Hi, Originally I have a ITune Music folder in the internal HD of my iMac, and I copied the whole folder to a NAS as a backup. Recently I bought a new PC (actually a Mac Mini but I just want to run Windows XP) so I would like to have both computer accessing the same songs, so I changed the iTune Library to point the the iTune Music folder in the NAS. In may iMac, I did: 1. Selected all the songs in iTune Library and deleteed them 2. in the Preference->Advanced, changed the iTune Music Folder to the NAS location. 3. In File -> Add to Library, selected the NAS folder Should I do the same with my Mac Mini? If later I rip CDs with my iMac, songs will be added to the NAS, but how to reflect or sync this change so my Mac Mini's iTune library also has the new songs ripped from those CDs? Is there a way to refresh the iTune library of my Mac Mini? Thanks for your help.
