All my textures are in a "textures" folder and they stay there because I don't want to have them duplicated in every program folder. As for objects, I have a "3d objects" folder too, with subcategories for 3ds, lwo, vob, etc... My Poser pz3 are in my Poser folder, because pz3 is not a 3d file format but a Poser scene format. Same for .vue scene files.
