In Windows 10, the hibernate mode is enabled by default. The Hibernate mode is the power saving mode for computers that run on batteries like the laptops. This mode is not a requirement for desktop users, as they run on power supplies and UPS. Hibernation puts the full current state of your PC to the hiberfile (C:\hiberfil.sys) and then turns off your computer. Hibernate mode is slower as compared to sleep but consumes less power than Sleep Mode. The size of the hiberfil.sys is usually 75% of your RAM. If your computer’s RAM size is not so large, and you want to reduce the size, then you have to run a simple command in the elevated command prompt. Remember that the minimum size of the hiberfil.sys has to be 50%. Check out the article below.
Steps to reduce hibernate hiberfil.sys file size in Windows 10
1. Press Win+X OR right click on the Start Button. Now go to Command Prompt (Admin) to open the Elevated Command Prompt.
2. If you want to reduce Hiberfile.sys size to 50%, then type the following command and hit Enter.
powercfg -h -size 50
Note: the number 50 can be replaced by any number depending on your requirement. But you cannot make it less than 50. 50 is the minimum value you can set!
