The only folders you can't rename are geometry folders. Poser must find the geometries in their original place. In some instances I've encountered trouble when I had the textures in the wrong place. Poser asks me to find the textures. I've worked with a runtime folder that is 10GB in size. Take it from me. You can rename every folder except Geometries. You can move all that other stuff around. You might want to remember where you put it!!! I've only opened a cr2 once or twice, and frankly there is too much techie stuff in there for me. Just use a file manager to do your work. ron
