The operating system transparently uses paging file to store data, and application is unable to control and perceive whether the data is stored in physical memory or in virtual memory, that is, the operating system decides to use physical memory, or paging file to store cached data. In general, monitor the use of memory resources at the Windows level by Performance Monitor. 1,
