Ok, so here's the dilemna... When I first bought my PB G4, I created a Music folder on my desktop. Within the folder are 8 sub-folders of mp3's divided by genre. This is the type of setup I had on my PC. Unbeknownst to me, Itunes created its own Itunes Music folder where it stores a copy of all my mp3s. (I only use Itunes for playback.) Now I've discovered that there is an overlap between the MP3s in my Music folder that sits on my desktop and the MP3's that are in the Itunes Music folder. What would be the best way of cleaning up this mess such that I'll only have one copy of each mp3?
