Download files in Assets fields
Change the javascript of the asset file to something like this and it will work

$(function(){
    $(".field .input .elementselect .element:not(.linked)").each(function(){
        var $this = $(this);
        if (!$this.data("url")) { return false; }
        var $a = $("&lt;a class='icon'&gt; &lt;/a&gt;")
            .attr("href", $this.data("url"))
            .attr("title", "Download")
            .addClass("download")
            .addClass("sharebtn")
            .addClass("icon")
            .attr('download', $this.data('label'))
            .appendTo($this);
        $this
            .addClass("linked")
            .prepend($a);
    })
});
