I've already used the iTunes Preferences Advanced tab to change the "iTunes/iTunes Music" folder to another disk drive on my computer. BUT, there does not seem to be a way to change the "iTunes/Mobile Applications" folder to be on another hard disk on my computer. I need to do this because the current drive is almost full. Does anyone know how this can be done?
It's easy, just move your ITL file to the other drive and start itunes from there.
The Mobile Applications folder gets put wherever the ITL file is. It will only affect FUTURE downlaods of applications. You'll have to move the older files to the new location and go back into itunes and tell it where they are.
