Overview
Overview

 

Introduction 

The SmartFTP FTP Library component (COM) provides file transfer functionality for the FTP protocol. It offers a wide range of features which allows reliable and secure file transfers (TLS). The component takes advantage of the COM technology which makes it possible to use it in numerous environments as Visual Basic, Visual C++, JavaScript/VBScript, VB.NET, C#.NET, Delphi, etc.

  • Rename, Make and Remove Directory
  • Move/Rename and Delete File
  • IPv4 and IPv6
  • International Domain Names (IDN)
  • UTF8 / Unicode Support
  • SOCKS4, SOCKS4A, SOCKS5, HTTP Proxy Support
  • Support for 64-bit File Size
