yeah just double click 'em, they are slightly improved versions of the default don and judy! if you haven't opened poser and click 'em they will open poser for you and load that character,otherwise open poser and "import poser character or prop" and locate your pz3!! i remember some kind of issue with them though!! they either messed up some lights or had trouble locating part of the texture,can't remember what it was though, and it may of been fixed by now. I keep my character and scene pz3's in a folder outside of poser by the way.
