I'm still using Poser 6.  There's a lot of old content rattling around in my Runtime.  Not sure about the RSR files.  I know some just contain (obselete) thumb information but thought some of the rsr files were nessessary.

I've kind of settled in with the Runtime I developed some time ago.  I don't make too many changes to the texture or geometry folders and moving the library files isn't that big of a deal.  I've also backed up whole Runtimes to an external drive.

One thing that bothers me about version 6 -- and I'm pretty sure Poser 7 fixed the issue -- is that geometry has to be the Poser/Runtime folder.  You make sets of Runtime libraries but Poser 6 (and earlier) will always seek the .OBJ files in the primary Runtime.  Textures maybe recursive -- the files don't have to be in a stick place -- but geomtry does.

I kind of wish they'd have just have put the .OBJ files in with their CR2s or prop files in the libraries.  I know when you use the python script to inventory AND COPY FILES TO A FOLDER things work great.  Maybe I should just backup whole scenes I like to use and whole characters to their own folders ...

I ramble.  Thanks for the thread.
