title: Beyond Compare Ignore Unimportant Differences in all files
body: <p>I am using Beyond Compare 3.3.4.</p>
  
  <p>I want to compare a large number of files and ignore unimportant differences.</p>
  
  <p>In <code>Session -&gt; Session Settings -&gt; Comparison tab</code>, the "Requires opening files" section has a "Compare contents - Rules-based comparison". This does what I want when I open each file individually.  The "quick test" section doesn't have this option.  How do I apply rules-based comparisons to my "quick test"? </p>
  
  <p>EDIT:</p>
  
  <p>I am having the same problem as the original poster <a href="http://www.scootersoftware.com/vbulletin/showthread.php?t=5173" rel="nofollow">here</a>.  The answer given was "You can change this by going to the Session menu and changing your Comparison Criteria to use Rules-based content".  Problem is, the "Rules-based comparison" is under the "Requires opening files" section, so this doesn't work.  How do I fix this?</p>
