If you are reading this, maybe you have problems with your storage as a gigantic file named Hiberfil.sys occupies most of your free storage. Maybe you are wondering if this file is a virus or if you can even delete it.
Windows has a feature that lets you hibernate your computer to save power when you are not using it but don’t want to turn off your system completely.
Hibernate allows you to retain all your system’s current progress, including all the running applications on your computer. It conserves power by writing the information in memory to the hard drive and shutdown itself while saving all your progress.
This is where the large hiberfil.sys file comes into place; it is created by your Windows operating system to store the current state of your computer before going into hibernate mode.
In this way, the computer can startup faster and restore all your progress after coming out of hibernation instead of booting up Windows again when you shut down your computer.
Hiberfil.sys is normally hidden on the file explorer, and the only way for you to see it is when you enable the “Show Hidden Files” option on the Windows File Explorer.
In this case, if you don’t want to use this feature already, as it takes up a lot of space on your hard drive, we will show you how you can get rid of the large Hiberfil.sys file on your computer.
