Ok so I recently got a new motherboard and used the same hard drive that i used before. I installed windows on my new ssd but i forgot to wipe my old hard drive that i used for my old motherboard and windows. So now im stuck with 500gb of space to use on my hard drive and the rest taken up by old game files from steam on my old windows 8. Is there a way i can delete those old files and keep my new ones without messing anything up?
