It can be done by creating a blob using the file source URL. I have tested this with image and PDF files in IE 11.

                if (navigator.msSaveBlob) {
                    var xhr = new XMLHttpRequest();
                    xhr.open('GET', file_url, true);
                    xhr.responseType = 'blob';

                    xhr.onload = function(e) {
                       if (this.status == 200) {
                           var blob = this.response;
                           navigator.msSaveBlob(blob, file_name);
                       }
                    }

                    xhr.onerror = function(e) {
                        alert("Error " + e.target.status + " occurred while receiving the document.");
                    }

                    xhr.send();
                }

I got this idea when I came across this: Getting BLOB data from XHR request
