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?

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:
