By usc:

sorry, missing some comments. and one is substring(length - 1), another one is substring(0, length - 1).
it's remove the end char of the home folder setting when it with the ‘/’ at the end .
e.g.
/mnt/sdcard/Music/ will be change to /mnt/sdcard/Music
if has the backslash at end of the home folder, it's has minor bug at "OperationUpLevel". pls check again.

so nothing should be modify.

Thanks.
