MP3 Filename Oraganizer - Version 1.0 MP3 Filename Organizer is the ultimate program for renaming your MP3s and editing tags. Rename the files any way you'd like or update the tags with the most current information. It even has an intelligent algorithm for figuring out the information from the existing filename if no tag exists. It will even scan recursively through all subdirectories finding all MP3 files in a given path!
