After relocating your application directory (manually, or with
BossTool) some packages are installed into root. (as opposed to the
mobile directory)
Using an SSH program: (for example, CyberDuck)
To correct this, these files must be moved from [example]
private/var/root/Media/EBooks
To
private/var/mobile/Media/EBooks
Same for
private/var/root/Media/ROMs
(Frotz, PDF, other folders, at this time, leave alone.)
