Alternatively referred to as a page file or paging file, a swap file is a file on a hard drive that is used as a temporary location to store information not being used by the computer RAM. By using a swap file a computer can use more memory than what is physically installed in the computer. However, users who are low on hard drive space may notice that the computer runs slower because of the inability of the swap file to grow.
It is perfectly normal for the swap file or page file to grow, sometimes growing several hundred megs in size. Below is a listing of common Microsoft operating system swap file information; however, it is important to realize that this information may vary. Finally, by default the swap files are hidden.
|Operating system||Swap file name||Location|
|Windows NT, 2000, XP, Vista, and 7||PAGEFILE.SYS||C:\|
|Windows 95, 98, and ME||WIN386.SWP||C:\|
