Manage Virtual Memory Paging File in Windows 11

A paging file (aka: “page file” and “virtual memory”) enables the system to remove infrequently accessed modified data from physical memory to let the system use physical memory more efficiently for more frequently accessed data.

Windows also uses the page file to store data when physical memory (RAM) is full.

The system automatically manages the size of the paging file (“C:\pagefile.sys”) on the Windows drive by default.

However, there may be times you may need to manually manage the paging file. For example:

  • If the C: drive that Windows is installed on is small in size, you may wish to remove the paging file from that drive, and add a paging file to another drive with more space instead.
  • If you use a lot of memory, then you may wish to add a paging file to another drive to have available if needed.
  • If you don’t use a lot of memory and your paging file is large in size, you may wish to use a smaller custom size.
  • If you are getting a BSOD PAGE_FAULT_IN_NONPAGED_AREA or KERNEL_DATA_INPAGE_ERROR or Low Memory type error when the paging file size is not system managed, you may need to set a larger custom size for the paging file.

This tutorial will show you how to manage the virtual memory paging file for each drive on your Windows 10 and Windows 11 PC.
