How to Delete hiberfil.sys and Recover Disk Space on Windows

Desktop computers rarely need to hibernate, so you can probably safely remove the hiberfil.sys file and save yourself a few GB of space. To do so, just open up a new command prompt as an administrator:

  1. Click on the Start button
  2. Type β€˜cmd’ (don’t hit enter)
  3. Right click on the Command Prompt that comes up and choose Run As Administrator.

Once you have an administrator command prompt up, just run this command:

powercfg.exe /hibernate off

Now check your disk space again and you should see the hiberfil.sys file is gone.
