SmartFTP FTP Library 2.0

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