If you want to convert files from MAC to Windows or the other way the Mac drive 10 program that I mentioned does work. It also is free for 5 days. Is there a hook? Of course there is. It will only let you convert or copy 5 files at a time. So that means that it took a LONG time to copy and paste the 1240 songs on that Ipod into a windows folder. But I managed to do it successfully.
