title: what mongo files should not be tracked by git
body: <p>I've installed <code>MongoDB</code> in my <code>git</code> repository and configured <code>dbpath</code> to <code>./data/db</code>. (Basically inside <code>bin</code> folder)</p>
  
  <p>It added (aside standard <code>.exe</code> files) files with extensions <code>.wt</code>, <code>.lock</code> and etc.</p>
  
  <p>What files I can safely add to <code>gitignore</code>?</p>
