What is Hiberfil.sys? How to delete Hiberfil.sys?

One of the ways to increase storage capacity on Windows  is to turn off hibernation mode, reducing the space used by the Hiberfil.sys hibernation file. When you enable hibernation mode on Windows, the system will transfer your open applications and documents to the Hiberfil.sys file to save and start immediately when we need it. Below are instructions for deleting the Hiberfil.sys file.

What is Hibernation File in Windows?

The hibernation file is called hiberfil.sys and Windows uses it to store the current state of your PC. When you hibernate your PC, Windows moves your open applications and documents to this file. Then, when you turn on your computer, the system loads your activity from hiberfil.sys, allowing you to resume your tasks instead of opening applications and documents from scratch.

Hibernation saves you time, but if you're not using it, turn it off to remove files that are taking up gigabytes of your disk space. You can then use that space to store other apps and files.

Disabling hibernation also helps fix problems with some drivers not working properly in this mode.
