It is used to suspend/resume modern Windows apps. It was first introduced in Windows 8 along with pagefile.sys file.

In simple terms, when the system detects pressure in terms of memory then swapfile.sys comes into action. It mainly suspends apps which are not being used by user at that point of time to gain additional memory. It frees up space for the system which can be used for current app or any other important background activity. When the memory pressure on system is low then swapfile.sys will again resume the apps for the user.
