What is Pagefile.sys? Can i delete it? Hello everybody.

Leo Notenboom here for Askleo.com. This is one of the most common questions many people ask themselves when they stumble upon Pagefile.sys.

And you can see how big it is, Pagefile.sys for short. This is a file that Windows creates and uses to hold what is known as virtual memory.

Virtual memory is essentially the operating system that uses disk space instead of actual memory, instead of actual memory when the system is running out of memory. Say you have eight gigabytes of RAM on your system, but the software you're running kind of wants to use 10 total. So you want to use more RAM than you actually have installed in your system.

What Windows is going to do is check how the RAM is currently being used, and it will take the stuff that hasn't been used in a while, whatever that may be, and actually apply it to the that way Write to hard disk. This memory, the actual physical RAM, can be freed and used by anyone else who needs the RAM at this point in time. The hard drive that wrote it to is this file called Pagefile.sys.

Paging is the process of actually writing blocks or pages of memory to disk and when they are needed. Read them back in later. So it can get pretty complicated, it can get pretty disk intensive when you're actually using a lot more RAM than you have physically installed in your computer.

So can you get rid of it? First we go to the computer and look at Pagefile.sys. So this is my Windows 10 home computer, I'm just going to start Windows Explorer here and go to the root directory of my C drive, see there's nothing here.

That means I have to change some options or go to Options, change folder and search options on the View tab. There are a number of options that I often enjoy playing with. The one we're interested in here is this Show Hidden Files, Folders, and Drives show.

We'll also be clicking on hideextensions because that's a security issue that I really, really don't like. And then we'll get the option to hide protected ones too Disable operating system files. While there is a warning, this is exactly what we want.

I'll strike, OK? And now you can see that there are a lot more files here in the root directory of C than we originally thought. In fact, one of those files is Pagefile.sys.

You can see here that it is a gigabyte and a half of hard drive space. It's more or less proportional to the amount of memory you have in your system. The exact default settings will vary based on a number of different things, but it's something you can control now.

Of course, we'd like to see one of the things right away, whether we can just delete it. But of course we can't. The file is open in another program Pagefile.sys is always opened by Windows if the system is configured to use virtual memory at all.

So that means you can't delete it, at least not the way we just set it up. To change the paging file, we go to the system properties, to the system element and then scroll down in the system to the advanced system settings. In the advanced system settings you will see the 'Advanced' tab and you will see that there is a performance element here that includes virtual memory.

We click on Settings. We click on Advanced again at the bottom of the virtual memory. It tells us.

Yes, we have a one point four gigabyte paging file. Let's change that. Now, this is the default with Windows actually managing the paging file for you.

This is a good default unless you want to do something else for some reason. And as you can see here, we have the option of moving the paging file to potentially different drives. We have the option to completely disable them.

And I'll do that now. Well, turn off the auto-managed paging file size for all drives so that the system paging file, location and size is now completely under our control for drive C. It says Manage System.

I don't say a swap file and press set. Now, of course, you will find that it warns us that this can lead to problems line, the problem is that without a paging file you have the possibility of running out of memory sooner than if you had a paging file. If you've enabled a paging file and let Windows control its size, Windows can essentially allocate as much memory as your programs need, regardless of how much RAM you have installed in your system.

There's a performance hit because you're obviously relying on that Hit hard drive instead of just using RAM, which is faster. But if you know you will never ask for more RAM than is actually installed in your system, this is it for you, so I want to continue? Yes I do. And now you can see the paging file size here none, none, none and none, in other words when i finish there will be no paging i click ok and you can see yes it needs a reboot for this change to take effect.

I'll do that. And we're back. Log into Windows.

Of course it will still boot during the startup process, so it will be a little slower, but nonetheless we can go ahead and start Windows File Explorer right away, back to the root directory of our C drive to make it a little bigger this time. And you will see that the paging file was gone if you could have deleted it yourself at this point. But Windows is nice and it cleans up on its own and actually removes the paging file for you.

The other approach, of course, is to use a different operating system to boot from a live Linux CD or DVD, for example, so that you can actually access the contents of the hard drive. While Windows won't run itself in such a situation, the file won't be locked because Windows isn't running and you can actually delete the file. Here is the problem.

If you do not change the Windows configuration to no longer need or use a paging file or paging file, it will be automatically recreated the next time Windows boots. The only way to get rid of the paging file is to stop using the virtual memory in Wind to disable ows. I don't recommend that, you can do it knowing you will always have plenty of RAM available for whatever applications you run, but in general we don't.

Generally there there are always situations where we suddenly forgot that we have too many browser tabs open and Windows starts to manage the virtual memory for us so it doesn't crash. I hope that was helpful. I hope this was some information for updates.
