title: VSTS Release - Delete Azure BLOB Container / Contents
body: <p>I'm using VSTS to deploy an Angular app to blob storage making use of the new static website feature. For this I'm using the <code>Azure File Copy</code> task.
  Since Angular will create new filenames for the different bundles on every build I can't just overwrite the old files, so eventually there will be a lot of old &amp; unsused files in that <code>$web</code> container.</p>
  
  <p>Unfortunately I haven't found a suitable task to do that.</p>
  
  <p>How can I delete or clear out this container in VSTS using the release pipeline before redeploying?</p>
