Pagefile.sys a 'file' generated/used by W2K (NT) as 'virtual' memory; that part of the drive behaves as though it was RAM... When physical RAM is fully used and there is need for more, infomation/data not currently being accessed can be 'swaped' to that location and thus free physical RAM for immediate use. That same data can be transferred back if need be into physical RAM at any time. If the Page-file (Swap-file) is being overly accessed/used then one would normally add extra RAM; extra RAM is the simplest way (usually the cheapest too) to improve overall performance of a given system.
Pagefile.sys is the Windows paging file, also known as the file that Windows uses as Virtual Memory. As I've discussed before, Virtual Memory is simply disk space that Windows uses when it runs out of physical memory or RAM. Some of the contents of RAM are written out to disk to make room for whatever other memory request might have come in.
To avoid some of the drawbacks of Vista’s Sleep power-saving mode, you can hibernate your PC. Hibernate saves a copy of everything in your PC’s memory (RAM) onto your hard disk before it shuts down.
Windows uses the file hiberfil.sys, stored in the root folder of your hard disk, to hold your hibernation data. Because it must hold everything in memory, its size is the same as the amount of installed system memory.
