A single corrupted music file should not affect the entire folder. If your issue is with a file that says something like complete album then you can't save anything in that file. So if the first song is corrupted then all songs in that album would be inaccessible. I've tried to find a way to disect some of these corrupted files and find it is faster to just find another file. Sometimes this means finding all the music individually. Depending on the file type you might try a hex decoder and try and break down the individual strings but as I said this I did as an experiment with about a 5% payoff for several hours work. It is easier to take your lumps and locate another copy. (I tried this on Windows XP OS - incase you can retrieve on MAC OS so please don't send me 60 gazillion hate letters!) -- Best Of Luck
