title: Airflow FTP connection : Specify default directory
body: <p>How to specify the default directory in the FTP connection in Airflow? </p>
  
  <p>The following fields are available for <strong>Conn Type = FTP</strong></p>
  
  <blockquote>
    <p>Schema<br>
    Port<br>
    Extra</p>
  </blockquote>
  
  <p>The Schema will not work when the directory name is specified there. </p>
  
  <p>I am looking for what key/value pair is required in the Extra field, something like this <a href="https://stackoverflow.com/questions/50151610/airflow-connection-type-file-path?rq=1">(as specified in this post)</a></p>
  
  <blockquote>
    <p>{"path": "/my/path"}</p>
  </blockquote>
  
  <p>I have tried "path", "directory" and "cwd"</p>
  
  <p>What works?</p>
