title: Creating a folder at build Electron
body: <p>I'm looking to make a folder outside of a portable electron build. </p>
  
  <p>I'm thinking that creating the folder when the app starts will trigger permissions so I'm hoping to find a way to do it within the build process. </p>
  
  <p>I'm using electron-build for packaging the app. </p>
  
  <p>What's the best way to do that?</p>
