Thank you so much Jerry for your support.
I did this by creating one "index.html" file in parent folder and redirected to the required page by java script coding from index.html .
index.html :-
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
<script type="text/javascript">
window.location.replace("absolute path of required file/xxx.html");
</script>
</head>
<body>
</body>
</html>
