beegle writes "I want to store all of my CDs as FLAC. I really want this to be The Last Rip Ever. Getting the data off of the CDs is easy with abcde on Linux or EAC on Windows. My problem: I have hundreds of CDs. How do I organize the rips to make future conversions to the format du jour easy? Are there any programs out there that can walk a directory tree full of flac files and convert them to mp3, aac, ogg, etc.?"
