Deleting duplicate files on the computer. The best programs to find duplicate files on your computer. What files to delete

"a new one has come -" how to figure it all out? " hard drives have reached the point that a dozen DVD images can be accidentally lost on them, not to mention hundreds of photos. You may not notice unnecessary and repetitive files until the moment when the space suddenly runs out. But before buying a new one HDD, it makes sense to clean the old one for duplicates. Possibly after general cleaning there is a problem free space will no longer stand so sharply. Searching for duplicate files manually is time consuming and inconvenient. It's much easier to use one of the special utilities that do most of the work for you. If you are ready for revision hard disk all that remains is to find the right tool.

Interface: english Duplicate Finder can perform two main tasks: search for files by specified criteria and sort them. Search capabilities include byte comparison, checksum verification, and search for files with the same name and size zero. Additionally, you can install protection on system folders, exclude from search scope hidden folders and files, and enable Fuzzy Logic mode. In this mode, files with minor differences will be shown as identical. You can include several folders in the search area at once, and for each set its own exclusion parameters. So, within each folder, you can limit the search to files of a certain type, size; there is also a date limit. The types of allowed files do not have to be entered manually - there are many profiles for file types, for example, text, video, audio, etc. Each profile is easy to edit. Folders in which you should not search are specified separately. This feature is useful when the search area is not just individual folders, but the entire hard drive. In this case, it is convenient to specify the folders that you want to skip. The same goes for file types - you can specify which extension you want to skip.

Found duplicates are displayed not during scanning, but after the search is completed. While Duplicate Finder is running, you can see the progress of the job and how many files have been checked in the status bar. The search results will be presented as a list. You can distinguish which files are duplicates by color: every second pair of identical files will be highlighted in blue. To be honest, such a selection cannot be called very visual - it would be much more convenient if a different color were used, but we did not find the possibility to change it in the program.

The list of found files shows comprehensive information about each of them: path on disk, extension, size, date of last modification. Using the commands of the context menu or buttons on the toolbar, you can quickly move a file to another folder, delete it, or copy it. In addition, you can view the properties of the file, open the folder in which it is located in Explorer, or open the file itself. It should be noted that there are quite wide options for selecting files in the list. For example, there is a command to quickly select all found duplicates, to select all files that belong to the specified folders, as well as by size and creation date.

Some graphic files can be previewed directly in Duplicate Finder, however, the list of supported formats is not very large. For example, the .jpg and .bmp files opened in the built-in viewer without problems, but the .tiff files could not be viewed. For a commercial program designed to search for duplicates, the standard "trial version for 30 days" scheme is not suitable, since during this time it is quite possible to have time to search for unnecessary files at all hard drives, and the application will simply be unnecessary. Therefore, the developers of Duplicate Finder took a different approach: in the evaluation mode, using the program, you can move, copy or delete up to 50 files, the total size of which cannot exceed 2 MB. However, nothing prevents you from deleting duplicates found with Duplicate Finder from the file manager, but this is not very convenient. Although, if you choose this, in general, not a very honest way, then keep in mind that the Action menu has a convenient Copy File Path To Clipboard command, which is duplicated by the CTRL + W keyboard shortcut. When this command is executed, the path to the selected file is copied to the clipboard. It remains only to insert it into command line file manager, and you will quickly find yourself in the right folder.

Interface: Russian Free program DupKiller may well outperform many commercial counterparts. The utility has a rather convenient and, moreover, a Russian interface and boasts flexible settings for finding duplicates. In addition to the standard options for comparing files by name, size, creation date and type, here you can find an interesting feature of comparison by content. At the same time, the user can determine where to start comparing files - from the beginning or from the end, and also indicate at what percentage of "similarity" they can be considered the same. It is also worth paying attention to the ability to search for files with similar names. By choosing this function, you can determine how different the files should be in name, so that the program treats them as duplicates.

