When we click on the shutdown button in Windows, the system also offers us the possibility of , even in some cases, we can see how it also shows the option of Hibernate. A mode designed by Microsoft for the operating system to enter a special state to reduce power consumption and improve computer life. When entering hibernation mode, all files that are being executed are stored and information about the state of RAM memory before entering hibernation mode is saved. All this is stored in the hiberfil.sys filethat some of you may have seen on your hard drive.
What is the Windows hiberfil.sys file
Therefore, the hiberfil.sys file is directly related to the Windows hibernation process, since it is where the system stores all the current session information. Surely, many users will have thought on more than one occasion when they are about to delete everything they don’t use to recover disk space.
However, the hiberfil.sys file is essential for the correct operation of this function and is part of one of the main Windows utilities, therefore, it is necessary to be especially careful if we want to delete this file from the system. The first thing we should know is that deleting the hiberfil.sys file will prevent us from using the computer’s hibernation option again and we could even encounter problems when using any of the energy saving options.
If we want to activate or deactivate the Hibernate option in Windows 10, what we have to do is go to Settings > System > Startup/shutdown and sleepclick on the option Additional power settingswhich will open a Control Panel window, and then click on the option Choose behavior of the start / stop buttons that we find in the menu on the left side.
This will show us a new window in which within the section Shutdown Settingsor, we will find the box Hibernatewhich is the one that we must mark or unmark to activate or deactivate the function respectively.
How to delete the hiberfil.sys file
But if what we want is to delete the hiberfil.sys file to deactivate it completely and also recover important space on the hard disk, then we will have to open a window of the command prompt with administrator permissions. Once this is done, we write in the command line powercfg -h off and press Enter. Although no message is shown that the command has been executed correctly, we can go to the file explorer and check how the hiberfil.sys file has been deleted and the space it occupied has been released and available on our hard drive.
