hiberfil.sys

About this tag
The hiberfil.sys file is a system file used by Windows to store the contents of RAM when the computer enters hibernation. Users on WindowsForum.com discuss managing this file to free up disk space, especially on devices with limited storage like tablets or SSDs. Common questions include whether it is safe to delete hiberfil.sys, how to disable hibernation to remove it, and why the file may reappear after reboot. Some users report that Windows updates can increase the file size unexpectedly. The file can be managed via the powercfg command, but caution is advised as it is tied to system features like fast startup.
