Because your Smode station is not necessarily on a laptop, you can display the usage of the very huge hiberfil.sys by typing a special command in the command prompt.
Fot this, click on the windows menu and type cmd in the search bar. Then right click on the Command Prompt to run it as an Administrator.
Accept the User Account Control to make changes.
Then type "powercfg -h off" this will delete the hiberfil.sys file.
To avoid OS prompt to launch system restoration at boot when an unexpected reboot crash happen (useful when computer are only remotely accessible without physical keyboard, also type the following command: "bcdedit /set {current} bootstatuspolicy ingoreallfailures" ).
You can now close the console.
