                 #region start Processing

                foreach (string tempInput in tmpfiles)


                   FileStream inputfiles = new FileStream(tempInput, FileMode.Open);

                    CopyStream(output, inputfiles);


                #endregion start Processing



void CopyStream(Stream destination, Stream source)


            int count;

            byte[] buffer = new byte[BUFFER_SIZE];
