Hello,

the paging file is a reserved by the operating system, as sort of like a back up ram. When your system runs out of a ram to cache your programs, those programs need to be cached somewhere, so it writes, temporary data on your hard drive to be used by programs. Usually when your ram runs out of run your get dynamic slow downs.
