Prompting a button to download a file

is it possible to prompt a button to download a zip file in flash?? I have a lot of files, .ppt, .doc, and .pdfs that i want to open externally in their respective applications. Here is teh code i am using on their buttons

on (release) {
//Goto Webpage Behavior
getURL(“file:///Macintosh%20HD/Users/trecauser/Desktop/catc_menu/cd/mm/success_stories/michael_seare.pdf”,"_blank");
//End Behavior

}

What should i do? thanks…
