This is not true with all poser stuff. The majority of stuff which i've bought you can not just rename the file without re-editing the files to make sure everything is pointing to the right location. I've spent well over 8k on models/textures for poser and the larger majority of stuff can not be moved without editing each file because of the way it was packaged. There should be stricter guidelines for merchants far as packaging and obj's being placed into the geo folder but this would have to be a 'community' thing across sites with so many new poser comunities popping up.
