FileZilla is a free, open-source (GPL) FTP Client for Windows. It supports FTP, SFTP and FTP over SSL.
The main features are the Site Manager, Message Log, File and Folder View, and the Transfer Queue.
The Site Manager allows a user to create a list of FTP sites along with their connection data, such as the port number to use, the protocol to use, and whether to use anonymous or normal logon. For normal logon, the username is saved and optionally the password.
The Message Log is displayed along the top of the window. It displays the console-type output showing the commands sent by FileZilla and the remote server's responses.
The File and Folder View, displayed under the Message Log, provides a graphical interface for FTP. Users can navigate folders and view and alter their contents on both the local and remote machines using an Explorer-style tree interface. Users can drag and drop files between the local and remote computers.
The Transfer Queue, displayed along the bottom of the window, shows the real-time status of each queued or active file transfer.
FileZilla Server is separate executable. It is an FTP server supported by the same project.
FileZilla's source code and downloads are hosted on Source Forge. Source Forge featured FileZilla as the Project of the Month in November 2003.
According to the Help documentation, FileZilla was started as a Computer Science class project in January 2001 by Tim Kosse and two classmates. The alpha version was released in late February 2001, and all required features were implemented by beta 2.1.
