Windows 10: Page and Swap File?

I've set the Page File for my C: drive to No Page File and my D: to System Managed.
Doing this places the Page File on my D: drive,
which is the faster of the 2 drives.




The question is,
should I still have a Swap File on my C: drive and also one on my D: drive?

Here's a screenshot of the C: drive.
Notice the Swap File and no Page File.




Here's a screenshot of the D: drive.
Make note of the Page File and also the Swap File.




I was under the impression,
that if I disable the Page Files on a specific drive,
that both Page and Swap Files shouldn't be present on this drive?
Is it normal to have 2 Swap Files of the same size on different drives?

N95 New Firmware

demand paging make this like swap file i think

 

On Windows 10, how do I download stuff from the Windows App Store?

I finally got Windows Update to work but the the App Store still doesn't work. I can click to download Netflix, nothing happens except 'Working..." pops up, navigate back to the home screen, click on say Facebook and then click to download via the 'Free
button' again and the page swaps back to the Netflix page. Click the 'Free button' on the Netflix page now and it swaps me back to the Facebook page...

 

Hi, this may be of interest- apologies if all is familiar.
I've moved my pagefile.sys off my (C: ) - swapfile.sys is only present on C:

 

No this is not familiar.
I don't understand why I have two swap files.
Should I only have one swapfile.sys?
If so, how can I change this?

 

Sorry- missed the URL I meant to post:

I can only say what I observe on my PC, I'm afraid..

 

Okay, thanks for the link.
I understand what and why there are these kinds of files.
The question is...
If I set my C drive to No Page File and then set the page file to be on my D drive as System Managed.
Why is it that I have 2 swap files, and are both swap files being used, or not?

Also if you placed your page file on another drive, other then the C drive.
Why is it that you only have one swap file, yet I've done the same thing and I have 2 swap files?

 

Hi, this -er- curiously read video
How to Delete the Swapfile.sys File - windows 10 - YouTube
and this - see the section
Moving Swapfile.sys to another location/drive
http://www.download3k.com/articles/H....1-or-10-00430

in particular indicate the process of moving the files.

They don't necessarily move together.

I would assume from this that to successfully move BOTH files you have to be careful in the sequence.
It should follow that
- one of yours is redundant
- I could consider moving my swapfile.sys if I wished.

 

Thanks again for the links.
Didn't you say that you only have one swap file, so why would you want to move it?

I on the other hand have 2 such file.
Would it be safe, if I could, to just remove one of them?

 

I would assume you should be able to delete one- should be under 256Mb. Simply check the date modified.. one of yours will hopefully be old.

Otherwise I'm simply commenting on the differences.. and saying 'I could'..

 

I'm confused, so I just set the page file to be system managed for all drives.
Now I have 2 page file and 2 swap files, one swap and page file for each drive.

 

I've always seen paging file [virtual memory] on Windows NT-based versions and swap file on Windows ME and earlier.

I set the paging file on the C: drive at 2048MB and on a second hard drive at the recommended 1.5 times the physical RAM. With 8GB RAM that would be 2048MB on C: and 12288 on D:. I've seen marked improvement in system performance on the computers. Some program installations look for the paging file on the same drive as the OS.

 

I was mainly concerned about the 2 swap files, but now I don't really care any more.
I also have 8GB's, so I'll give your configuration a try, it couldn't hurt, or at least I hope it doesn't hurt.
Thanks.

 

Just to check- Win 8 & Win 10 have both a pagefile.sys and swapfile.sys - not to be confused with the older nomenclature (win 7 and earlier) where the pagefile was also referred to as the swap file for legacy reasons.

 

True.

The term "swapfile" is an old one, dating back to a time when the OS would swap entire processes to disk. This wasn't very efficient but the best that could be done with the relatively primitive hardware available. But in the NT platform (and Windows 95, 98, ME) data was written to disk in pages of 4096 bytes. As a reflection of this the former swapfile became pagefile.sys, although the older term remained in use in Windows 9x. It iterm s still used in Linux, even though it is actual used for pages of data.

That changed in Windows 8. pagefile.sys kept it's traditional role but a new swapfile.sys was introduced to page out the modern Apps. These are very small in comparison to traditional applications. For technical reasons it was more efficient to use a different file for this purpose. So in Windows 8 and later we have both pagefile.sys and swapfile.sys serving different purposes.

There is some value in having a pagefile (or swapfile) on a separate physical drive other than that containing the OS. This largely disappears when SSDs are being used. But note carefully that these must be separate physical drives, not partitions. In the latter case performance would be impaired.

But if you have a reasonable amount of RAM for your workload you won't gain much by doing this. This also assumes that the other drive is at least as fast as the OS drive.

I do wonder though why the OS isn't on the faster drive. That would make more difference than anything you could do with the pagefile.
