FileZilla is a popular open source file transfer client program that provides an easy to use graphical user interface, restores interrupted file transfers, and supports SFTP (SSH File Transfer Protocol). Administration of multiple FTP sources and support for firewalls are provided as well. It is available for all major platforms and supports multiple languages.
FileZilla makes it easy to synchronize for example web site directories on remote servers with copies on your local computer. Complete folders can be uploaded or downloaded with simple drag-and-drop, or cut-and-paste operations. Since 2001 it has been downloaded more than 16 million times and is already included in many Linux distributions
FTP is a file transfer protocol that was developed when the first computer networks were designed. It uses the client-server communication model where one computer continuously runs a "server" program that waits for requests from a "client" program.
Command line FTP clients are included in pretty much all operating systems. There are also a variety of FTP clients with graphical user interfaces available, such as the FileZilla Client. Luckily, there is also a FileZilla Server program that is easy to set up. So you can turn any Windows computer into an FTP server and access it from any other computer on the Internet.
Like FileZilla Client, FileZilla Server is free and open source. You can download it from FileZilla and set it up using a straight forward set-up wizard. You can choose to have the server start automatically when the computer is turn on, or you can choose to start it manually.
Once the server is up and running you need to use the administrative client to set up at least one user account, which is needed to remotely log in. Now you can also automate routine file transfer operations using shell scripts and the .netrc file that defines auto-login and configuration information for FTP clients.
