Gained 17Gb in 10 minutes!
I had many MP3 duplicates because iTunes imported the songs and copied them. I was afraid to remove the duplicates manually because I was i doubt. This wondefrul app does not allow to remove MP3 that are in the iTunes folder, only files that are outside of it. I double checked randomly before and after the operation. It works amazingly! Bravo!
