I just realized that iTunes* went crazy at some point in the past year, and I have two or three copies of about half of my music collection – all in the same folder as the originals, but with different filenames and metadata. The apparently random nature of which files were copied and how many copies I ended up with makes it less than convenient for me to go through and clean the folder up manually.
Is there a program that can search through and identify the duplicate files, even accounting for the differing metadata, and allow me to bulk-delete them? I’ve tried MediaMonkey and Duplicate Music Files Finder, and they both seem to choke on the different-metadata problem.
* I assume this to be iTunes’ fault because it is the only media player/organizer that I have ever used on this computer.
