If you want to create virtual memory on a secondary SSD or Page file on secondary drive to save space on primary drive, here is how you can do it.

In the early days of Windows, the pagefile helped make up for shortages in physical memory. But should you be using a pagefile on a virtual machine?

The Windows 11 page file (pagefile.sys) acts as a form of virtual memory for the operating system, freeing up the physical RAM for higher priority applications, drivers, files, etc.

Virtual memory can expand your PC's capabilities, but it will also slow it down. Understanding the swap file will help you make the right decision.

By default, Hyper-V assigns a measly amount of RAM to virtual machines you create. For best performance in the virtual PC, adjust these numbers, and use dynamic memory for maximum flexibility.

The virtual memory swap is essentially a page file, a reserved portion of the device storage that can be used as virtual memory when the device runs out of system memory.
