What is Colorado FTP?

ColoradoFTP is the open source Java FTP server. It is fast, reliable and extendable. Fully compatible with RFC 959 and RFC 3659 (File Transfer Protocol and Extensions) this implementation makes it easy to extend the functionality with virtually any feature. Well commented source code and existing plug-ins make it possible to shape the FTP server just the way you want! Run it on any platform featuring the latest Java VM – Windows, Linux, Unix etc.
