Transfer music from one clip to another

I purchased a Sansa Clip a couple years ago and loaded 1,300+ songs on it . A friend just bought the same Sansa Clip. Is there a way to transfer the music from my Clip to theirs?

Plug clip into the computer, copy files off. Plug new clip into computer, copy files on.

is there way to access the files on a mac computer?  my mac computer detects the sansa clip as external drive, and shows the music   folder etc. but when I open the folders they are blank.  I can drag songs to the folder, but do not know how to access the music files on the sansa player to drag onto my desktop or itunes.
