Default scenery on disk ?

I have a slight problem. I have tried a global scenery upgrade, and while things do look better for the most part, my frame have taken a HUGE hit for the worse, and I want to reverse what I did.

I installed it to a temporary folder so that I could pick and choose what files i wanted to install.... so, UNINSTALL will not work in this case.
I need to know ... on what disk are the DEFAULT SCENERY files located on? or.... am I just looking at a uninstall / reinstall???? If you say uninstall... im gonna slap someones post back to their firewall. lol
