How To Reduce Hibernate File Size In Windows 7

Most of Windows users use hibernation feature to quickly boot into Windows and resume their work. Though, by default, it’s not enabled in Windows 7.

When you enable hibernate feature, Windows creates a new file named hiberfil.sys in the root of your system drive to save the system state.

Now, if you have a hiberfil.sys with a huge size, you might want to reduce its size to free-up some disk space. The default size of hiberfil.sys varies depending on the amount of RAM installed on your PC. For instance, it’s taking 2.97 GB of disk space on my PC with 4 GB of RAM.

One can reduce the hiberfil.sys file size by executing a simple command in the elevated Command Prompt. Here is how to do it:

1. Open elevated Command Prompt by typing CMD in Start menu search filed and then hitting enter. Alternatively, go to Start menu, All programs, Accessories, right-click on Command Prompt entry and then select Run as administrator option.

2. In the command prompt, type the following command and hit enter.

Powercfg –h –size percentsize

In the above command, replace percentsize with your value (for example, 60%), but it cannot be smaller than 50.

3. Exit the Command Prompt and you are done!
