title: MultipartFormDataStreamProvider Cleanup
body: <p>If files are posted to my webapp, then I read them via <code>MultipartFormDataStreamProvider.FileData</code>.</p>
  
  <p>I Initialize the provider like this: </p>
  
  <pre><code>string root = HttpContext.Current.Server.MapPath("~/App_Data");
  var provider = new MultipartFormDataStreamProvider(root);
  </code></pre>
  
  <p>And the provider nicely stores them as "~App_Data/BodyPart_{someguid}"
  But how do I clean up those files after I'm done with them?</p>
