My old M240 had an Audible folder into which I stored music file (no music folder). I had a 4gb clip for a short while and that had a music folder but I don’t recall seeing a folder named Audible, but I could be mistaken.
My 8gb has both a Music and an Audible folder. The latter is supplied by the firmware (latest 2…32a), I’ve deleted it but it comes back. I haven’t used it, why is it there?
