Do you know how to increase my C drive without deleting some important data or programs? In fact, yesterday, when I attempted to install a newly download program, a message popped out and told me there was a low disk space problem. I had also checked my C drive space. There was really 597MB of free space left. So, I just want to increase this drive successfully. Do you how I can do that? Any advice could be greatly appreciated here. Thank you!
