@ Basicwiz: the OP title mentions PP2010.

Folders with 0 means that there is no content for that particular content under that category.  For example, if you load a pose file into Poser, you will see 0 if you are in the Character category in the Library.  Click the appropriate icon at the top, and you will see those folders populate.  If you are not sure which icon is associated to which category, please refer to the manual; it is clearly outlined there.
