Duplicate Music Files Finder (DMFF) is a freeware tool that can quickly and accurately track your music file duplicates and delete them.
It uses advanced search techniques to detect duplicates (it searches MP3s tags, detects duplicates even if the file names are not the same etc). Before deleting a file, you can even play them in your favorite Media Player to see if they really are duplicates.
The program offers 4 searching mode - file name comparison, file size comparison, CRC matching and advanced file matching (recommended for music files). The help file along with the tool lets you configure the tool very easily.
