**** About .BAK Files ****
          
         You may notice one or more files on your diskette which end
         in .BAK.
          
         These are backup files which are included on your diskette.
         A backup file is a duplicate of another file on your
         diskette.
          
         The backup file will save you the time and expense of calling
         our office in the unlikely event that you receive a disk
         error while copying or reading the Thin-Font diskette.
          
         If you do receive a disk read error, or if you accidentally
         erase or damage one of the Thin-Font files you can
         easily restore the erased or damaged program file as follows:
          
         Type one or both of the following commands:
          
                  COPY THINFONT.BAK THINFONT.COM
                        
              or, COPY SETFONTS.BAK SETFONTS.COM
