When Windows runs on low memory, it uses a small portion of the hard drive to function smoothly. To do it, Windows creates a file named pagefile.sys and stores less important memory bits into it. As a result, Windows can use it as virtual memory. Random access memory (RAM) and pagefile swap data between themselves continuously.
Pagefile is very important for your PC. It helps to make sure that you have free available RAM so that you can do tasks smoothly. But, If there was no pagefile.sys, it would not be possible.
