Explanation
Virtual memory (implemented as the pagefile, pagefile.sys, in Windows) acts as an overflow extension of physical RAM.

The pagefile therefore stores the memory pages of running processes. Documents, application data files, and file metadata are stored on disk in the regular file system, not in virtual memory.
