In this post I’ll look at how to delete the Hiberfil.sys file from your computer.
If you are reading this then you are probably trying to free up some diskspace on C:\ and have noticed you have a large file called Hiberfil.sys.
The Hiberfil.sys file is a file that Windows uses to write the contents of memory to when you ask your computer to Hibernate. The more memory you have in your computer the larger the Hiberfil.sys file is likely to be.
If you’ve tried to delete it already you’ll have seen the following error message:
So before we can delete the file we need to disable Hibernate.
Click Start, and then type cmd.
Type powercfg -h off and hit return.
