The most widely used type of PostScript font.  In Windows, each font is composed of a .PFB and .PFM file, which are stored in the \PSFONTS and \PSFONTS\PFM folders.  Sometimes, \PSFONTS is in the \WINDOWS folder (\WINDOWS\PSFONTS).  Beginning with Windows 95/98, Adobe Type Manager lets you view the file names under the Properties of each font.  For example, the following files make up the Garamond typeface.  See
