title: ReportDocument.ExportToDisk() exporting file as .html instead of .htm
body: <p>I have code like this:</p>
  
  <pre><code>        if (ExportFormat == ExportFormatType.HTML32 || ExportFormat == ExportFormatType.HTML40)
          {
              string filename = Path.Combine("C:\exampleFile.htm"));
              _myReport.ExportToDisk(ExportFormat, filename);
          }
  </code></pre>
  
  <p>However, for some strange reason, the file is always exported as .html instead of .htm even though I specified for .htm. Anyone know what causes this? I looked online but couldn't find anything about this.</p>
  
  <p>Thanks!</p>
