I have a rooted tablet and while browsing my files, i came along this folder: (./0/android/data) in the internal storage ... lets say (X-plore file browser) has the folder: (./0/android/data/x-plore).
For some reason, i wanted to change the permissions for that program, instead of giving it the permissions: (reading, writing, executing) ... it will be (reading & executing).
The problem is it says (process failed, some file systems do not allow changing permissions) using Root browser or ES File Explorer (both with root access).
1- Why it says i can not change permissions although i have the root access already ?
2- Why it refers to a folder of an external application [(./0/android/data/x-plore)] as a system file ?
