A couple of final limits related to virtual memory are the maximum size and number of paging files supported by Windows. 32-bit Windows has a maximum paging file size of 16TB (4GB if you for some reason run in non-PAE mode) and 64-bit Windows can having paging files that are up to 16TB in size on x64 and 32TB on IA64.
In computing, virtual memory is a memory management technique that provides an idealized abstraction of the storage resources that are actually available on a given machine which creates the illusion to users of a very large memory. The computer's operating system, using a combination of hardware and software, maps memory addresses used by a program, called virtual addresses, into physical addresses in computer memory. Main storage, as seen by a process or task, appears as a contiguous addre
