title: PL/SQL delete static workspace file
body: <p>I've been searching on google and still not found anything.</p>
  <p>Is there any possible way to delete a file from the Static Workspace Files within the database?</p>
  <p>For example you can remove a file from the Static Application Files with this procedure <code>wwv_flow_api.remove_app_static_file</code></p>
  <p>Regards</p>
