When your computer executes a task, it stores the data it’s working with in one of two locations: the RAM or the hard drive. If your computer runs out of the physical memory it needs to perform an operation, it moves data to a paging file on your disk. This paging file acts as virtual memory the PC can use as supplementary, or backup, memory. Windows 8 automatically sets the paging file to three times the amount of physical memory on your computer, but if you’re a heavy multi-tasker, you may need to increase your virtual memory for the best performance.
