I run windows 10 with 8GB of ram and 128GB SSD. I am constantly bombarded with warnings about being low on memory and Windows wants me to close some application. I looked into this and found out more about the pagefile system. I let Windows handle all memory allocation so now it grabs 20GB of my HD space and still throws errors about not having enough memory. - Windows

Are you getting notifications recurrently saying that your PC's memory is low and that Windows needs you to close an application? Or is your C drive running out of space because of a file called pagefile.sys? The memory problem may require you to restart your computer at least once daily, but it always reappears.

So, what is the cause of Windows' significant memory allocation and pagefile.sys huge issues, and what is the solution? Continue reading the article from EaseUS to deal with the problem.

What Is Pagefile.sys & Why Is It So Huge

Pagefile is a virtual memory file found on the C: drive by default. This file is not visible until you enable hidden file viewing on the system. So, to keep things running smoothly, your system will transfer some RAM to pagefile.sys when its RAM (random access memory) is low.

All the data you use, including open files and running programs, is stored in RAM. The computer keeps this data in RAM because reading from RAM loads much faster than reading from the hard drive. The RAM volume is limited. When RAM is almost full, the system will move any data that is either rarely used or not used to the pagefile.sys.

For example, when you minimize some web pages in Chrome, they do nothing but still use a lot of memory. Windows will transfer these rarely used memory pages to Pagefile to make more RAM available for the apps you currently use. That is why the size of pagefile.sys is huge.

Now you have learned what Pagefile is and why it's so large, don't forget to share the information with other users who may find it useful and then dive into the solutions below.


3 Solutions to Pagefile.sys Huge Issue

We have curated three solutions for you to solve the pagefile.sys huge issue as given below:

  1. Way 1. Move Pagefile.sys to Another Drive
  2. Way 2. Expand C Drive
  3. Way 3. Reduce Pagefile.sys Size

Way 1. Move Pagefile.sys to Another Drive

In this method, we will show you how to move pagefile.sys to another drive in Windows via the Settings app to improve your PC's performance:

Step 1. Open Settings and navigate to "System" > "About"

Step 2. Click "Advanced system settings" next to Related links.


Step 3. In the System Properties pop-up window, click the "Advanced" tab. Next, under the Performance section, click the "Settings" button.


Step 4. In the Performance Options pop-up window, click the "Advanced" tab. Next, under the Virtual memory section, click the "Change" button.


Step 5. Uncheck "Automatically manage paging file size for all drives" in the Virtual Memory window.

Step 6. Under the Paging file size for each drive section, choose the C drive and select the "No paging file" option.


Disable the paging file on the primary drive if you want to store the virtual memory file on a different drive. It is often advised to leave the paging file enabled on the main drive to enable the system to produce crash dumps in case of a system error. While Windows will use the second drive's paging files more frequently to store unused pages until they are no longer needed temporarily, you can still set virtual memory on the new drive if the paging file is left on the main drive. This will improve system performance significantly.

Step 7. Click the "Set" button. Click "Yes" when prompted.

Step 8. Select the drive you want to save the pagefile, for example, D:. Next, select the "System managed size" option. Click the "Set" button.


You cannot set a pagefile if your BitLocker volume is locked. You will need to unlock the volume and try again. If it is already unlocked, continue to the following steps.


Step 9. Click "OK" and then "Apply."

Step 10. Click "OK" and restart your PC.

After you complete the steps, Windows will automatically create a new pagefile.sys file in the new location that contains the virtual memory content to enhance your PC's performance.
