Many users are unaware of how many identical copies of files are stored on their hard drive. Meanwhile, they all take up space that could be used for something needed. If you're running out of space on your hard drive, searching for duplicate files on your computer is one of the best solutions to free up some space.
You may have copies of files in a variety of formats stored on your computer: images, music, videos, or any other format. Such files can be stored in different directories and on different disks (if you have several of them). In addition, they may also differ in size or even extension. Therefore, searching for them by hand is a difficult and time-consuming task.
The best solution for finding duplicate files on your computer is special software. Now there are many different programs that search for and remove duplicate files, and they are all divided into two types: universal and focused on a specific type of data (music, images and video). The first option will allow you to quickly and easily remove duplicates of any format, however, compared to the second, it is much less accurate. So choose which one is preferable for you, and let's look at the most popular programs together.
Universal programs for finding duplicate files on your computer
As mentioned earlier, universal programs are capable of searching for duplicates of any format, but are inferior in accuracy to more targeted versions. There are two main parameters by which such programs compare files with each other: size and checksum. Although this approach increases search speed, it allows you to find only completely identical files, and not all of them. If you are satisfied with this option, then let's look at the most popular programs among Internet users.
Without exaggeration, the DupKiller program can be called the most popular in our homeland. And it’s not surprising, because it has quite a lot of advantages and practically no disadvantages. The first thing that captivates us with this program is, of course, complete and high-quality Russification. The second is the speed of work, it is very high here, and this despite the fact that the accuracy of the search here is pleasantly surprising. In addition to size and content, DupKiller also compares files by their modification date. The developers have not forgotten that the program is universal, and therefore it compares almost all currently existing file formats. Add to this a convenient interface and extensive customization of functions and you will understand why this program is so loved.
You can download it for free on the official website.
The Duplicate Finder program is not much inferior to the previous version and even has several individual advantages. Thus, the program not only finds similar files, but also sorts them. In addition to finding and deleting duplicate files, it also deletes empty folders and “null” files. The search here is carried out by size, checksum and file name.
Despite all this, the program is still not as popular among Russian users as DupKiller, although the main reason for this is most likely the lack of a Russian version of the program.
Glary Utilities
The third most popular program for finding duplicates on a computer is Glary Utilities. The peculiarity of this program is that it performs a number of different functions to speed up the PC: from cleaning the registry to managing security, and deleting identical files is just one of its many functions. The program is completely translated into Russian and is freely available. Its only drawback is the serious load it places on the system, which is why the computer can seriously freeze while the program is running.
Programs for finding copies of audio files
Programs for finding copies of audio files will definitely be useful to music lovers who store large amounts of music on their PCs, and especially to those who like to download various collections of music, because such collections very often contain the same compositions. The statistics are that approximately every tenth audio recording from the seasonal selections of the best music is already on your PC. So consider this: if you have, for example, one hundred gigabytes of music on your PC, then at least ten of them are duplicates.
The situation is further complicated by the fact that such files may differ in both name and size. The only criterion by which such copies can be found is an audio track, which can be distinguished either by ear or using special programs. We will talk further about the best programs capable of finding duplicate audio files.
The best qualities of the Music Duplicate Remover program are its speed and search quality. The principle of its operation is that it listens to all audio recordings and remembers them, and then compares them with each other and looks for matches. Of course, such a procedure takes much more time than checking universal programs, and therefore the speed here is fast only when compared with similar programs. The average scan time is about two hours per hundred gigabytes of files (which, by the way, is about three songs per second).
The Audio Comparer program is quite similar to the previous version, both in terms of the search principle and in terms of effectiveness. She is not inferior to her either in speed or accuracy. It is worth mentioning separately that it has a kind of wizard that helps users understand the basic principles of the program when they are just starting to work with it.
Another program that deserves your attention is Dupe Guru Music Edition. Even the original version of Dupe Guru is quite competitive and boasts excellent speed and accuracy. But what is especially interesting is the small modification made by the developers in the Music Edition.
In the work of programs that search for duplicates, there is such a thing as “original file,” which means a file that will not be considered a copy and, after cleaning, will remain on your PC. Usually, the original is the file that was found before its copies; in rare cases it is given to the user to choose.
