Do you know what the adverse affects might be if I reduce the size of the pagefile.sys file?

Thanks again.

24GB. I am not worthy. I only have 4GB.

You can set it to zero but I have heard of stability problems if you do that. I would just leave it as it is.

Haha... sometimes it feels like having more memory just allows my machine to fail more powerfully, though.

Thanks once again for all your help.

If you don't use Hibernation you can delete the hiberfil. It would be re-created on shutdown if you do, and sized according to whatever you had running in your RAM at the time of shutdown. There's controversy galore regarding the pagefile.sys, but with your amount of memory, unless you are doing something very special wrt specific programs, you ought to be able to simply specify a smaller pagefile e.g. 1Gb.

Many thanks.

I'll get rid of the Hibernation file in that case.

I'll also try to reduce the size of the pagefile.

Thanks for your advice.

To get rid of the hiberfile, open an elevated command prompt and run this command:

powercfg -h off

Then hit Enter. That's all.

Is it better to use this method than just deleting it using SpaceSniffer?

Can the 'pagefile.sys' file be moved to another drive somehow? That file is huge.

I keep my C Drive solely for the system and applications. I have other drives for work and generated files. If that file could be moved somehow to another drive it would solve a lot of my problems.

Thanks again for everyones help and advice.

Seany you should have gained 40+Gb by eliminating the hiberfil and reducing the pagefile to just one Gig--why do you feel you need more?

I would reduce the size of the pagefile, but not move it to a spinner myself.

It is not only better, it is also easier. Takes 20 seconds.

And Maxseven is right. Your pagefile will be hardly ever used. But some programs need it for a short period. 1 or 2GBs should suffice. Eliminating it completel would get you BSODs.

You can resize the pagefile by
Computer > Properties > Advanced System Settings > Advanced (Tab).Performance.

It's supposedly better to set it to some fixed size (min size = max size). Try setting it to 1GB and see what happens (nothing terrible can happen - it might run slow); I've run with 100MB w/o problems (4GB mem, using Photoshop, etc); with 24GB of mem you might never use it at all. You can also put all or part of the the pagefile on another disk, such as your data disk(s).

You can get rid of the hiberfile by turning off hibernation, then reboot.
