Okay, well I guess I've taken the incorrect approach entirely. My intention was to enable the user to download the file from the servers hard-drive. My treeview contains the current file structure for a directory on the server, and I would like to enable users to download any file present.
My basic server folder structure looks like.
WWW Directory (Where site is hosted)
window.open(serverFileAddress, 'Download');<br />
serverFileAddress will return the proper download if navigated to through the url address.
