title: Spring Integration SFTP: removing or noving multiple files
body: <p>With Spring Integration I want to move or remove multiple files or non-empty folders at once on a remote SFTP server. But I can't seem to find support for this in the official <a href="http://docs.spring.io/spring-integration/reference/html/sftp.html" rel="nofollow">Spring docs</a>, as it seems that this is unsupported. Although the documentation isn't always correct anyway.</p>
  
  <p>I was thinking by using the <code>int-sftp:outbound-gateway</code> with the <code>rm</code> command with a payload the directory name. But it doesn't seem to work. I haven't tried it with <code>mv</code> yet, but I'm wondering if anyone has any experience with this behaviour in Spring Integration.</p>
