                { // Here we ignore some file names like [.]  [..] and Thumbs.db files/folders
				
				// Now we print the hyperlinked list of files/folders 
				// <a> tag is for links
				// <br> tag is for line feeds.
                    echo '<a target="_blank" href="'.$folder.$file.'">'.$file.'</a><br>'."\n";

        }
    }
}  // End of List Files In directory function
 
// Let Us call the function and see how it goes!
