Bob,
    Two things -
(1)
It reports well on the named directory but i t doesn't scan sub-dirs in its
present form!
In the line:

 // then recurse through all the subfolders
        while (!done)
        {
            if(  (fb.ff_attrib&FA_DIREC) ==FA_DIREC )

fb.ff_attrib is always a space (32).

(2) We need the full address of found files to be returned.

Hope you can help just this once more!..

Georges.

ps - I've substituted 'FindClose' for 'findclose' as that was not known.
