Use Script Task and download files into your file system. Eg(from MSDN):
using System;
using System.IO;
using System.Net;
using System.Text;
namespace FTPExample
{
public class WebRequestGetExample
{
public static void Main ()
{
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/test.htm");
request.Method = WebRequestMethods.Ftp.DownloadFile;
request.Credentials = new NetworkCredential ("anonymous","janeDoe@contoso.com");
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);
Console.WriteLine(reader.ReadToEnd());
Console.WriteLine("Download Complete, status {0}", response.StatusDescription);
reader.Close();
response.Close();
}
}
}
