There's a limit of 256 folders in any library. But before you reach this point, Poser starts truncating the names as you've seen. There are a variety of solutions: Upgrade to Poser 5. ;) Remove folders you don't really use - just move them somewhere else on your disk so Poser can't 'see' them, then you can replace them. Check out a utility called Pbooost which facilitates the process mentioned above. Put some of your poses in the camera library, renaming the extension from pz2 to cm2. They'll still work.
