How to Disable Hiberfil.sys

The one thing that every computer use fights for with their computer is storage space. No matter how large a hard drive your computer has, they always seem to be running out of storage space, which is why they want to maximize the amount of free space their computer has to offer to them by clearing out any and all junk files stored on their hard drive. The average user wants to get rid of the largest unnecessary files first, which is what brings their attention to a certain hidden file in Disk Drive C that is stored under the name of “hiberfil.sys”. Hiberfil.sys is only visible if the Windows Explorer settings on a computer are set to display hidden files and folders or if you type “C:” into an open tab on an internet browser.


Hiberfil.sys is a system file designed to aid the hibernation mode feature. Everything stored on a computer’s RAM when it goes into hibernation is copied onto its hard drive in the form of the hiberfil.sys file. When the computer wakes up from hibernation, all the stored data can be accessed at light speed, allowing the computer to boot up almost instantly.

The size of the hiberfil.sys file, in most cases, is almost as much as the size of the computer’s Random Access Memory. The Hiberfil.sys file can definitely be deleted, but whether or not you should delete it depends on whether or not they plan on using their computer’s Hibernation feature. If you do not intend on using their computer’s Hibernation feature and wants to get rid of the hiberfil.sys file, all they need to do is turn the Hibernation feature on their computer off.
