 URL website = new URL(path);
 ReadableByteChannel rbc = Channels.newChannel(website.openStream());
 FileOutputStream fos = new FileOutputStream(filename);
 fos.getChannel().transferFrom(rbc, 0, 1 << 24);
 } catch (IOException ex) {
 Logger.getLogger(main.class.getName()).log(Level.SEVERE, null, ex);
 }

 return path + "............ COMPLETED!";
