great, that's exactly what I was asking, Thanks Hborre.

I'm not sure I understand the texture and geometry thing though. Would I need to hunt through those existing folders to find the relevant files to transfer to the new runtime. Say I copy some characters that have been setup in Runtime A to Runtime D. Would Runtime D need the Geometry and Texture files copied as well or would they read them from the original Runtime A?

I already have a few Runtimes but with this project in particular I'd like to move just the files I want to use. Would I need to move all the !V3, !M3 injection files as well or will they sit and get accessed quite happily remaining where they are?
