        NSLog(@"2=%@",[index stringByDeletingLastPathComponent]);

        NSLog(@"3=%@",[index pathExtension]);

        NSLog(@"4=%@",[index stringByDeletingPathExtension]);

        NSLog(@"5=%@",[index stringByAbbreviatingWithTildeInPath]);

        NSLog(@"6=%@",[index stringByExpandingTildeInPath]);

        NSLog(@"7=%@",[index stringByStandardizingPath]);

        NSLog(@"8=%@",[index stringByResolvingSymlinksInPath]);

        NSLog(@"9=%@",[[index lastPathComponent] stringByDeletingPathExtension]);
