ARCHIVED: In Windows, what is a swap file?
A swap file, also called a page file, is an area on the hard drive used for temporary storage of information. Windows uses the swap file to improve performance. A computer normally uses primary memory, or RAM, to store information used for current operations, but the swap file serves as additional memory available to hold additional data.
Note: Microsoft recommends that you allow Windows to manage the Virtual Memory settings for you (i.e., leave the default setting as is). Only experienced users should change this setting, as it can adversely affect system performance.
Also note that you can manually move the location of the swap file to a different drive. In some situations, this can be advantageous. If you have a drive with more free space or a faster access time, you may improve performance by moving the swap file to this drive.
Windows 7, Vista, and XP allow you to set up swap files for each drive on your system. In these versions of the Windows operating system, the swap file is dynamic and hidden.

The name of the Windows XP swap file is
located in the root directory. The swap file is dynamic, changing
size depending on system conditions. If you run several applications
at once, the swap file will grow to accommodate the additional
information required to run each application smoothly. This is a
hidden file, so you will have to change your folder view setting to be
able to see the file.
