I've used option 4 and disabled it in power options since Windows 7 came out. Am I good to go or is Windows still compiling a too-large hybernate file?

With 4gig of ram its around 2.5gig of RAM, 8 gig 2x times that. Don't fret, you can shrink it by doing this command... powercfg -h -size %60, %50 would be the lowest you can go..

I sure hope that's not right. If 50% is as low as you can go, I'm losing 16GB of SSD space.

I want it turned off, so it takes up zero space. Hibernate is useless to me. I've disabled it in Power Options. My question is whether it is still compiling a hybernate file or if disabling it there is sufficient.

I would imagine, but am not 100% certain, that if you disable it (in power options), the allocated space goes away. On my system, I get "all" of my space back according to the math above.

That command, I believe, adjusts it if its actually there.

Hokie... try that command and see what happens. Thats one way to find out!

Sorry to say, but it is... And you can't move the hibernation file either... Which stinks... powercfg -h -size 50, is the lowest you can go... With 4 gig of ram, it will go down to 1.7gig. So with 16gig of Ram, the lowest you can go would be about 7gig of RAM, 14 with 32gig of RAM... That's hibernation file we are talking about..

According to the link Thobel posted, that is incorrect.

This step will disable hibernation, delete the hiberfil.sys file, and remove the Allow hybrid sleep and Hibernate after Power Options under Sleep.

Correct... if you do powercfg hibernate off, the file disappears.

Do this...open up explorer show all system files (if not done already). open the root of drive C: and leave it open, then open up the cmd prompt, so now you have both windows open side by side.. now run that command, and watch the file appear, and disappear by changing it from on to off...

No.. I wasnt saying that..sorry I wasnt clear. I disable it like Hokie, in the Power Options.

EDIT: Post 66.

[hokiealumnus]

Ok, well that answers that! Hah...quite amusing. Turning hybernate off via power options does NOT remove the hybernate data file. Running the command "powercfg -h off" from an administrator command prompt took my free space from 57.4GB to 81.4GB. Yay.

EDIT - It was an instant change too. Looked at free space via my computer before running the command. Left that window open. Ran commend. Right-clicked in My Computer and selected "Refresh" and 24GB more space magically appeared.

You can do all that in the cmd prompt as well... I just like doing it that way, because its much easier to change than to find it in the GUI. I like to shut it off most of the time, and turn it on when I need it.. I made a simple batch file to do this..

Awesome... Glad I could help! Have you tried to shrink it, just to see if that could be an option for you?

[hokiealumnus]

Meh, not interested. If 50% is the minimum, with 32GB of RAM I'm looking at 16GB of wasted space on nothing I'd ever use. My machines are either ON or OFF.

EDIT - If I didn't use an SSD, Hibernate would probably make more sense. As it is, booting up from zero is so fast hibernate doesn't do anything for me other than take up space.

Thats incredibly weird... I must have disabled/turned something off along with the hibernation file to get my space back...

Now Im anxious to get home and try it.

Virtual memory and the page file are two different things. You can run out of virtual memory without ever having paged anything out of RAM. There is a connection between them though, in that the page file size in part determines the amount of virtual memory Windows will commit to. Even if you never page any memory page out to the page file, and even if you never use any program that makes use of the page file, it STILL is a bad idea to disable the page file because of its connection to virtual memory.

The best way to setup the page file on an SSD is to set a small initial size, say 512MB, and a larger maximum size, say size of your RAM plus a little more. This way you will only loose the initial size of 512MB unless Windows needs more. If it needs more it will grow the page file as needed, and then shrink it back down when it is no longer needed. The page file getting fragmented doesn't matter since it is on a SSD.

go to CMD promt

Tool it also provided links for a reg file to do it quick as in 2 on desktop on/off. Not everyone gets thrills from typing

[deathman20]

I've always used the command prompt commands to kill it. The file goes byebye then right after

Hyberfile is only good IMO for a lower processing computer with 2Gig of ram at most. Laptops mostly. Even then I have not had a system in recent times where Hybernation actually is quicker then a full shutdown/startup, only time was when I was working with a very large assembly in CAD and took nearly 2 hours to open it.
