Here is a list comparing the main software packages available for deleting duplicate files on a computer. Most of them can only delete images, but some can delete audio files or even videos!
The list includes around twenty software packages, all of which have been installed and had the same test protocol. In order to remain as objective as possible, I used a point system to provide a ranking.
Number of binary files: 107017 including 37373 duplicates
Number of photos: 8152 including 20 duplicates
Number of music files: 897 including 20 duplicates
Number of videos: 72 including 5 duplicates
Test environment: 6-core processor and SSD disk
(+10 if the function is present and fully functional): Binary file analysis +10, Photo analysis +10, Video analysis +10, Audio file analysis +10, Managing a memory cache +10, 64-bit version +10, Integrated duplicate view +10, Real-time results display +10, English version +10.
Analysis of the results:
The Duplicate Media Finder software is the clear market leader https://duplicate-media-finder.kdo-rg.com. It is the only one that can find all types of similar files. It is also extremely fast. In addition, it displays all the duplicates found in the form of thumbnails, which is extremely practical. However, this obviously comes at a price!
There are other software packages that I also liked and that you can find at the top of the table. Feel free to use them if they meet your needs.

|Opinion||The most complete software package available is definitely the most useful. https://duplicate-media-finder.kdo-rg.com||A great software package. It’s a shame that it doesn’t detect binary duplicates. http://similarity-app.com||The best available if you only want to detect video duplicates. https://www.video-comparer.com||Small issues. Visually superb but a bit slow. http://duplicate-files-fixer.com||Great if you are only looking for video duplicates.||Has a module for audio but only compares tags.||The Windows version is no longer in use.||Great, but a bit slow.||Good duplicate detection, but does not offer a detection threshold setting.||The interface is fantastic, but the test stopped before the end because too long.||Rapid software, but the management of identified duplicates is not very practical.||You have to change too many complicated parameters, to get an uncertain result.||Good, but you need to buy a license every year.||Managing identified duplicate (deletion) is not practical.||The binary comparison is only bit-by-bit, which is extremely slow. The photo detection works but is also very long.||Small problem during installation that was quickly solved. I had to install it on C: Pleasantly surprised by the original presentation of the results in the form of a tree structure.||Slow and very difficult to operate. Very few options find many duplicates.||Finds the binary duplicates but is very slow.||No statistics on duplicates found. Even if duplicates are displayed in real time, you cannot scroll through the results until the end.|
