title: Window extraction alert is flashing with EXTRAC32 command in batch
body: <p>I want to suppress the &quot;Extraction CAB&quot; or &quot;Extracting CAB&quot; window that appears during some brief <em>100 microseconds</em> when I extract a compressed file, as shown below. I tried to redirect messages to <code>nul</code>, but the window flashes anyway. I don´t want to use other extractors as 7Zip or such.</p>
  <p>Any ideas to get rid of that window?</p>
  <pre><code>@echo off    
  set u=d:\myfolder1\myfolder2\myfolder3\myfolder4
  cmd /c &quot;&quot;extrac32&quot; &quot;my.cab&quot; /L %u% &gt;nul: 2&gt;nul:&quot; &amp; del my.cab
  </code></pre>
  <p>I have also used the <code>/Y /L</code> option, to no avail.</p>
  <p><strong>Annoying window flashes and, then, closes</strong></p>
