  Frank,

  You can use the code below. Let me know if you have any questions

  using System;
  using System.Collections.Generic;
  using System.Text;
  using System.IO;

  namespace DirectoryBrowser
  {
      class EntryPoint
      {
          static void Main(string[] args)
          {
              string directory        = @"C:\test";
              string searchPattern    = "*.txt"; //searches for files ending with .txt
                                               //Can be replaces with * to search all files
              string searchValue      = "0X0D";
              StreamReader reader     = null;
              StreamWriter writer     = null;

              if (Directory.Exists(directory))
              {
                  /* Get all the files in the directory
                   * Note: If the are sub directories, you may want to get the sub diectories and iterate through them
                   */
                  FileInfo[] files = new DirectoryInfo(directory).GetFiles(searchPattern); //replace with new DirectoryInfo(directory).GetFiles() if searchPattern is not needed

                  //Read each file in the directory and check the contents.
                  foreach (FileInfo file in files)
                  {
                      reader = file.OpenText();
                      string content = reader.ReadToEnd();
                      reader.Close();
                      if (!content.EndsWith(searchValue))
                      {
                          writer = file.AppendText();
                          writer.WriteLine(searchValue);
                          writer.Flush();
                          writer.Close();
                      }
                  }
              }

              if (reader != null)
                  reader.Dispose();

              if (writer != null)
                  writer.Dispose();
          }
      }
  }
