Module Name:

        dir.hxx

Abstract:

        This module contains the declaration for the FSN_DIRECTORY class.
        FSN_DIRECTORY is derived from the abstract FSNODE class. It offers an
        interface which supports the manipulation of DIRECTORIES. It's primary
        purpose is to support the creation of lists of FSNODE (e.g. FILE and
        DIRECTORY) objects that meet some criteria (see FSN_FILETER)and to
        manipulate (e.g. copy, move) FSNODEs which are 'owned' by a FSN_DIRECTORY.
