About WRITE , DELETE (Directories).
Delete Directories is not so easy. As most Dirs are protected. Since months… Security issues from handset/Firmware.
Today realized that maybe Samsung imroved Security in JL2 to prevent replace of files… Maybe also App Data like Savegames…
Not sure, only idea. Because today I was not able to delete package_general.bar from Asphalt 5… 😯
I have no idea, if this also for DATA folder with "myfile.my" would fail if I try to copy myfile.my backup to Wave.
