Please check following things first:
-Goto My Computer properties > Advance System Settings > Performance > settings > advance and note the Total Paging size fro all drives. This size is also used on C drive by default.
-Hibernation also takes same space on C Drive as the size of your installed ram. You can turn off Hibernation by cmd> powercfg -h off

Plus if used space is continuously increasing, you should scan your pc for malware.

I ran this command and it worked(gave me 6gb). Wouldn't it affect my pc perfomance or any other issue with ram or something??? lag ? anything?? what purpose of hibernation?
