pagefile.sys / hiberfil.sys

Hi chaps.

Just noticed I have the two above files have decided to add themselves to my OS drive. Now I would have not noticed this usually, bar the fact my new OS drive is a 30gb Kingston SSD.

They are over 7.5gb in total which now only leaves me 3gb for any future drivers.

If someone can tell me why they have appeared and how I can get rid I would be most grateful.

My new setup has been fine for 6 weeks without this appearing.

I understand they could have appeared as I may have a memory problem elsewhere?

The only thing I have fiddled with over the weekend is an OC on my CPU. Could this have caused this?

Thanks in advance for any responses.

hiberfil.sys is used by hibernation. you can disable this running a command prompt as administrator and then entering this command...

powercfg -h off

you need pagefile.sys for the system pagefile - but if there's not enough room on your disk, you can change it's location. right click "computer", properties, advanced system settings, advanced tab, performance> settings, advanced tab (again

), virtual memory>change. untick automatically manage and play around there. make sure it's set to system managed on at least one drive. don't try and be a smart arse by disabling it altogether. it won't work.

They would have always been there n00b, why not ask the person who built it.

pagefile.sys is your swap file, don't recommend turning it off but you could resize it or move it.

The other one is there encase you want to hibernate the PC instead of shutting down, you can get rid of it by opening a CMD window and doing...

powercfg -H OFF

might need a reboot and then you can delete the file.

edit:dang, beaten

No it was not mate I had 10gb free until yesterday

It just appeared yesterday, or it was a lot smaller!

Right got rid of that hibernating file so cheers for that.

Chaos, you can sort out the other thing on TeamViewer later.

The pagefile by default will resize itself as necessary. At some point recently it may have needed to expand it by a fair chunk - enough for you to spot it!

Normally I would say leave it on the SSD as you will get better performance [whether or not its noticeable on any particular system is another matter!]. However, since your SSD is tiny I would move it to a different drive.
