Keep the textures in the texture folder and the geometries in the geometry folder. The files in the library folders characters (cr2), poses (pz2), materials (mt5 and mc6), hands (hd2), heads (fc2), hair (hr2), props (pp2), lights (lt2), cameras (cm2), and scenes (pz3) can be moved into any of the library folders. And scenes don't have to go in any runtime if you don't want to use the library to load them.
