So I was using Itunes, and accidently made a ton of duplicates. All the good ones were names whatever1.mp3 thisisafakename1.mp3, and the bad ones whatever.mp3 and thisisafakename.mp3.
I see you have the option to get rid of all the *1.mp3's, but what about the opposite ones? Like getting rid of the ones with NO 1's in the title.
