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 strong.
The FTP Voyager Software Development Kit 15.1 (SDK) allows you to power your application's FTP abilities with same engine used in the FTP Voyager client. The SDK exposes FTP Voyager's FTP abilities through a thoroughly documented and easy to integrate DLL. This flexible interface gives you the capability to use the SDK in your existing applications with a minimal amount of effort.
Virtually all functionality displayed by FTP Voyager is accessible to your software through the SDK. This includes on-the-fly data compression, secure file transfers using FTP over SSL, folder synchronization, file transfer integrity checking through XCRC, and detailed logging of its activities. The FTP Voyager SDK's modular design for handling file transfers allows you to use the SDK at a high level to transfer files through a few simple functions, or you can choose to work with the SDK at a lower level to receive data in chunks or even directory listings one at a time.
FTP Voyager as an FTP client is known for its rock-solid stability, fast and secure file transfers, and simple, yet strong interface. The FTP Voyager SDK allows you to bring all these advantages to your application's file transfers as well.
