Windows 10 is a very resource-intensive operating system. Sometimes your physical memory is not enough to run all the processes at a time. In this type of situation, there are high chances of crashing the system.
But Microsoft teams have a fix for this through a special paging file called “pagefile.sys”. Pagefile.sys is basically a swap file that is designed to improve the Windows performance. It is a portion of the hard drive that acts as virtual memory.
As I said earlier when your windows physical memory (RAM) is insufficient to handle the process the pagefile.sys act as a virtual ram and power the windows to keep the running process without crashing the system.

What is Pagefile.sys?
Pagefile.sys is a swap file that is stored on the hard drive and acts as a virtual RAM for the windows to provide a smoother experience. This file is divided into serval parts to provide a better performance and is stored inside the C drive of PC.
|File Size||Approx 12GB. But depends upon the physical memory.|
|Description||A swap file that acts as a virtual RAM to improve the windows performance.|
|Is it a Virus?||No, it is a system file.|

If your windows physical memory doesn’t have enough capacity to hold another data, the files are paged on the pagefile.sys. It acts as a backup for physical memory. The RAM stores the data for a temporary period.
But the Pagefile.sys store the data until you delete it yourself. It also acts when your pc crashes suddenly or power interruption. If you have installed windows on an SSD drive then the paging speed will increase 10x faster then a physical memory.
This is why windows use the pagefile so that the users will never face any issue while operating with the system. This increases the overall performance of the pc along with a backup option to RAM.
