title: File.Exists false when created by tesseract
body: <p>I use tesseract to get text from captcha image.
  I use this code </p>
  
  <pre><code>Process p = new Process();
  p.StartInfo.FileName = Server.MapPath("~/app/tesseract.exe");
  p.StartInfo.Arguments = imgSavePath + " " + txtSavePath;
  p.Start();
  p.WaitForExit();
  bool exist = File.Exists(txtSavePath);
  </code></pre>
  
  <p>The <strong>txtSavePath</strong> is created in windows explorer, i can open it and can read the text in it. But the <strong>exist</strong> variable is <strong>false</strong>. It is so strange. 
  Can anybody tell me why? How can i use <strong>StreamReader</strong> to read text in created file?</p>
