with image descriptions from the "descript.ion" file;

If analogues with zero size are found, they do not need to be deleted. This may be data that was created in another OS (for example, Linux).
Finding identical photos on your computer using Total Commander
Activate product. After launch, a window will open notifying you about the software status. Click on the button indicated in the window to activate another window. At the top of the menu, click “Commands”, look for “File Search” (combination Alt + F7). Next, you should select a location to scan (local drive by default). Total Commander will help you scan directories separately or the entire disk at once. Then go to the “Advanced” section and configure the necessary settings. At the bottom of the window, check the “Search for duplicates” checkbox, set the scanning settings and click “Start search” (Enter button). Once the procedure is completed, the results will be shown below.
This program created specifically to detect identical photographs and other copies on the computer. She “can’t do anything” anymore. The algorithm of actions is simple:
- open DupGuru;
- At the bottom there will be a button for adding directories to the list;
- tap on it, in the window that appears, select the desired directory, where the same objects are present, add;
- Click “Scan” and wait for the process to complete.
The utility will show the found copies in a new window or open a notification about the absence of such copies. Everything that is found will be eliminated in the “Actions” menu, you can also rename something, move it, etc.
We use AllDup
Program decorated beautifully and comfortably. After launch, a window opens with a small guide on how to detect similar photos. You can search throughout the entire space, or you can mark only the places you need. It is possible to add individual folders; to do this, simply click the arrow next to the “Add folders” item.
For example, let’s take Games in the “C:\” drive:
- go to the search method section and configure the parameters;
- The indicator for finding duplicates by similar names is automatically active; you can mark the necessary settings. It is better to enable the search immediately by extensions; otherwise, the program can only find objects with similar names, even if they are not copies;
- tap on the start key;
- A new window with results will open, where you mark unnecessary files, right-click on the one for which you want to delete analogues;
- Click “Delete all other files from this group permanently.”
The original remains, and the rest is erased from the computer.
This is very thoughtful utility, which finds and deletes identical photos and other objects on the computer. At the same time, you can search for photos, audio, etc. in standard mode, and look for analogues of pictures or audio, etc. The program is easy to work with. Just activate the program, configure the search criteria like this:
Additional options/Same name/Scan path
Mark the folder, click the button to add the selected folder to the included paths and click the “Scan” button. Wait for the scan to complete, where the statistics of found duplicates are displayed in a separate window. Close the window. In the “Duplicate Files” section similar objects will be shown, select the unnecessary ones, click the “View” menu, select “Delete files”.
Using the above services, it is easy to search for identical photos on your computer. You can choose any one, they all easily cope with the task.
Programs for finding and deleting identical files were considered. The procedure is, of course, necessary, but what to do if you need to detect and erase identical or similar pictures or photographs from your computer? Of course, use a special program.
The utility is called Awesome Duplicate Photo Finder and you can download it from .
It is free, small in size and has a version that does not require installation. The only thing that spoils it is the lack of a Russian-language interface, but it is so intuitive that it’s quite easy to understand. Especially after reading this article.
So, the main program window looks like this:
The found images are shown on the left and right, and the percentage of similarity is shown in the middle between them.
Below the images, their properties are displayed, such as extension, resolution and size (you can focus on them when searching).
By clicking on the picture you can open it in .

Move Files to Recycle Bin- delete file to trash
Delete Files without Confirmation- delete without warning
Search Only 100% Indian Pictures- search only for 100% matching images
Automatically Check for Updates- automatically check for program updates
Set it as you prefer, click OK and read on.
Let's look at this menu
it is needed to add folders for scanning and searching.
In order, the assignment of the buttons from left to right: Add, Delete, Move Up, Move Down, Clear.
Button Start Search- start searching.
Check mark on Scan Subdirectories- search by subfolders (which are inside).
After the search is completed, if there are results, the program window will look like this:
I deliberately covered up the paths, but the essence did not change.
The bottom part shows the path of the original image (Original Image), a similar image (Dublicate Image) and the percentage of similarity (Similarity).
There is nothing more to explain here, except that switching between found duplicates is carried out in the lower list.
This is how you can quite easily find not only identical pictures and images, but also photos on your computer.
