Disable Hiberfil Sys Link -

This is the most direct method and works across all modern versions of Windows (7, 8, 10, and 11).

Document version: 1.0 Applicable to: Windows 10, Windows 11, Windows Server 2016+

After executing the disable command, perform the following checks to verify success:

As it turned out, hiberfil.sys was a system file created by Windows to store the contents of his computer's RAM when it went into hibernation mode. When John put his computer to sleep, Windows would save the current state of his system to this file, allowing it to resume where it left off when he woke it up. disable hiberfil sys

powercfg -h off

From then on, John was more mindful of his computer's power settings and made sure to shut it down properly when not in use. He was glad to have solved the mystery of the shrinking hard drive, and he was happy to have learned something new about how his computer worked.

. This allows your PC to shut down completely while still letting you pick up exactly where you left off. However, if you always use "Sleep" or just shut your computer down normally, this file is essentially dead weight—sitting there and hogging space on your SSD. Method 1: The Quickest Way (Command Prompt) This is the most reliable method. It tells Windows to turn off the hibernation feature entirely, which automatically deletes the This is the most direct method and works

If you've noticed a massive hidden file named hogging several gigabytes on your C: drive, you’re not alone. This file is the backbone of Windows' hibernation feature, and while it's useful for some, it can be a significant drain on storage for others. What is hiberfil.sys?

This recreates the file with the default size (approx. 40–75% of RAM). To set a (e.g., for Fast Startup only):

The problem was, John's computer was never really going into hibernation mode. He would occasionally put it to sleep, but it would always just wake up immediately. And yet, the hiberfil.sys file remained, taking up a substantial amount of space on his hard drive. powercfg -h off From then on, John was

powercfg -h on

If you need Fast Startup but want to reduce space, you can set a smaller hibernation file:

This is the most common reason. If you have a smaller SSD (e.g., 128GB or 256GB), freeing up 10GB+ can make a massive difference.

This command disabled hibernation mode and, more importantly, deleted the hiberfil.sys file. Suddenly, John's hard drive grew by several gigabytes, and he was relieved to have regained that much-needed space.
