Prev. Page, Next Page nav system... how to?

Hi,

Is there an wasy and quick way to implement a nav system like this inside a folder? I need to have this at the bottom of each page :

Previous Page, Backto index, Next Page

Wich would navigate through the directory tree by itself ?

thanks in advance,

Blaise

Forget it! Just found the PrevJumpNext Plugin! the dropbox is really nice!
