This app is quite useful in finding and presenting duplicate files. I found the Duplicate MP3 Finder especially useful because I made backups of backups and didn’t know which files were my original, etc. I have purchased/used 1Tree, Duplicate File Finder and Duplicate MP3 Finder – all with great success. This is by far the best duplicate file finder I have found because of its easy use and method of filtering, I will most certainly be keeping this first-rate piece of software.

Other programs I have tried seem to take all day scanning drives/directories when you have a good number of photo or music files. If I had to mention one feature of these programs that I like best, and there are a lot of other good features, it is the speed with which the programs analyzes, highlights duplicates and allows you to delete. There are a number of similar programs out there to these two, but in my experience, these are the best. I am using about 6 of those licenses on 6 different computers all running Windows 10 (some Home, some Pro) and have not had any problems. I purchased 10 computer licenses to both Photo Finder and MP3 Finder about a year ago.
