The special program does not see duplicate files. Finding and deleting identical files

Not all duplicate files found in CCleaner can be deleted. Please remember this and use this tool wisely and with caution.

The program searches for duplicates using the following criteria: name, size, date and content. By default the name, size and date are marked. Find all identical files using these parameters on your computer.

A few seconds after pressing the " Find» the results will appear. Look at them carefully.

If you see duplicate library (.dll) files, the files in Program folder Files, files with extensions unknown to you, then do not touch them!

If you don’t know what these files are, why they are needed and where they came from, then it is better not to touch them (so as not to disrupt the functionality of the programs installed on the computer).

Look only for files that are familiar to you, those that got onto your computer thanks to your participation. For example, a film, photo, song, essay, etc. Do you see that you have the same abstract on your desktop, in “My Documents”, and in some other folder? This means you can delete all its copies except one (unless, of course, you deliberately created them as part of backup on different disks).

If the file whose duplicates you are going to delete is important, open the folder containing it and check manually whether these are actually 2 copies of the same file, and whether the program made a mistake (which is extremely rare, but in the case of important documents it is better to be safe). To open this folder, right-click on the desired found file and select “ Open folder».

Once you are sure that the copies can be deleted (or if you did not do this, but are just sure of it), check them and click the delete button.

You can do the same with your other found files. Favorite song copied 5 times and stored in different folders? Each copy weighs 10 megabytes, for a total of 50! Fuck them! Leave one in the folder with the rest of your music, and you can delete the rest, freeing up precious space for other files.

Remember one thing: Finding and removing duplicates in CCleaner is not complete automatic tool. The search takes place in automatic mode, and you make the decision to delete “manually”. Therefore, be careful in this matter.

What is not stored on the hard drive! Copies and copies of copies, created just in case, gradually disperse into different folders, and now we forget about their existence. If you decide to restore order and free up space by deleting unnecessary duplicate files, they will come to the rescue special utilities ForWindows(most of these programs are free).

DuplicateRemoverFree

The program has a fairly simple interface, but provides many opportunities. Duplicate Remover Free allows you to search for files with the same size and name, as well as duplicate images and duplicate documents. You can scan an entire disk partition for duplicates or exclude individual directories from the search (for example, directories with backup copies or system folders). Also search for identical sound files and video recordings can be made using file tags (which can be useful, for example, when updating your home music library).

DuplicateFileFinder

Program Duplicate File Finder from Auslogics has similar functionality. The utility can find duplicate files of all types. In addition, it can only search for copies of audio files, images or videos - thus, system files are guaranteed to remain safe.

AllDup

AllDup is another program that also cannot be ignored. This one is powerful free utility for Windows allows you to search for duplicate files based on several parameters: same name, same size, duplicate creation time, etc. U supposedly identical files the program checks checksums(you can select the calculation algorithm in the settings), so the probability of deletion different files one size zero. The utility can also search similar images V JPG formats, PNG, etc. This can be useful when deleting copies from a home photo archive (for example, duplicates of the same photograph - with and without a frame). AllDup is distributed both as a classic installer and as a portable version that does not require installation.

DupeGuru

This utility can be recommended to fans of cross-platform solutions. The program is released in the form of packages for Ubuntu and Mac OS X (there is an unofficial version for Windows 7, which is fully functional in later versions of the OS). Using it is quite simple: select the directory in which we are looking for copies of files and start scanning. After some time, the program will find duplicate files and you can delete them.

Windows"Disk Cleanup"

Don't forget about the standard Windows program, which will help free up some space. This utility does not search for duplicate files, but it can remove some outdated and unnecessary information from the system.

1. To launch it, press the Win+R key combination, write cleanmgr.exe in the input field and click on the OK button.

2. Select the disk that we want to clean.

3. Check the boxes next to the required items (you can almost always safely delete temporary files, sketches, and DirectX texture builder cache) and click OK.

4. After a few seconds (or a couple of minutes - depends on the performance of the computer and the number of files) unnecessary information will be deleted.

In modern Windows versions You can also use other built-in system tools. For example, you can launch PowerShell, go to the directory you need with the cd command and execute the following script:

ls *.* -recurse | get-filehash | group -property hash | where ( $_.count -gt 1 ) | % ( $_.group | select -skip 1 ) | ls

After some time, PowerShell will display a list of files of the same size. If you replace the last ls command with del, the files will be deleted immediately (but it is better to look through the list and delete everything unnecessary manually, so as not to accidentally destroy useful information).

However, I would like to remind you that it is extremely undesirable to manually delete duplicate files from the system directories of drive C (Program Files, Program Files (x86), Windows, etc.). The result of such “cleaning” of the disk may be inoperability operating system. The same applies to deleting files from the /etc, /bin, /usr directories on UNIX-like systems. Particular care should be taken when deleting files using administrator (or root) rights. And, of course, do not forget about backups - there is a small chance of accidental deletion necessary information always exists, so it's better to be safe.

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

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

Universal Applications

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

And, since the probability of matching the number of bytes is different photos practically equal to zero, same 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.

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).
