Globbing on dos-based systems uses 8.3 notation, which
requires all files to have an extension. All the NT file
system does is layer a long-name database over the 8.3
storage mechanism. To glob all of the files you need to
use "*.*" -- which, of course, breaks *NIX file systems
that don't have built-in extensions.
