      FileInputStream inputStream = new FileInputStream(source);
      //Creating an FileOutputStream object
      FileOutputStream outputStream = new FileOutputStream(destination);
      //Creating a buffer to hold the data
      int length = (int) source.length();
      byte[] buffer = new byte[length];
      while ((length = inputStream.read(buffer)) > 0) {
         outputStream.write(buffer, 0, length);
      }
