I have a 3.5GB hiberfil.sys file on my OS drive but am unsure why it is there. I understand it is used for system hibernation, I also understand I can disable it.

The thing is, on my machine I don't even seem to have the option to hibernate (Win 10 Ent). If hibernating isn't an option, why do I have this file on my drive taking up space? If hibernating is an option, how do you initiate it?

Shutdown menu#

    Your screenshot isn't clear. It makes no mention of hibernate. Have you attempted to enable hibernation then disable it? – Ramhound Mar 28 '16 at 22:02
  • Like I said in the question, I don't have an option to hibernate, that's why there is no mention of it in the screenshot. I also cannot find an option to en/disable hibernation anywhere. Have looked in Power Options in Control Panel but couldn't find anything. – Jonny Wright Mar 28 '16 at 22:04

  • @Moab I know it is. I am asking why the file is on my drive when hibernating the machine doesn't seem to be possible. – Jonny Wright Mar 28 '16 at 22:11

hiberfil.sys is not only used for hibernate, but also hybrid sleep and fast startup

And for the hibernate option on the power menu, go to Power Options and click Choose what the power buttons do on the left, and then:

  • To add from Windows 8 and above, hybrid booting meant that when you hit shutdown button it would actually hibernate along with some other things. – Racing121 Mar 28 '16 at 22:34
  • I see. So hibernate is effectively part of the normal shutdown procedure now? Now it makes sense why I have the file even without the option to hibernate. – Jonny Wright Mar 28 '16 at 23:51
