I have a fairly large collection of music, some of which I have ripped at different times with different software. Through all my updates and additions to my collection, I have ended up with a mixture of file formats.
Through the magic of MusicBrainz, I have organized all my music into a Artist/Album/Title.fmt directory structure. What I want is to find files where Artist/Album/Title are the same, but .fmt (.mp3, .ogg, .wma, etc) is different. Basically, I want to get a list of duplicate songs that differ only by file extension.
If it makes a difference, I'm on Windows 7.
