actually, if you just show hidden files, then you can access the files directly on the ipod. they're all there. just in hidden folders, named 01, 02, 03 etc, up to possibly 50 folders.
in those folders are all the songs on the ipod, split at an average, renamed and striped. this means that an album will go onto an ipod, where the 1st song goes in folder 01, and named as 01.mp3. the second song goes in folder 02, and named 01.mp3. further along the line, the 10th song on the 100th album goes into folder 36, and named as 32.mp3, for example. so it's actualy a terrible pain in the arse trying to find specific music, so you may as well pull all the songs off.
