I need more than a reboot

I have deleted everything in the MUSIC folder, PLAYLIST folder, even deleted all pics, but when I turn the unit on, several playlists are there, and when I try to play a song, it freezes.  (Because the song isn’t on the unit.)

I rebooted (pushed button UP for 30 secs) and they are still there.  I am just trying to start from square one…  Anyone else had anything like this?

Try reformatting.

Settings>System Settings>Format

Thank you.  Worked like a charm.
