Cons
Con Out of date
Latest commit on Mar 26, 2018
Con Very Basic
It has basic features only. You can copy, paste, move files but no root explorer, SMB etc .
Con Does not support root yet
Con No additional features (suite)
No other features such as networking connections, junk flies cleaner, built-in media player/viewer/editor. But that might be a pro, since nothing else is asked for this app permission.
Con Outdated
At this moment I'm writing, it was updated last in 2017.
Con Ugly UI
The GUI is old and deprecated. But what would you expect for such a small app?
