I have a slight doubt regarding virtual memory.

Normally, it is up to the OS to provide virtual memory to using disk space to expand the amount of memory which appears to be available for applications.

The OS will clear physical memory by copying the data to disk and restoring when needed.

However, it is possible for an application to manage its own “virtual memory” rather than the OS, for example by writing objects to a file then destroying them?

If so, is allowing application to manage its own virtual memory for advantageous or allowing the OS to provide?

    Most applications would not be able to even know that they are being managed using virtual memory because the operating system would perform address translation on every memory request made by your application.

    This is a task definitely best left to the operating system unless you are working in a very low-level environment (in which case you are probably writing your own operating system anyway).

    Aside from the fact that this requires kernel privileges to accomplish, you would need to take care not to corrupt other process’ memory.

    The operating system is the best place for this kind of logic.
