programming flash
1

i am new to flash and am using a template, i designed everything alright but need to know how to click a thumbnail to open a file in the root directory.
The XML file for the thumbnails looks like this currently and everything in the flash movie work and the explorer window opens to he link:

<?xml version=“1.0” encoding=“utf-8”?>
<thumbnails>
<thumbnail filename=“ms.jpg” url=“http://www.myspace.com/XXXX”
title=“XXXX ON MYSPACE”
description=“Come visit us over at our space on MySpace.” />

<thumbnail filename=“flashmo_074_film.jpg” url=“http://www.flashmo.com/preview/flashmo_074_film”
title=“Sample Movie Title Three”
description=“Mauris quis nulla sed ipsum pretium sagittis. Suspendisse feugiat. Ut sodales libero ut odio. Maecenas venenatis metus eu est. In sed risus ac felis varius bibendum.” />

&lt;thumbnail filename="flashmo_073_heart_pink.jpg" url="http://www.flashmo.com/preview/flashmo_073_heart_pink"  
	title="Movie Title Four"
	description="Nulla imperdiet congue metus. Vestibulum dapibus tortor vel orci. Maecenas vulputate, arcu id fermentum eleifend, tortor enim tincidunt mauris, fringilla tincidunt purus urna vel risus." /&gt;

&lt;thumbnail filename="flashmo_072_blue.jpg" url="http://www.flashmo.com/preview/flashmo_072_blue"  
	title="Movie Title Five"
	description="Fusce vulputate tellus ac felis. Praesent mauris. Quisque gravida faucibus ligula. Aliquam magna. Phasellus id felis." /&gt;

</thumbnails>

but instead of a URL I want a file to be opened (a mp3 or wmv or swf or exe) in its own window or default player…What is the code i would use?

A similar flash template would be this

but when you click each of the thumbnails, i want 1 to open a mp3, one ar flash movie etc

thanks
