File system rights has little to do with rooting. All that is rooting is not something I can write in this small space but file/folder permissions is not about rooting.

Rooting can help in removing unwanted apps but rooting does not mean these apps will show up in Android Manage Apps control panel. Sometimes you have to change folder permissions, edit arcane files and more to blow away an app.

-> Get to a forum that does rooting all that time like XDA Developer and be careful. That is, if you demand answers they will not answer or flame you. There's a lot to learn and it won't fit in this small text space.
