FileZilla is free software which lets you transfer files over the internet.
Consisting of FileZilla Client and FileZilla Server, FileZilla is defined as a free software, cross-platform FTP application.
Available for Windows, Linux and MacOS, FileZilla allows users to transfer files over the Internet.
The software started life as a computer science class project by Tim Kosse and two classmates. They decided to make the software open-source as they believed that no one would buy it if they made FileZilla commercial.
