Question : How to release send file to FTP with more than 1 connection ?

     Hi experts!

  Im using C# 2008 and need to create desktop WinForm  application (DotNET2) that are able to send files via FTP, but with support resume and more interesting  to support send file with 2 , 3 connection or more for faster upload speed.

 I use Catalyst FTP v.6 , it is good and working well but do not support 2 or more connection mode for send files.

 In general  what command are need to be send to FTP server to make this ? Ok .. I can divide files by 2 part and can start in some time this 2 part to be upload to server, what are next ? I do not see command that I need to pass to FTP server which will join this 2 part of 1 file ?

 My FTP server is IIS7 on Win2008 Server.  This future is depend of different FTP server or is standard procedure ?

cute ftp can do this for downloads. it might also do it for uploads, but then its uploading 3 seperate files at a time. this is possible with no problem at all, but you cant split one file into several upload threads unless you have a server application that knows what to do with the commands.

if you want to make more threads, and upload more than one file at a time, this is easily doable.

i dont know catalyst ftp, but if its a .dll file you already create an object, and tell it to upload. simply create 2 objects :)
