Answer 2

The phrase "I get [an] error" is not at all helpful. If you're going to be using IT then it is really important to be precise. - What command(s) did you try? - What error(s) did you get? - What did you do to try and resolve the error(s) yourself? The command to move a file or folder is "mv", and you can read about it with "man mv": mv {from_name} {to_name} If this is what you tried but it didn't work for you, you will need to provide more details.
