Disable Hibernation File Windows

You’re no doubt reading this article because there’s a huge hiberfil.sys file sitting in the root of your drive, and you want to get rid of it to free up some space.


The more memory you have in your PC, the bigger the file will be. Windows has two power management modes that you can choose from: one is Sleep Mode, which keeps the PC running in a low power state so you can almost instantly get back to what you were working on. The other is Hibernate mode, which completely writes the memory out to the hard drive, and then powers the PC down entirely, so you can even take the battery out, put it back in, start back up, and be right back where you were. Hibernate mode uses the hiberfil.sys file to store the the current state (memory) of the PC, and since it’s managed by Windows, you can’t delete the file.


So if you never use it, and want to disable Hibernate mode, heres how.
Disable Hibernate (and Delete hiberfil.sys) in Windows 7 or Vista.
You’ll need to open an administrator mode command prompt by right-clicking on the command prompt in the start menu, and then choosing Run as Administrator. Once you’re there, type in the following command: powercfg -h off


You should immediately notice that the Hibernate option is gone from the Shut down menu.


You’ll also notice that the file is gone from the hard drive.



Disabling Hibernate Mode in Windows XP
It’s a lot easier in Windows XP to get rid of Hibernate mode. Open Control Panel –> Power Options, and then find the Hibernate tab.


Uncheck the box, reboot your PC, and then you can delete the hiberfil.sys file.
