Instructions for changing Pagefile.sys size and location on Windows

Although Pagefile.sys takes up a lot of space in your drive, the computer uses it to maintain the storage of important data in the computer instead of deleting these data when RAM is overloaded.

To free up space and drive space, you can change Pagefile.sys size and location on your computer.

1. What is Pagefile.sys?

Windows uses a file called Pagefile.sys as a virtual memory because the RAM in the machine can only record a certain amount.

Pagefile.sys is located in the hard drive or SSD (C: pagefile.sys) to support the limited write ability of RAM in the computer when needed.

Your computer will prioritize the use of RAM to store data because its accessibility is faster than hard drive. However, when RAM is full or overloaded, Windows will automatically transfer data from RAM to Pagefile.sys in the hard drive.
