Well its tricky but it can work. You can use the MKLink Command.
MKLink Creates Links from a Location to Another. You can basically move a "NON-Critical" Folder or even some Default Installed Windows Programms to your HDD and Link these folders from your SSD to HDD.
So basically your System will think that they will be on C:/ but they will be on D:/ or whatever letter is your secondary drive.
