I'm on XP professional, and i had set my page file up near the outer edge of the drive, and manually set it's minimum and maximum size to the same value(1gb), and unchecked the "system managed size" box. I did this so that it would be on the faster part of the disk, and also to stop it changing size and possibly fragmenting(it's quite a small partition). I've had no "windows is running low on virtual memory" messages..... but (and this has happened before) windows has took it upon itself to move my pagefile to the inside of the disk!!! the page file is now on the opposite side of the drive to all my programs and windows folders! which can't be good for performance. Why does it do this? And how can stop it doing it?

cheers

The block density at the center of the drive is much greater then it is at the edge of the drive. You should always let Windows Manage your paging file regardless of what people think. It shouldn't be changing it size as it is set statically to the amount of RAM you have. I have 4gigs of RAM and thusly my page file is 4 gigs. I do not see any performance hits with paging. If you are that concerned over paging, and you page a lot maybe its time to invest in more memory, or decrease the amount of applications you have open.

Can you post your system specs?

Thanks for the reply cryptodan,

i didn't want windows to move my pagefile, but it did! to a silly place!

it's just an old computer 1.1ghz, 700mb(ish)ram, 1gig pagefile,10gb partition. When ever i install windows xp, windows always places the page file (initially) in approximately the same place, towards the outer edge of the drive. Indeed, this it where it placed the page file on this install approximately 3 weeks ago. It had been happily sitting there until yesterday! when suddenly, for no apparent reason, it moved it! towards the inside of the drive. As stated above, i had opted not to let windows manage my pagefile, the main reason for this is because on such a small partition it's quite easy to get the pagefile fragmented, which does affect performance.

What i want to know, is .

1. why it does this.

2. how can i stop it!

Surely there must be a registry entry dictating this behaviour that you can turn off.

You have 10 GB hard disk and 700MB RAM. You should keep PageFile only 1050 MB. As cryptodan has suggested, your computer's hardware is limited so you should either stop opening many applications at once, cut down on always running apps. Or install bigger and faster hard disk and RAM.

As far as fragmentation of Pagefile is concerned, you can always defragment PageFile using PageDefrag. You can even set PageDefrag to run automatically at each boot.

thanks for the reply Romeo29

i know i can use page defrag, but i've set my computer up so that i shouldn't have to. You seem to be missing the point of my topic, Windows moved my pagefile (when i specifically told it not to) to another part of the partition. I want to stop it doing this. It's a wierd one, a google search has turned up nothing.

Your computer is very low specced for Windows XP Home or Professional. You need to stop messing with it, and let windows manage itself.

From everything I am able to find to answer your question about the location of your page file, "unchecked the "system managed size" box." does not have any effect on location on the disk. Even the term of the box you checked states "managed size". I can not find anything that would indicate utilizing that checkbox affects the location of the page file, and whether it will be moved by the OS, only the size of the page file and whether it's user or OS managed.

hi animal,

yes, checking the "custom size" box, and making the minimum and maximum size the same does not have anything to do with the location of the pagefile on the disk. It does however, keep the pagefile at a static size. And you would think that because it is a static size, it would just stay where ever it was. This doesn't seem to be the case. I was thinking that possibly there's a registry entry that dictates this behaviour,.

I have no answer to your question, just a question of my own since you have piqued my curiosity.

How do you know where on your disk your pagefile is?

Btw, I would not your call your computer crappy or let people who say you need more ram make you feel like it is or that you need more ram, especially if you do not have issues with speed. It is better than mine and I have no complaints about mine, not speed or anything else, although for all I know my pagefile keeps moving, lol. I have a slower processor and less ram, even so, I can still have multiple applications running and do whatever I want to with it and do not feel any need for more ram. The only thing I have that might be a bit better is a bigger hard drive but I still think between the two of us, you have the better computer. My processor is a P3 600 mhz, I only have 640 megs of ram and my harddrive holds about 37 gigs. Even with less ram and a slower processor, I do not consider my computer to be crappy at all and I have no complaints at all about the speed of it.

thanks Stang777,

this picture may help, on windows defrag you should see two green bands called "unmovable files" one is the pagefile and one is the reserve for the MFT. Athough on my picture the second smaller band is a pagefile fragment as i have no MFT reserve (this is because the disk got filled up and this space got used). I'm not sure how you tell which is which on windows defrag, your harddrive is 37gb i'm presuming your pagefile is around a gigabyte or just under, so the smaller band would probably be your pagefile. There is a freeware edition of ultimate defrag if you really wanted to find out, not sure how good it is but it's here

You are very welcome and thank you very much. I appreciate you taking the time to explain that to me and for the link to the free program. Thanks again.

O yea, you are pretty much correct about the size of my pagefile. I have it set to custom size and it shows it is currently set at 960 meg. It is set for a minimum of 960 and a maximum of 1920. That is how the techs who built the computer set it up and I have never messed with it as it works just fine with that setting.

I just downloaded that program and when I ever get around to defragging this thing, I will give it a try. I have actually never defragged it, the few times I have gone to do it, Windows has said it did not need to be defragged so I haven't done it. I don't know why, and I know it is stupid to feel this way, but I am a little nervous about doing it so when Windows says it isn't needed, I don't do it.

I hope you get your problem figured out and get your comptuer to do what you want it to do, good luck.

defragmenting is basicaly good house keeping, you can see on that picture i posted that my drive could do with a good defragmenting (the red areas are fragmented files) . It's always worth a check after you've install something new to see if it needs to be defragged, fragmenting becomes more of a problem and more common as your drive gets full up. Windows itself performs a partial defrag every three days in the background.

I think It's always worth making your own judgement when windows says that the volume doesn't need defragging, usually it's right, but i've had times where one file is fragmented and windows says there's no need to defrag, but the file is a film and because it's fragmented, playback isn't smooth.


And a note on that freeware program, if you try it it will ask you if you want to set it as your default defragger, you should probably tick no.

and thanks for the luck

Hi 666philb.

If you haven't seen it, there is a nice explanation about the page file on this page: http://aumha.org/win5/a/xpvm.htm

What may help explain your problem is in the section titled "Should the file be left on Drive C:?" about half way down the page. Check the last two(2) sentences in the paragraph of that section.
