Look at the list of drives in the field at the top of the window. If there is a paging file size indicated for a drive (there may be more than one), then there is a pagefile.sys file located in the root directory of that drive. For example, if there is a paging file size indicated for drive C:, then the location for the paging file on that drive is C:\pagefile.sys. If there is no paging file size indicated for any drive, that means that pagefile.sys does not exist on your computer
