libfilezilla offers a lightweight, powerful library for developers who need efficient file transfer capabilities within their applications.

The libfilezilla library is a small, yet powerful C++ library for building FTP, FTPS and SFTP client applications. It was created by Tim Kosse, a software developer with over 20 years of experience in programming.

One of the main features of libfilezilla is its cross-platform compatibility. It runs on most popular operating systems, including Windows, macOS, and Linux. This makes it an ideal choice for developers who want to create software that can be used across multiple platforms.

The library provides a simple API for connecting to FTP, FTPS, and SFTP servers, as well as uploading and downloading files from these servers. It also includes support for resuming interrupted transfers and performing directory listings.

Another important feature of libfilezilla is its security. The library uses modern cryptographic algorithms to ensure that all data transferred to and from the server is encrypted. It also includes built-in support for TLS/SSL connections.

libfilezilla is an excellent choice for developers who want to create robust, secure, and cross-platform FTP, FTPS, and SFTP client applications.
