P3DO comes close - the problems with an uninstaller would be: more than one .??2 file may refer to the same OBJ or texture (all the Poser 4 Male Characters and Female Characters call the same geometry as Posette and Dork, you probably have multiple M/V1 chars. calling their respective geometries, lots of free V&M textures call the default lash and brow trans). there's no ready way of reading which character or outfit a pose file is for, so if you zapped the CR2 and support files the MATs would be left behind. people move stuff around, which would kill a history based uninstaller.
