SmartFTP FTP Library 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 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.
