Rhino previewer

Years ago I downladed a previewer which showed a small image in the folder when I selected a Rhino file. This way iit was easy to see what CAD was in the Rhino file.

I just updated to a new computer and do not have this previewer on it. Does anyone know what the program is?

this help?
