This is the best and when i say the best i mean the best file manager you can have on android . Like it has everything a good file manager should have and is really stable . I don't think i have ever been more impressed by a piece of software or promoted it as much as i do this . All i am saying is it is the peak for android it has various compression/extract options built in can work with root , have a text editor . Etc. Etc . No file manager i have used ever has even came close .
