In iTunes I have my "iTunes Media" folder set to /Volumes/MP3/MP3s. All of my music is stored there, no prob. But the "Mobile applications" folder somehow remains on my boot drive in Music/iTunes/iTunes Media/Mobile Applications. Is there an OS requirement that mobile apps must remain on the boot drive? Otherwise why are they not stored on the same assgined drive as my music? If I can move this folder how do I do that and not screw up my iPhone and iPad syncing?