But Dupe Guru Music Edition, in addition to the usual comparison by sound, also makes a comparison by the quality of the audio file and, after completing the check, makes the original the file whose quality was higher than that of the others. That is, after deleting copies, you will only have the highest quality version of the composition on your PC.
Duplicate photo file search program
A large number of identical images in PC memory is also a very common problem among users. But at the same time, searching for identical pictures manually is almost the most difficult thing. In addition to the fact that the same images can be of different formats, resolutions or quality, they are usually not labeled, unlike the same video or audio files. Viewing and remembering all the pictures yourself, and then looking for copies in nameless lists is a thankless task, and therefore the help of a program that will search for duplicate files on the computer for you will be more useful than ever. Below are the best programs for finding duplicate photos on your computer.
Image Dupeless
The first program that will suit you for this purpose is Image Dupeless. This program will quickly find all similar images that are on your computer and offer you a detailed list of them with the ability to compare them with each other. The approximate time for checking this program is about half an hour per gigabyte of files (which in turn is about one thousand images of average quality).
The program is completely translated into Russian and is distributed free of charge on the Internet. At the same time, it is one of the easiest programs of this kind.
The Image Comparer application is shareware, which means you can download it without any investment, but you will have to pay extra to use certain functions. In terms of speed and size, the program is not inferior to Image Dupeless, but in addition it has several more advantages. Many users call the main advantage “a wizard for working with the program,” which helps you get comfortable “at first.”
However, what really looks interesting is the file verification procedure. The Image Comparer program will not only find copies of files, but will also set the percentage of their matches and even mark different places directly in the photo. This approach greatly simplifies checking for duplicates.
Based on all of the above, we can without a doubt call the Image Comparer program the easiest to use.
Once again the Dupe Guru program, but this time a slightly different version. Searching using Dupe Guru Picture Edition takes a little longer than using other applications, but the search quality is much higher. The program compares absolutely all images stored on your PC, regardless of their format, resolution or size.
Finding and removing duplicate video files on your computer
Here we come to the last type of duplicate files - video files. Of course, in order for identical films to appear on your computer, there must really be a lot of them, but in this case, even one copy will weigh up to several gigabytes, and therefore it is definitely worth checking. Several applications will help you with this.
Duplicate Video Search will allow you to find identical video files quickly and efficiently. It searches for copies based on video titles, sizes, and bitrates. In general, the program is nothing special, but it still has one interesting function in its arsenal.
We have already encountered the concept of “original file”, and now it’s time to remember it again. The fact is that the Duplicate Video Search program, just like Dupe Guru Music Edition, selects as the original file the one whose quality is the highest and it is the one that will remain on your computer after the search for duplicates is completed.
The main advantage of the Video Comparer program is its speed. The program uses a rather interesting algorithm, in which it compares not the entire video, but only its individual fragments, which saves verification time.
The program also has disadvantages, for example the lack of Russian localization. True, thanks to the simple and understandable interface, this does not greatly affect the work process, and you can use the application on an intuitive level.
What really hinders the growth of the application's popularity is the lack of a free version. What Video Comparer can offer you is a trial period of thirty days, and then you will have to pay 20 euros for further use of the program.
This concludes the article about finding duplicate files on your computer. As you can see, this procedure can hardly be called difficult, but it will allow you to free up quite a lot of space on your computer. Checking for duplicate files will never be superfluous, because, as mentioned earlier, many users do not even realize how many identical files they have before checking everything.
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!
Carrying out effective general cleaning of your computer's disk space, along with using automatic Windows cleaning programs, also requires manual work to remove unnecessary files and duplicate files. To track unnecessary files, special programs are designed - disk space analyzers; they help filter the contents of computer disks according to certain criteria (in particular, by weight) so that the user can decide whether to delete files or leave them. There is also special software to search for duplicate files - either in the form of separate programs or small utilities, or as part of comprehensive software for cleaning and optimizing Windows. Below we will look at five programs for finding duplicate files. The top five included completely free programs with support for the Russian language.
