How to upload a file with all entire path?

Question

I would like to drag a file from my computer to my app, and then save its name and its full path.

But I can only retrieve its name and not the full path. How can I do this?

This is the beginning of what I did:

dropZone.addEventListener('drop', function (e) {
        var data = event.dataTransfer.items;
        for (var i = 0; i < data.length; i += 1) {
            var f = data[i].getAsFile();
            var name = f.name;
        }
}

Thank U.
