title: fileName to retrieve multiple file names
body: <p>How do I get apache camel to fetch multiple files using <code>fileName</code> on the file component.  Here is my route:</p>
  
  <p><code>sftp://ftpserver:22/?username=blah&amp;password=blah&amp;stepwise=false&amp;useList=false&amp;ignoreFileNotFoundOrPermissionError=true&amp;fileName=${file:onlyname.noext}.txt&amp;delete=true&amp;doneFileName=done")</code></p>
  
  <p>The files that are on the ftp server are <code>1.txt</code>, <code>2.txt</code>, <code>3.txt</code>. How do I retrieve all of them without having to do a fixed <code>fileName</code> such as <code>fileName=3.txt</code>?</p>
