The swap file is a file on the hard drive that is used when there is
insufficient memory (ram) to do the operations being run on the PC. This is
called paging which is a technique used by virtual memory operating systems
to help ensure that the data you need is available as quickly as possible.
The operating system copies a certain number of pages from your storage
device to main memory. When a program needs a page that is not in main
memory, the operating system copies the required page into memory and copies
another page back to the disk.
