I can't figure out where my Skyrim install directory is. Even after performing a proper search. Where does Steam hide it?

Where did you install steam? It will be in Steam/Steamapps/Common/Skyrim

Ah, and there it is. Really new to this whole Steam business. Thanks.

I found a directory junction* to help me keep track of Steam games.

E.g., my Steam is installed to D:\Games\Steam. But, I want my Steam games to show up in D:\Games as well. So the following command can be run in the cmd prompt:

mklink /J "D:\Games\Skyrim" "D:\Games\Steam\steamapps\common\skyrim"

This lets me see D:\Games\Skyrim as my Skyrim directory for all intents and purposes.

* = Directory junctions only work on the same physical drive.

Posting this here in case anyone else finds it useful.
