Javascript cannot access file system, you cannot use ajax to download files. Try using an iframe pointing to the file to download it.

<iframe id="downloadFrame" style="display:none"/>

When you need to download, use this script:

var iframe = document.getElementById("downloadFrame");
iframe.src = "yourpathtofile";

If you use jQuery, you can try:

$("#downloadFrame").attr("src","yourpathtofile");

Another solution is using window.open

window.open("pathtoyourfle");
