FTP

Hi,

I'm writing a java code to transfer and delete remote files using FTP. Basically i'm sending the raw FTP commands (like "DELE") for the transfer/deletion of files. For e.g

sendLine("DELE " + filename);

private void sendLine(String line) throws IOException {
  if (socket == null) {
    throw new IOException("FTP is not connected.");
  }
  try {
    writer.write(line + "\r\n");
    writer.flush();
    if (DEBUG) {
      System.out.println("> " + line);
    }
  } catch (IOException e) {
    socket = null;
    throw e;
  }
}

Now i would like to delete an entire folder. Can someone tell me how i can remove an entire (non-empty) folder? Are there any raw FTP commands to do so? Am quite desperate!
