I've got Steam installed. Steam is installed to c:\Program Files\Steam. Steam downloads various games to a sub folder called SteamApps. The only option available is for steam to download and install apps to the same location as steam. A typical setup could look like this:
C:\Program Files\Steam\SteamApps\common\Game1 C:\Program Files\Steam\SteamApps\common\Game2 C:\Program Files\Steam\SteamApps\common\Game3 C:\Program Files\Steam\SteamApps\common\Game4
My drive C is an SSD, so space is an issue. Game1 is very disk intensive, so I need it to remain on drive C, but I've got a terrabyte of space that I'd like Game2 and Game3 to be installed on.
Is there a way to create a virtual folder called "Game2" that really points to my bigger hard drive and to make it in such a way that Steam (or any app really) would be able to browse to the location on drive C and not even realize that it was really accessing drive D: where the virtual folder points to?
So in the end, C:\Program Files\Steam\SteamApps\Common\Game2 would exist as a folder but in reality it maps to D:\Games\Game2.
