hborre, thanks for the folder chart, when I get my PC cleaned of the virus and reinstall all my programs I'll let you know and come back here to reference your images. What a day it's been!

You say that "extra" empty runtime folder in my screenshot (#1) is "not good", then why do you think the PoserPro2010 install program created it?

So, from looking at your pics, once I create a runtime folder on my external hard drive, I just have to go into the PoserPro2010 program itself and use the "add runtime" button to let poser know where to find my external hard drive directory that I created, is that right?

Another question looking at your directree, does your Victoria 3 folder also contain a runtime folder with all the same subfolders that you're showing in your V4 folder setup? In other words for each model's core folder, V2, V3, V4,M4, etc...each core folder has its own separate runtime folder within it, or is there only one runtime folder for all of the models, hope I'm making sense with the question, sorry.

If I'm understanding this correctly, each has it's own runtime folder and when you download and unzip stuff for V4, you tell the install program to send it to the V4 folder, and same for unzipping V3 stuff to V3 folder. I'm just confused about saying "yes" to replace the existing runtime folder, won't that also delete or or rather "replace" all the existing content in the subfolders that reside within the existing runtime ?  

I think Poser is a very cool program but it does have kind of a complicated filing system!
