is it possible to make a script or batch or something rockbox that allows renaming of files on the device itself? i know renaming could be done itself with the keyboard itself.
i was thinking if this was possible a quick batch rename of the mi4 file (for the iriver h10) could be renamed to something else and the original mi4 file to it's original name to switch back to the default firmware.
of course this only works one way, so renaming back to rockbox would still require the a computer.
