I have recently started to re-rip most of my music collection in flac but as a result I am ending up with many duplicates. I have found many programs such as MrClean that find duplicates of songs but I do not want to accidentally delete the high quality mp3's or flac files. Is there any program that can do this for me? I would prefer it free but I would be willing to pay 10 dollars or so if the program is legit. Thanks.
