What is system hibernation hiberfil.sys

Computer hibernation is to write the information in the memory to the hard disk, and generate a file of about the same size as the memory as a record in the system disk. When restarting, just read the information into the memory. The speed is faster than restarting. When using hibernation mode, you can turn off the computer and be sure that all your work (including programs and documents that have not been saved or closed in time) will be completely and accurately restored to the state when you left when you come back. The contents of the memory will be saved on the disk, the monitor and hard disk will be turned off, and at the same time, power will be saved and the loss of the computer will be reduced. Generally speaking, it takes longer to remove the computer from hibernation than to remove the standby state, but the hibernation state consumes less power.

The Hiberfil.sys hidden system file is located in the root folder of the drive where the operating system is installed. The Windows Kernel Power Manager reserves this file when you install Windows. The size of this file is approximately equal to the random access memory (RAM) installed on the computer.

When the hybrid sleep setting is turned on, the computer uses the Hiberfil.sys file to store a copy of the system memory on the hard disk. If this file does not exist, the computer cannot hibernate.

Disable system hibernation and delete the Hiberfil.sys hidden file

Hiberfil.sys is a hidden system file that is very large and hidden in the root directory of the system disk (unless you modify the path through regedit). This is different from the pagefile.sys file (used for virtual memory). The pagefile.sys file can be freely changed in the computer's system settings to determine which disk it is transferred to. To find the hiberfil.sys file, uncheck "Hide protected system files" in the folder options.

We use the command line tool to completely turn off the Windows hibernation function and hope to completely delete this large file. First, open the Run in the system start menu (you can press the shortcut key Windows+R), then enter cmd and press Enter to confirm.

Note: You need to run the command prompt cmd window as an administrator.

After entering the command line interface, enter in the command window powercfg -h off, you can turn off the hibernation function, and the Hiberfil.sys file will be automatically deleted.