Exclusions are also flexibly configurable: you can specify the minimum and maximum size of files to search, specify valid attributes for files and folders, as well as file and folder extensions that should be excluded from the search. DupKiller can search for duplicates not only on hard drives, but also on virtual, RAM and CD / DVD disks. It is very convenient that for each medium its total size is displayed, as well as the amount of free space in gigabytes and percentages. After removing unnecessary files, you can compare the results and evaluate how useful the program was. With its help, you can also determine which files have already been copied to DVD, and therefore can be painlessly removed from the hard drive. During scanning, the program keeps a detailed log of operations and reports what action it performs in this moment... After the operation is completed, a window appears with a message about how much time was spent on the search, how many duplicate files were found, and how large they are on the hard disk.

The list of found duplicates is clear enough: files are divided into groups that are visually separated from each other. Clicking on the file opens a window preview... Viewing is available for many graphic files, as well as for all text files. And by connecting the plug-in, which is included in the DupKiller package, but is disabled by default, you can listen to audio files without leaving the program.

The possibilities of working with the list of duplicates are also great: there are buttons for quick removal selected and marked files, automatic selection of files based on a number of characteristics. Deletion options are configured separately - you can move files to the "Trash" or delete them permanently.

Interface: English NoClone is perhaps the most famous duplicate finder, and its popularity is understandable. Its not very pretty appearance more than compensated by a large number of functions. The program can perform a byte-by-byte comparison of files, find identical MP3 files by ID3 tags, and search mail for identical letters. With the help of NoClone, you can find not only duplicate files, but also make a selection according to a specific criterion, for example, display a list of all files larger than 500 MB, or all files that have changed within a specified period of time.

If you do regularly backup, and also perform data synchronization between two computers, you invariably accumulate a large number of versions of the same files. Thanks to its Similar Files search function, NoClone allows you to find and remove them. In the program settings, you can define by what percentage the files should be similar in order for NoClone to show them in the list of duplicates. The list with found duplicates is quite descriptive: you can see the name, size, location and date of the file in it. The function of previewing images is very well thought out - if in other programs the images are shown in a small pop-up window that appears when you select graphic file in the list, there is a special preview panel. It can display several files at the same time.

The Smart Marker tool will help you deal with the list of duplicates. With its help, you can select the found files according to criteria such as size, date, name, number of characters in the name, location. In addition, there are special checkboxes "leave at least one unselected file in the group" and "select files in each group". Another feature of NoClone shows up when it comes to deleting files. Besides standard ways deletions - placing duplicates in the trash and complete removal- the program has another interesting option: replacing the file with an NTFS link. In other words, the program leaves only one file on the hard disk, and instead of all copies it creates links that lead to it. This can be very useful when duplicates found with NoClone are used by other applications, for example, when it comes to a library of virtual disks in the Alcohol program. If you delete the file, you may receive error messages when launching such applications. If an NTFS link is created, the program will "see" the file at the old address, but in fact it will not be there. Developer: Marcus Kleinehagenbrock

Interface: English CloneSpy is a compact free utility for finding duplicate files with many interesting solutions, which the creators of many commercial programs may well look at. First, there is a very convenient window for adding folders to the search area. In most programs, to add each new directory, you have to open a new window with a list of folders and travel to the desired item, starting from "My Computer". In CloneSpy, everything is much more convenient: there is a special window for adding folders, which is divided into two parts: on the left, you select the desired directory, then click the Add Selected Folder button, and the directory is added to the list of folders to be scanned. You can repeat these steps as many times as you like without closing the window for adding a folder. And the list of selected folders can be saved for future use and, if necessary, loaded into the program.

The next feature is the output of search results as duplicates are found. In other programs, in order to see duplicate files, as a rule, you have to wait for the end of the scan, which, depending on how wide the search area is, can take a whole night. The results can also be viewed instantly - as the search progresses, the program opens separate windows for each group of duplicate files. In such a window, you can immediately run the file, open the folder in which it is located in the "Explorer", mark the files manually or, according to a number of criteria (date, number of characters in the name, length of the file path), delete or skip and go to the next group of duplicates.

