Routine Description:

    Builds an array of files in the specified directory, and
    tries to change the attributes of each of these files.
    Does the same thing in all subdirectories, if the "recurse"
    flag was specified in the command line.

Arguments:

    Directory - Pointer to an FSN_DIRECTORY that describes the
                directory to be examined

Return Value:

    Boolean: TRUE if Successful.
