    /* Print out information on every file in the subdirectory "subdir". */
    if( f_findfirst( "/subdir/*.*", &xFindStruct ) == F_NO_ERROR )
            printf( filename:%s, xFindStruct.filename );

            if( ( xFindStruct.attr & F_ATTR_DIR ) != 0 )
                printf ( "is a directory directory\r\n" );
                printf ( "is a file of size %d\r\n", xFindStruct.filesize );
