Last September I took the plunge and switched from an old unstable Windows box to a brand spankin' new mac pro. In the process, I moved gigs and gigs of old music files. I was actually very methodical in my cateloging on my old machine creating folders like "My Music A-D" and then subfolders under that for each artist and then a subfolder under the artist for each album with the songs in that. When I moved these folders to the Mac, I put them into the Music area so now when I open that up in finder I see iTunes, GarageBand and my assortment of folders. When I started using iTunes I think it searched the system for my music and imported them into the iTunes folder. My question is, do I now have duplicate of all my music living in the iTunes folder and also in my old folder structure? If so, can I free up the more than 80Gigs of space my old folders are taking up by deleting them?
