Copy folder with progressbar

Strange task, but if you want so…

;)

         private void button1_Click(object sender, EventArgs e)

                {

                      FileStream readerStream = new FileStream("c:\\testBig.txt", FileMode.Open, FileAccess.Read);

                      FileStream writerStream = new FileStream("d:\\testBig.txt", FileMode.OpenOrCreate, FileAccess.Write);

                      int index = 0;

                      byte[] buffByte = new byte[100];

                      do

                      {

                                this.Text = index.ToString(); // here you indication

                                Application.DoEvents();

                                index += 100;

                                readerStream.Read(buffByte, 0, buffByte.Length);

                                writerStream.Write(buffByte, 0, buffByte.Length);

                      }

                      while (readerStream.Length > readerStream.Position);

                      writerStream.Flush();

                      writerStream.Close();

                      readerStream.Close();

                }

If you want to increase speed – enlarge the size of buffByte.
