A program that searches for similar files. Finding and removing duplicate files using the program - Auslogics Duplicate File Finder
Hello Dear Friend.
When working with files and documents, we often make backup copies of 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 up by unnecessary copies of files and folders. How to find duplicate files on all your drives and delete them?
Everything is very simple, we will use a small free utility with support for the Russian language - 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 a match of file names, the search will occur by internal content 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.
Select the desired disks or individual folders (by clicking on the plus signs). Then you need to click on the folder image with an 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 with the possibility of recovery. Please note that the size of the basket is limited. To increase the size of the recycle bin, go to the properties of the recycle bin icon on the desktop and set the size in megabytes.
You can also choose the option to permanently, but I recommend deleting to the trash first. If something is wrong, you can always restore the file.
Press the "Search" button.
After the scan is over, a window with found duplicate files will open in front of you.
Select the files you want to delete with checkboxes and click on 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 look at the file and remember what kind of file it is.

A program for finding duplicate files is most often needed by users who store on disk a large number of music, photos and documents.
And, although you can delete such extra copies manually, specialized applications can save a lot of time.
Especially if the files are located in different folders or in hidden directories. 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 in different photos is practically equal to zero, the same values are considered a sign of a duplicate.
Sometimes the algorithm provides for checking names, which is also an important parameter for searching, especially since the same data in most cases matches the name.
The advantages of the programs are the ability to find files of any type with their help and the relatively high speed of work. The disadvantage is the lower accuracy of detection. So, for example, none of these utilities will consider the same photo saved with a different resolution as a duplicate.
1. DupKiller
An application that searches for files with almost any extension can be downloaded for free on the official website of its manufacturer.
Among the differences of the program is the interface in Russian, fast work and a large number of settings.
With DupKiller, you can compare files by size, by date, and by content (the latter feature is supported only for certain types).

2. Duplicate Finder

For the convenience of users, the utility settings allow you to search by size, by checksums, and by name.

Although the comparison of information by default occurs by file names, so it is advisable to change the settings immediately. But in the process of searching, each found duplicate can be viewed without closing the application.
And if a copy is found, it can not only be deleted, but also renamed or moved to another location. Additional benefits of the application include a Russian-language menu and completely free work for any period of time.
In addition, the manufacturer also releases a portable version in order to look 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 (while updates for Linux and MacOS appear regularly).

Search for duplicate audio files
If the results of the search for duplicates do not suit the user, you can consider an option designed for certain files. For example, for music accumulated on a disk.
Such a need often arises when loading several albums and collections of the same artist at once - often the same tracks appear 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 a relatively fast search and good efficiency. In fact, this application, as it were, “listens” to the composition and compares it with other audio files.

At the same time, photo analysis also takes longer than searching for files of any extension, but the result justifies itself.
Images are determined 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 are checked - from .jpg to .png.

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

conclusions
The advantages of programs for finding copies of files are serious enough that at least one of them should be installed on every computer.
Especially if the user is constantly downloading from the network various information. With the help of utilities that detect duplicates, you can save more than one hour of your time and several gigabytes of disk space.
One of the most quick ways Score HDD- storage of duplicate files. Surely many are not even aware of their existence ... they may have different origin: random copies, many identical downloads, and so on. One thing is for sure - they can really create some problems for you.
A lot of duplicates are created because of the need to keep the file "safe"... for example, before editing a document, I could make a copy just in case, and then forget it... or I already have such a document, and I downloaded it again from the mail. Unfortunately, there can be a lot of such doubles and it turns out that you score free place useless information.
With these tools, you can figure out and remove duplicate files in minutes and free up a lot of valuable hard drive space. I will only consider free utilities so you have nothing to lose!
Search for duplicate files. Overview 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 labeling and selection algorithm.
What are non-clear duplicates? Several identical files may have different name. For example, you may have two files on your computer: example-file.avi and example file(1).avi- the utility understands this very well and can also mark them as a duplicate.
By the way, the utility also has other editions: Music Edition and Picture Edition, optimized for finding duplicates in 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 work is to enumerate all the files on the computer by size and compare them by content. On the one hand, this is logical, but it is quite sad for video and graphics. (after all, depending on the compression algorithm, they can have different size) , but for everything else the program is just great.
Thanks to this comparison algorithm, Duplicate Files Finder is much faster than its competitors.
AllDup is a powerful duplicate search tool created by one person, 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 more different parameters.
AllDup has many useful features and great flexibility in terms of finding duplicates, but you have to pay for the functionality. The interface here is not at all friendly and this can drive an insecure user into a dead end. However, if you can figure out the program, then this application will be a good tool for finding duplicate files.
Duplicate Cleaner requires fine manual settings before you can use the functionality of this program to one hundred percent.
At manual setting 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 create shortcuts to the only necessary file instead. In general, 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 be more than ever for you. Images are, in my opinion, 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 their number, I have no desire to deal with them manually.
The program has flexible settings and can detect inaccurate duplicates - this is especially true due to the presence of artifacts that appeared 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 remove the duplicate.
Conclusion
All as in real life When 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 cleaner programs will not find them - as they are legally found on the hard drive.
