By | December 27, 2016


Hiberfil.sys is a large file of our computer created by Windows. When our PC is in hibernate mode (write memory to hard disk), it uses this file hiberfil.sys to store all the memory data.

Important note: If you use hibernate mode don’t delete the file.


If you don’t use this mode because you use sleep mode or whatever reason then you should definitely clear this file to empty disk space. This guide should work on all Windows versions.
