Yes Tim, that's exactly what you do, you just don't need the UI and pref's and any actual program related subfolders that tell Poser how to operate. Poser 6 has those subdirectories already in it's main runtime and they're wasted space in any external runtime.

All my external runtimes are now on an external fire wire 250 gig hard drive I just bought. I got way to close to filling up my system drive. LOL! Now I can download for another 20 years worth of freebies!
