Downloading enviroment and materials

Hi! Everyone
I have Rhino with RhinoGold 5 and Brazil for Rhino.
Trying to use the Brazil render. I’ve download enviroment from food4Rhino but don’t find it from Rhino. when I try to open the downloaded file and got open by Photoshop.
How do I find and use it from Rhino and Brazil?
Thanks
