        The meta information (long filenames) are special directory
        entries with the "v" (volume label) bit set.  These are
        interlaced with the corresponding short names.  Thus each
        32 bytes of long name becomes one "bogus volume label" adjacent
        to the "real" (short, 8.3, DOS legal) directory entry.

        OS/2 had a more elegant method -- wherein a each directory
        entry used a couple of the "reserved" bytes (directory entries
        only use ~20 of the 32 bytes -- with the extra bytes listed
        in the programming specs as "reserved").  These were used as
        offsets into an "EA DATA" file.  I don't remember whether 
        EA DATA was volume or directory specific -- ISTR that it was
        one EA DATA per volume -- and I think it should have been
        one per directory!

        Linux offers a UMSDOS facility which stores the meta data
        in a hidden file named something like LINUX---.--- (I don't
        remember the exact name -- but it's pretty obvious when you 
        see it).
