Thank you so much, EClark1894. I'm sorry that I didn't post a screenshot to explain the situation. I'm still away from my 3D computer; so, I still can't.

I'm familiar with Poser file hierarchy through Daz Studio and from buying and using content from Renderosity in D|S. Though my original post was unclear, I was trying to say that I was in my PC's file browser or Explorer or whatever Windows calls it. I hadn't even opened Poser. I would expect for a Poser product to have a Runtime folder that contained Geometries, Library, & Textures folders. But the files I've gotten from Cornucopia3D---though they are named "___ for Poser 6"---have no such folders in them. I did find a zipped application called "pz3 extractor," but I cannot find any information about it so far online. Perhaps it is for usage with Vue, which I do not own.

Thanks for taking the time to help me, and I apologise for my lack of clarity in explaining the situation.
