Gigantic Hiberfil.sys in Windows 7

You’re reading this coz you have a tiny (40GB) SSD like me for the OS drive and there’s a gigantic (mine was up to 12GB before I had it removed) hiberfil.sys file and you want it gone to free up some much needed space? Fear not, this post is for you.

As far as I can tell, hiberfil.sys let’s your PC Hibernate, Windows will use hiberfil.sys to store it’s current state, and since windows is managing it, you can’t delete the file. Until you do the below steps of course.

Open up an administrator mode command prompt, and put this in.

powercfg -h off

You should immediately notice the Hibernate option gone from the shutdown menu, as well as, TADA, a bunch of free space on your C: drive (the file hiberfil.sys should also be gone from the root directory).

Note: I forgot to take screen captures of the process, sp yes you’d have to put up with a wordy post. Sorry.
