So you've got your fancy new SSD and your machine boots in 2 seconds, but what about your games?!
This is a tutorial for moving individual games to your SSD (or any other harddrive) without moving your entire Steam/Origin install.
The magic behind moving a specific game directory to a different drive in Windows is the MKLINK JUNCTION command.
Create a folder named "Games" on your SSD. Putting the folder in the root of the drive will make it easier to run the commands later. Example: "D:\Games"
Locate your Steam install folder.
Windows 7 64-bit - C:\Program Files (x86)\Steam\
Next, locate \steamapps\common\ in your Steam install folder. This is where 3rd party game installs are kept in their own folders.
Select the game folders you wish to move and then select CUT.
Go to the "Games" folder created in step 1 and click PASTE. This will move the folders and files for each game over to your SSD and remove them from the original drive. The next step will link these moved folders back to their old locations so that Steam can find and use them.
Open a command prompt.
With the prompt open, use the mklink /J command for each game that you moved. The mklink command creates a link to the moved folder. The syntax is as follows:
mklink /J "link" "target"
mklink = the 'make link' command
/J = the junction prefix, which creates the link between folders
link = the file path to the folder that needs to be linked to
target = the file path to the folder that has the data in it
Example using Skyrim on Windows 7 64-bit:
mklink /J "C:\Program Files (x86)\Steam\steamapps\common\skyrim" "D:\Games\skyrim"
*It is important to note the quotations used around the file paths, as the command line does not like spaces or special characters
When this completes correctly, you should see:
Junction created for C:\Program Files (x86)\Steam\steamapps\common\skyrim <<===>> D:\Games\skyrim
