As an audio/music pro with a macbook, it is crucial that I not waste precious disc space on redundant, duplicate files. Sometimes files will have different names, but have the exact some contents. Sometimes I won't know which files are newest, or which version to keep. I found Chipmunk after searching VT for "remove duplicates". I gave it a try, liked it very much, and bought it.

Chipmunk allows me to choose locations or sets of folders to scan for duplicates. It creates a list of duplicates, and allows me to get rid of them one-by-one, or as a batch. There is an organized way the Chipmunk allows you to get rid of duplicates outside of, or inside of the current folder.

Because I have tons of samples in my instrument libraries, and audio files in my iTunes and elsewhere, Chipmunk had a pretty clever way of managing the data. I got a ton of space back on my macbook. I imagine this utility will be a great help for anyone with large numbers of iTunes tracks and photos.
