Windows 11 Disable Hibernation File Jun 2026

Hibernation is a power-saving state designed primarily for laptops. It saves the contents of your RAM to your hard drive ( hiberfil.sys ) so you can resume work quickly without fully shutting down. However, if you are on a desktop PC, rarely use hibernation, or are trying to reclaim valuable SSD storage space, disabling hibernation is an effective way to free up gigabytes of data.

Windows 11, like its predecessors, uses a hibernation file (also known as a hiberfil.sys file) to store the current state of your system when you put it into hibernation mode. This file can take up a significant amount of space on your hard drive. If you don't use hibernation mode and want to free up disk space, you can safely disable the hibernation file.
