title: Batch file to add character
body: <p>if I have a .txt that has the following: </p>
  
  <p>2005050 "2/19/2005"<br>
  2005060 "3/1/2005"<br>
  2005070 "3/11/2005"<br>
  2005080 "3/21/2005"<br>
  2005090 "3/31/2005"  </p>
  
  <p>Is there a way for the batch file to read and always add .png in the end of a character of 7. </p>
  
  <p>For example.</p>
  
  <p>2005050.png  "2/19/2005"<br>
  2005060.png  "3/1/2005"<br>
  2005070.png  "3/11/2005"<br>
  2005080.png  "3/21/2005"<br>
  2005090.png "3/31/2005"  </p>
