How to delete Audible folder in Audiobook.

Okay, the subject pretty much says it all. Does anyone know how to permanently delete the Audible folder in the Audiobook folder of a SanDisk Clip Sport 8GB MP3 Player? I already tried deleting the folder when I had my MP3 connected to my computer, but once I check the MP3 screen, the Audible folder is still there. Any solutions?

I don’t have an Audible folder in the Audiobook folder.

I do have an Audible folder directly on the root and have no problem deleting it permanently.

However, my clip sport persist on recreating it once deleted, so the problem I guess is not  how to delete the folder, but how to prevent it from being recreated.
