Hiberfil.sys file: what should you do with it?

• Sleep mode - this provides enough power to keep your computer's memory running.

• The hibernation mode is an even more efficient option for saving energy, as it writes information from memory to the hard disk and, in fact, shuts down. In this case, restoring the computer is much faster than taking it out of a complete shutdown state. Windows writes information from memory to a specific file, and this is the hiberfil.sys file.

Windows 10, 8, 7, Vista

When hibernation mode is disabled, the hiberfil.sys file is automatically deleted, which, in principle, is needed to increase disk space.

So, in order to turn off hibernation mode in Windows 10, 8, 7, Vista, you will need to use the command prompt in administrator mode. However, there is nothing difficult in this; only one simple command is needed.

Click "Start" and type "command prompt", right-click the desired result, and select "Run as administrator".

You are in a command prompt window. Here, enter the following command and press Enter: powercfg -h off.

After restarting your computer, you will notice that this Hibernation option is no longer in the shutdown menu. You can also go to explorer, and you will see that the hiberfil.sys file has been deleted. All freed up disk space is yours again.

If you suddenly want to turn on hibernation again, just go to the command line as described above and enter this command: powercfg -h on, press Enter.

Windows will then recreate the hiberfil.sys file, and activate the hibernation function.

If you are suddenly faced with the problem of damaged or deleted files that you really need, you can rest easy
