OT: file management is one thing that "if you need to learn one thing on the command line for linux, learn this"
The associated commands like ls, mv, scp (et al with wildcards) are very efficient when understood even partially.
The GUI is basically an implementation of only part of the capabilities of the command line and all the goodies are usually left out.
Just remember, on the command line "silence is success" but it will do what you tell it to do, which might not be what you want.
