EmptyPockets :
Awesome, thanks! Also: I was wondering, since I never figured out how to do this, if it is possible to make it so that nothing ever goes on my boot drive other than Windows updates. I know a lot of programs (games for example) will save files in Program Files or My Documents, which is by default on the primary drive, but is there any way to make it so that all those folders (Program Files, My Documents, etc.) are on a secondary drive and nothing ever gets written to the primary drive? (It's a pretty small SSD and I don't want it getting cluttered up).
"My Documents", easy (its not 'My Documents' anymore....but various folders under 'Libraries').
Create some location on the HDD target drive:
My Stuff....under that MyDocs, MyVids, MyMusic, etc.
Right click on Documents in Libraries, select Properties
Here you can designate a new location (that which you made above) and set that as the default save location
For applications, on installing something, select Custom or Advanced. You can choose specifically where it goes.
For Steam and Origin games you can designate a default location in Settings. Choose where you want.
"Nothing ever goes on the boot drive" ? No, not 'nothing ever'. But minimal.
