Pagefile is a hidden system file stored in the system drive of the computer. It is stored with the extension .SYS. This system file is responsible for the smooth working of the computer by reducing the workload of the RAM.
Pagefile.sys acts as a secondary RAM and it is designed for accommodating the already present programs in the RAM so that the new applications which you want to download has space. This is why Pagefile.sys is often referred to as Virtual Memory.
