My computer is constantly switched on, and today I was checking if I had any files which I could delete. I was doing so becuase my computer is running a bit low on disk space. I had the view hide protected and system files option off in the windows explorer options and I noticed a file named Hiberfil.sys which is the file used by Windows to support hibernation.
I decided to remove this huge file since I never use hibernation, and all that is needed is to run the following command from an elevated command prompt :
powercfg.exe /hibernate off
The Hiberfil.sys was gone and I had a couple more gigs of disk space.
