How to Delete hiberfil.sys to Free Storage in Windows

Once you use a device for a long period, you are bound to run out of storage. While there are multiple ways of fixing low storage issues, did you know that there are system reserve memory files that can be deleted to free storage space, such as hiberfil.sys?

How to Delete hiberfil.sys to Free Storage in Windows

Hiberfil.sys is a system file that can be safely deleted to free up space. In this article, you will understand the purpose of this file and how to delete it for more space.

What Is the hiberfil.sys File

If you ever stumbled across the power modes on Windows, you must have come across the Hibernate mode. It is a power saver feature that saves the current session to the hard disk before shutting down the PC. Once you boot it up, you can continue your session without having to re-open applications and programs.

Now, your computer needs to have an assigned space to store all these session-related data. This is why we have the hiberfil.sys files. Moreover, these program data have to be moved from the RAM to the hard disk, where they are stored.

The file size is close to the size of the RAM and is usually around 50-75% of the RAM size. This means that it occupies multiple gigabytes of storage. If you are curious to know how much size it occupies, move on to the next section.

Both deleting and restoring are safe procedures.

Should You Disable Hibernation

The main difference between Sleep mode and Hibernate mode is that hibernation uses less power. If this feature is useful, we recommend against deleting hiberfil.sys. If this feature isn’t necessary and freeing storage space is important, delete those files. Additionally, if you have administrator privileges, you can access Command Prompt to delete those files.
