That "cannot preserve ownership" message happens when you copy something TO /home/user/MyDocs, not from there. Rebhana told you to copy it from MyDocs to the new folders.

You won't see the new folders on your PC. You have to copy them to your MyDocs folder from the PC, then move them from the MyDocs folder to your home folder on the N900; that's why rebhana told you to move them with the mv command.

Make sure you are doing exactly what rebhana instructed you to do.