The work with the program is somewhat overshadowed by the lack of the possibility of previewing images - it is very inconvenient to launch the program to view the graphics every time. If you are scanning a large area, then displaying the results in a separate window for each group of files is unlikely to be convenient. Therefore, in this case, before starting scanning, you should look at the Report tab of the program settings and change the parameters for outputting the results. However, by choosing the option to display the results as a single list, you will not be able to work with duplicates until the scan is complete.

Surely any of us on the disk over time accumulate duplicate files. Files in the "Downloads" that you downloaded several times, the same photographs and musical compositions, lying in such depths that they simply cannot be reached.

Hello dear readers. Today we will talk about duplicate files, as well as methods of dealing with them.

Based on the name itself, you probably already guessed what these files are. Duplicate files like these are very dirty on the hard drive, so you need to get rid of them periodically.

Duplicates appear on the computer randomly and due to user carelessness. Although we are all human and we tend to accumulate all sorts of things. No matter how much memory your hard drive has, after removing duplicates it will become much freer than it was before this process.

Unfortunately, it is impossible to delete duplicate files without third-party programs. For some reason, the Windows developers missed this point, but people found a way out. There are tons of things on the internet free software to get rid of duplicate files. Below I will list three of the best ones, as well as give you the opportunity to download them.

CloneSpy

A very simple and handy utility for cleaning your computer from duplicate files. After starting CloneSpy, it searches the files by checksums, ignoring the date and time of their creation, size, etc. This method of finding duplicate files allows you to make a more accurate and detailed search.

But CloneSpy also has a disadvantage, because in the search results, in addition to copies, it can display files with the same name.

Free download of the CloneSpy utility

Auslogics Duplicate File Finder

More powerful program for searching duplicate files. It makes a detailed analysis of the hard disk for the presence of duplicate files, at the end of which you will receive a list with all found duplicates.

I noticed that Auslogics Duplicate File Finder specializes well in finding duplicate multimedia files, which are gigabytes of identical music tracks, movies, pictures, etc.

Free Download Auslogics Duplicate File Finder

DupKiller

Also very good program to find and remove duplicate files. I really liked the function of setting the percentage of acceptable matches, which you can set manually before starting the analysis of the hard disk.

Hello Dear Friend.

When working with files and documents, we often do backups important data. In one folder in another in the third ... And then we even forget how many copies of this or that file we made and where they are stored on the disk.

As a result, free disk space is eaten away by unnecessary copies of files and folders. How can you find duplicate files on all your drives and delete them?

Everything is very simple, we will use a small free utility with Russian language support - Soft4Boost Dup File Finder.

You can download the program here:

After installing the program, the main window will open:

If we check the box next to "Ignore file names", then the search will not use the match of file names, the search will be performed by the internal content of the file. This is very important because the same files can be named differently. Fortunately, all the tips in the program are in Russian.

Below you can select the type of files to search for duplicates.

We choose required disks or separate folders (by clicking on the plus signs). Then you need to click on the image of the folder with the arrow to the right to add desired list folders to be scanned by the program.

In this window, select the method for deleting files. The first option is in the trash can with the possibility of recovery. Remember that the basket is limited in size. To increase the size of the recycle bin, go to the properties of the recycle bin icon on your desktop and set the size in megabytes.

You can also choose the option permanently, but I recommend deleting it to the trash first. If something goes wrong, you can always restore the file.

Press the button "Search".

After the scan is over, a window with the found duplicate files will open in front of you.

Select the files you want to delete with the checkboxes and click the button at the top of the "Fix problems" window, the selected duplicates will be deleted.

Like this in a simple way you can get rid of numerous duplicate files on your disks.

Of the minuses of the program, I would note the impossibility of viewing the found files by double-clicking the mouse. It would be very convenient to immediately view the file and remember what kind of file it is.
