Description: The FTP Voyager Software Development Kit (SDK) has been designed to give you easy, flexible, and powerful control over FTP connections and file transfers. When you use the FTP Voyager SDK, you are using the same FTP client engine that FTP Voyager uses: FtpTree ActiveX Control. The FTP Voyager SDK "wraps" the FtpTree ActiveX Control in a number of functions to make implementation relatively painless and yet powerful.
