[3] shows an MS-DOS window on a Win98 desktop, having just run the
"dir" command. In the background is a Win98 explorer window, for
comparison with the dir command.
Neither of the two ways of listing the contents of a directory show
any filenames for <illegal 8.3, long name present> entries as produced
by tridge's vfat patches.

As the filename and the intro text had said..

[4] 16-bit program (Windows 3.x era) running on XP (but probably also
happens earlier). File dialog shows blank line where an entry has an
illegal 8.3 name; also as a result of the vfat aptches.
