title: Location of Extension Manifest [package.json] file on VS Code
body: <p>[I use macOS]</p>
  
  <p>I have an extension called Code Runner:
  <a href="https://marketplace.visualstudio.com/items?itemName=formulahendry.code-runner" rel="nofollow noreferrer">https://marketplace.visualstudio.com/items?itemName=formulahendry.code-runner</a>
  All I want to do is clear output everytime I execute some C++.So I found this command online:</p>
  
  <pre class="lang-json prettyprint-override"><code>"code-runner.clearPreviousOutput": true
  </code></pre>
  
  <p>But I am unable to fund where to enter it.I think its the package.json file,but I am unable to located.This is very trivial but its really annoying me!</p>
