Arnaldo,

There are several small code libraries available on C-SharpCorner (www.c-sharpcorner.com). You can go up there and search on FTP and find some utilities that others have written.

There may be similar utilities on other .NET sites, such as the Code Project (www.codeproject.com), GotDotNet, etc.

Also, Mabry Software has a very good set of commercial tools. I've used Mabry for years. They have an FTP control for .NET. (www.mabry.com)

Hope that helps...
Kevin
