QuoteI purchased 10 computer licenses to both Photo Finder and MP3 Finder about a year ago.
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.
There are a number of similar programs out there to these two, but in my experience, these are the best.
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. Other programs I have tried seem to take all day scanning drives/directories when you have a good number of photo or music files. - By John User for Duplicate Photo Finder Plus & Duplicate MP3 Finder Plus
QuoteThis 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. - By Tata for Duplicate File Finder Plus
QuoteI have purchased/used 1Tree, Duplicate File Finder and Duplicate MP3 Finder – all with great success. I found the Duplicate MP3 Finder especially useful because I made backups of backups and didn’t know which files were my original, etc. This app is quite useful in finding and presenting duplicate files. - By Kyle for Duplicate MP3 Finder Plus
