title: GetFileAttributes inconsistency -- why?
body: <p>Why does the following:</p>
  
  <pre><code>GetFileAttributes(L"D:");
  </code></pre>
  
  <p>return <code>0x00002010</code>, but the following on the exact same machine:</p>
  
  <pre><code>GetFileAttributes(L"\\\\?\\D:");
  </code></pre>
  
  <p>returns <code>INVALID_FILE_ATTRIBUTES</code> and error code <code>ERROR_INVALID_PARAMETER</code>?</p>
