注意：　

Note that is unit is simply for listing ALL FTP List parsers in Indy. //此单元 只用于列出Indy中的所有FTP列表解析器。
The user could then add this unit to a uses clause in their program and // 用户可以将这个单元添加到程序中的uses子句中，然后
have all FTP list parsers linked into their program.  //将所有FTP列表分析器链接到它们的程序中。

如果不uses 会发现 属性带出的 ItemType 属性都不准确，都会显示 ditFile，以下亲测代码，供参考：

var
  t:TIdFTPListItem;
begin
    t:=IdFTP1.DirectoryListing.Items[ListBox1.ItemIndex];
    ShowMessage(t.FileName);
    case t.ItemType of
      ditDirectory:  ShowMessage('ditDirectory');
      ditFile:  ShowMessage('ditFile');
      ditSymbolicLink:  ShowMessage('ditSymbolicLink');
      ditSymbolicLinkDir:  ShowMessage('ditSymbolicLinkDir');
      ditBlockDev:  ShowMessage('ditBlockDev');
      ditCharDev:  ShowMessage('ditCharDev');
      ditFIFO:  ShowMessage('ditFIFO');
      ditSocket:  ShowMessage('ditSocket');
    end;
end;
