i backed up all my files last week because i had to send in my PB in for repair. well i got my PB back an transfered all my mp3's to my PB. the problem was that the folders were sort of mess, so i just dragged some of the albums i had into iTunes individually. now i have a bunch of doubles in iTunes - and when i checked the iTunes folder, there are two different places where the exact same mp3's are. is there a way to eliminate the doubles - folder/files and in the iTunes library?