When searching for duplicate files on the system drive C, it is better to indicate not the entire partition, but only individual folders where user files are stored. Duplicates found in Windows working folders cannot be deleted. If you find some heavy folders or files with unfamiliar names on your C drive, it is recommended that you get help about them on the Internet.
1.AllDup
AllDup is equipped with many different options for fine-tuning the search for duplicate files. Customizable options include choosing a comparison method, search criteria, priority for checking duplicates, using exclusion filters, including the contents of archived files, etc. It is even possible to change design themes and individual interface settings. The program is good, however, with a somewhat ill-thought-out interface. On its toolbar, all tabs - be it basic operations or additional functions - are listed as equivalent. And to help the user who launched AllDup for the first time master the specifics of the program, its creators equipped the interface with a floating widget in the form of a short guide, which step should be taken. In the “Source Folders” tab, you specify the search area - disk partitions, connected devices, or individual user folders on the system drive C.
Next, in the “Search Method” tab, set the search criteria. Here you can specify the search for duplicates and add extension, size, content, etc. to the preset search criteria for file names.
Duplicate search results can be sorted by size, path, file modification date, etc. Detected files can be deleted, their location can be opened in Windows Explorer, and other actions provided by the program can be applied.
To return to analyzing AllDup's duplicate search results at a later time without waiting for the scan to complete, the current results can be saved to a program file format or exported to TXT and CSV files.
The AllDup program has a portable version that does not require installation on the system.
2. Duplicate Cleaner
Another functional program for a highly customizable search for duplicate files is Duplicate Cleaner. The Duplicate Cleaner program exists in two editions - paid Pro and free Free. Although the latter is limited by the unavailability of some functions, its capabilities will be sufficient to effectively search for duplicates. Duplicate Cleaner Free allows you to set search criteria by file name, content, size, and creation date. Additional search criteria are provided for audio file data, as well as filtering by content types and file extensions. All these points are configured in the first tab of the program “Search Criteria”.
In the second tab of the program – “Scan path” – the search area is selected.
In the search results window, duplicates can be sorted, deleted, their location can be opened in Explorer, and other program options can be applied to them.
Duplicate Cleaner search results can be exported to a CSV tabular data format file. Data export is carried out both for the entire list of duplicates, and for only files marked by the user. Duplicate Cleaner's advantages include a user-friendly interface and well-thought-out organization.
3. DupeGuru
DupeGuru is the simplest duplicate file search engine for those who do not have the time or desire to master all the intricacies of functional, highly specialized programs such as those discussed above. At the bottom of the small program window, a search area is selected and scanning starts.
Duplicate search results can be sorted by location path and file size. The context menu of DupeGuru search results contains only the operations necessary to work with found duplicates.
Search results are saved to a program file or exported to HTML.
DupeGuru is a cross-platform program, but only its older versions are adapted for Windows. The program installer for Windows 7 offered on the official website is also suitable for system versions 8.1 and 10.
4. CCleaner
At one of the stages of its improvement, the most popular cleaner for Windows, CCleaner, received a function to search for duplicate files. You can use this function in the “Service” section. To search for duplicates, search criteria are available by name, creation date, file contents, and file size.
Like the previous participant in the review, the CCleaner program in the duplicate search results environment is not particularly rich in functionality, but the basic operations are present. This, in particular, sorts search results and deletes files.
5. Glary Utilities 5
A comprehensive program for cleaning and optimizing Windows, Glary Utilities 5 includes a utility for finding duplicate files. The same utility, if desired, can be downloaded separately from the official website of the program if the full power of the software package is not required.
The duplicate finder included in Glary Utilities 5 is simple, but convenient and customizable. You can start scanning duplicates immediately by selecting only the search area - disk partitions, removable devices or individual folders. You can further refine your search by clicking the “Options” button.
The options configure the criteria for searching for duplicates - by name, by size, by time of file creation. In some cases of thorough cleaning of disk space, you can change the preset selection of searching only among common file types to scanning all types.
The search results provide only the necessary operations for working with duplicates, in particular, deleting and opening the placement path in Windows Explorer.
For the convenience of the user, Glary Utilities 5 catalogs found duplicates by content type - documents, pictures, videos, programs, etc. For each type, the total weight of found files is displayed.
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", setting 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.
