	echo '<h1>Details of file: ' . $file.'</h1>'; 
	$file = $currentDir.$file;
	echo '<h2>File data</h2>';
	echo 'File last accessed: ' . 
			date('j F Y H:i', fileatime($file)) . '<br>';
	echo 'File last modified: ' .
			date('j F Y H:i', filemtime($file)).'<br>';
	echo 'File type: ' . filetype($file).'<br>';
	echo 'File size: '.filesize($file).' bytes<br>';
	echo '<h2>File tests</h2>';
	echo 'is_dir: ' .
		(is_dir($file)? 'true' : 'false') . '<br>';
	echo 'is_file: ' .
		(is_file($file)? 'true' : 'false').'<br>';
	echo 'is_readable: ' .
