Below is the code i used to write the file on my destination folder , howerver by some logic if same file i want to create having some different data into it , it gets overwritten on that location , my requirement is not to overwrite the file , but keep the old file as it is and creating new file having similar name but buy just appending next copy to it .. ex my_file.pdf(1) or something like that

ProcessStartInfo startInfo = new ProcessStartInfo();
                    string switches = "";
                    switches += "--header-html " + path + " --footer-html " + footerPath;// + " --header-spacing 10";
                    startInfo.UseShellExecute = false;

                    startInfo.RedirectStandardOutput = true;

                    startInfo.RedirectStandardInput = true;

                    startInfo.RedirectStandardError = true;

                    startInfo.CreateNoWindow = true;

                    startInfo.FileName = Server.MapPath(ConfigurationManager.AppSettings["wkhtmltopdfsetup"].ToString());

                    startInfo.Arguments = switches + " " + website + " " + destinationFile;



                    Process myProcess = Process.Start(startInfo);
                    string error = myProcess.StandardError.ReadToEnd();
                    myProcess.WaitForExit();
                    myProcess.Close();
                    myProcess.Dispose();
                    myProcess = null;
