Sansa Clip + 8gb - Folders not valid?

Has anyone been able to work directly on the Clip+? I can't open any of the folders, I get the message 'that folder name is not valid'.

It works only if the player is in MSC mode.

Thanks! Knew nothing of it before.

Here is some help for any with this problem:
