title: Create Azure Function App to clean Temp files of specific app
body: <p>We have several applications on Azure. What we need is to create Function App per Resource group that will, once a day, check specific folders for temporary files and clean them.</p>
  <ul>
  <li>first of all, is there a way to define such function app?</li>
  <li>do we need to create separate function app for each application per resource group? or we can create one function app that will handle all applications per resource group? how we should relate function app to specific web app?</li>
  </ul>
  <p>is there a way to to this without creating function app?</p>
