title: FTP directory partial listing with wildcards
body: <p>First I asked that: <a href="https://stackoverflow.com/questions/9230485/ftp-directory-listing-timeout-huge-number-of-subdirs">ftp directory listing timeout. Huge number of subdirs</a>. I got the answer.</p>
  
  <p>Still because I can have hundred thousands of FTP objects in the directory it could take really long time to scan that. However I thought it might be possible to retrieve all the objects that begin with 'A' and then 'B' and so on... As it retrieves directories it could start processing them on the other thread without waiting till it gets the entire list.</p>
  
  <p>Is it possible to do FTP directory listing with wildcards using standard <code>FtpWebRequest</code>?</p>
