core function BOOKS

when i had my clipzip plugged into laptop, i meant to delete one book but by mistake deleted the file called BOOKS (like the sport, music,audible etc.files) …the entire thing… how do I get i back? the books icon/section still shows on the player, but there is nothing to drop/drag transfer my books to. should i just use the audible part?

i think i got it fixed.

For the benefit of others that may be searching for answers to the same issue, maybe you could post what you did to remedy it?
