That link shows where the files go. Sometimes with new items made for poser 6 you will find the .obj file in the character folder instead of the geometries folder. If that happens, just leave them there. As for the character addon you bought, I'd recommend unzipping it to a folder on your desktop and making sure the files are in the right folders according to the above linked image. Once you have checked to make sure that the files are in the proper runtime structure, you can drag and drop the Runtime folder into your Poser 6 folder. NOTE: That's if you have a PC. For MAC users, don't drag and drop!!!

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
