Hidden Files

My 2GB Sansa Fuze has problems. I can’t view payday loansany of the mp3 files I put on it from my Computer.

I’m currently using MSC , because MTP/auto-detect aren’t detected from my computer.

Can some1 tell me how to access those files?(yes i can play them on the fuze, but cant see them from the computer)

Did you put the files on via MSC or MTP?
