Xceed FTP Library is an ActiveX control that allows developers to add FTP file transfer capabilities to their applications. The library provides access to the complete functionality of the FTP protocol. Sending and receiving one or more files can be accomplished with only a single line of code. Adding a few extra lines will allow developers to accomplish everything else - even to build a full-featured FTP client like "CuteFTP". A sample FTP client with fully commented source code is included with the library, along with many other samples in various languages. The Xceed FTP Library is the only library that takes full advantage of the Winsock-2 networking API, including taking advantage of overlapped I/O and using I/O completion ports when running on Windows NT or 2000. The FTP Library's I/O engine is based on our highly-optimized Xceed Winsock Library which translates to low processor overhead for your file transfers, is feature rich and firewall friendly, can work in the background and uses Winsock-2 for best performance.
