Today’s computers offer a range of energy-saving options. These features are especially useful for laptops, which often run on battery power instead of being plugged in. One of the most well-known features for saving power and battery is Hibernate mode (also called Suspend to disk), which powers off your computer. Before the operating system shuts down, it stores your current user session to the hard disk so that you can continue exactly where you left off when your computer wakes up from hibernation.
Microsoft systems such as Windows 7, 8, or 10 store this memory content to the hiberfil.sys file, which can use several GBs of space depending on the software, system version and type of device you’re using. Windows creates this system memory file even if you never use Hibernatemode or Sleep mode, which also uses the hibernation method. We’ll explain how to delete the hiberfil.sys file and prevent the automatic creation of a new hiberfil.sys file if you don’t use the hibernation feature in Windows.
