I'm trying to figure out what you're doing, so I may seem to be asking stupid questions.

Content from DAZ3D was initially designed solely for Poser, then when they created Studio, for both applications. I can't think of a time I've seen anything that was only for DAZ studio-- although they do sometimes split the installation files into two separate files-- the one with the DS suffix is for Daz Studio, PS is for Poser. If you're using both applications, you should download both files because sometimes there are differences based, primarily on how the applications handle textures.
