What is the file Hiberfil.sys and how to disable or delete it in Windows 10, 7

The Windows operating system creates a file named hiberfil.sys when you enable the sleep (hibernation) feature. The hiberfil.sys file is saved in the root directory of the Windows installation disk. For example, if you installed windows on a local “C” drive, then the file is located there. The hiberfil.sys file is not visible with the default settings. You need to configure in Explorer to display protected system files, as well as hidden files and folders. Depending on the size of the RAM installed on your computer or laptop, the hiberfil.sys file may consume from several hundred MB to GB. As a rule, the size of the hiberfil.sys file in windows 10, windows 7 is approximately 30-70% of the amount of RAM on your computer, laptop.
