The hibernation file is called hiberfil.sys and it’s under the root
of the system drive. It’s the file that system writes the contents of
physical memory to when you put the computer
to hibernation. The size is uaually the size of your physical memory.
If you use the power options in Control Panel,
you can turn off hibernation. However, the hibernation file remains. To
disable hibernation and delete the hibernation file, you have to use
powercfg command line tool. Follow these steps.
- Open up an elevated command prompt (run command prompt as administrator)
- Type this command:
powercfg -h off
If you ever want to turn it back on. Just type
powercfg -h on
