Just looked at my C drive and saw that it was nearly full. My C drive is only 150gb but I have another drive that's 500gb. Was wondering if I could just copy my steam folder from C and paste it into D then delete the folder in C or if I would lose anything if I did this.
you will lose shortcuts and associated registry links, but if you launch games from steam like most people that wont be an issue, you should just have to relaunch the steam client once you have finished the copy
