                foreach (string srcFile in srcFileDialog.FileNames)
                {                
                    string exec = System.IO.Path.GetDirectoryName(Application.ExecutablePath) + @"\OTTO.EXE";
                    string param = srcFile + " -cA";
                    System.Diagnostics.Process.Start(exec, param);
                }
