title: mstest how to prevent custom log file from being DELETED (and prevent .trx from being deleted too)
body: <p>In a Micorosoft MSTest, I am creating a custom log file (.xlsx) dynamically in  unit tests in <code>ClassInitialize</code> and closing it in <code>ClassCleanup</code>. It gets created and populated but then when the tests have finished running, the log file in the out directory is somehow getting deleted.</p>
  
  <p>Any ideas on how to prevent this log file and other files in the <code>TestResults/Out directory</code> from being deleted?  </p>
  
  <p>example location: </p>

  <p>Microsoft MSTest 2012 and Selenium WebDriver are being used.  The test is being run from Visual Studio 2012 by selecting <code>Test--&gt; Debug--&gt;All Tests</code></p>
