watcher = new FileSystemWatcher(folder);
watcher.NotifyFilter = NotifyFilters.Size;

You indeed need a thread that would open all files and read a byte from them, my program stopped working after I ran it on Windows 7 instead of XP, I used the following code

private void SingleByteReadThread(object notUsed)
    {
       while (true)
      {
         foreach (FileInfo fi in new DirectoryEnumerator(folderPath))
                  {
                      using (FileStream fs = new FileStream(fi.FullName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
                          fs.ReadByte();    
                  }

          Thread.Sleep(TimeSpan.FromSeconds(2));
      }
  }

DirectoryEnumerator is my own class
