title: Opening Dot File with OpenXML
body: <p>I need to work on opening a DOT (word document template) file, replace the fillers and save it as Document file.</p>
  
  <p>On opening DOT file I am getting "Document File is Corrupted".</p>
  
  <p>Is it possible to work with DOT file using OpenXML.</p>
  
  <p><strong>UPDATE:</strong> I am saving DOT file as XML (manually using "Save as.."). Renaming file back to dot, so it is XML file built on WordML. Still trying to open it through OpenXML giving me the same error.</p>
