MEMORY SAYS IT IS FULL ON THE MP3 PLAYER BUT ON MY COMPUTER I DELETED ALL OF THE FILES OF SONGS AND WHEN I GO TO HIT TO SEE IF IT IS FULL IT SAY 99.9 ON IT. SO HOW DO I DELETE ALL OF THEM ON THE PLAYER ITSELF? WHEN I PLUG IT IN THE COMPUTER IT ALSO SAY FULL WHERE I CANT ADD ANY MORE TO IT BUT YET ON THE PLAYER ITS STILL SAY NO FILES UNDER THE MUSIC PART.
