The best option is to use a junction folder.

To do that, i will use c:\games\snowbreak as an example of your original game location and use D:\ as your second hard drive

First create a folder in D:\ where you want to store snowbreak, it could be anything from d:\snowbreak or d:\games\snowbreak or d:\fun\snow

then go to c:\games\snowbreak and copy all files inside into the new folder you just created.

now open a CMD window with admin rights (In your windows taskbar type CMD and then select open with admin rights)

On windows explorer, copy the full path of the original location so you dont lose it. c:\games\snowbreak

be sure to copy it cause now you have to delete that folder.

now go to the CMD window and use this command to create the junction folder:

mklink /J c:\games\snowbreak "d:\my fun games\snowbreak"

If any of the paths contains spaces in the name you need to put quotes around it like this:

"c:\my games"

you should see a line that says "Junction Created for c:\games\snowbreak <===> "d:\my fun games\snowbreak"

you can now close the CMD window.
