FTP Client Engine for C/C++

The FTP Client Engine for C/C++ (FCE4C) is a library of functions providing direct and simple control of the FTP protocol and can be used for both anonymous and private FTP sessions. A simple interface allows connecting to a FTP server, navigating its directory structure, listing files, sending files, deleting files, and receiving files from an application.

The FCE4C library contains both WIN32 and WIN64 Dynamic Link Libraries (DLLs) and can be used with any Windows application capable of calling the Windows API.

The FTP Client Engine for C/C++ supports any version of Microsoft Visual C++, Microsoft Visual Studio, .NET Framework, or most C/C++ compilers.

Example Program

FCE4C provides the functionality to easily and quickly develop software applications that can upload and download files using the FTP library.
