CFtpServer is a cross-platform C++ class which allows developers to use a simple, fast, and reliable FTP server within their program.
Warning: project development stopped back in 2010 and I am not maintaining the project anymore. There are a few issues with the code, as can be seen on the tracker.
Cftpserver works fine.
Easy to use and works.
Clear and logical C++ wrapper for full FTP server functions. Windows and Linux compatible. Can be used to cook a secret ftp server or one with GUI easily. The code is robust and reliable. :) Waitting for IPV6 compatibility and virtual file system which the author promised. :)
