I use emacs-23.2 with command line interface of everything search engine
from http://www.voidtools.com (es.exe) as locate command under MS
Windows XP.

Yes, that is correct. 

The second culprit is `directory-listing-before-filename-regex', which
is to restrict and cause fails under Windoze. Under Linux leads the
restricted regexp only to incorrect display (the point is always after
the first slash character).

I tested the simplyfied version of
`directory-listing-before-filename-regex' under Windoze with everything
(es.exe)m and Linux with GNU locate and it works well.

Hmm. I'm not sure. How about an UNC path ala \\sever\share\path?

If emacs correctly resolve an UNC path with forward slashes so i would
agree.

See above.
