8.3
     
         a common shorthand for the
        limits on filename length imposed by the file system used by
        ms-dos and microsoft windows - at most eight characters,
        followed by a ".", followed by a filename extension of at
        most three characters.
     
        windows 95 supports long filenames by using multiple
        directory entries per file.  the extra entries are hidden.  it
        also automatically derives an 8.3 name for each file for
        backward compatibility so that older versions of dos can
        still access the file.
