FileZilla is free and cross-platform FTP software, consisting of FileZilla Client and FileZilla Server. Binaries are available for Windows, Linux, and Mac OS X. It supports FTP, SFTP, and FTPS (FTP over SSL/TLS). As of 18 April 2011, FileZilla Client was the 7th most popular download of all time from SourceForge.net. Support for SFTP (SSH File Transfer Protocol) is not implemented in Filezilla Server.
FileZilla was started as a computer science class project in the second week of January 2001 by Tim Kosse and two classmates. Before they started to write the code, they discussed on which licence they should release the code. They decided to make FileZilla an open-source project, because there were already many FTP clients available and they didn't think that they would sell a single copy if they made FileZilla commercial.
In May 2008 Chris Foresman assessed FTP clients for Ars Technica, saying of FileZilla: "Some friends in the tech support world often recommend the free and open-source FileZilla, which offers a Mac OS X version in addition to Windows and Linux. But I've never been thrilled about its busy interface, which can be daunting for novice users."
Writing for Ars Technica in August 2008 Emil Protalinski said: "this week's free, third-party application recommendation is FileZilla.... This FTP client is very quick and is regularly updated. It may not have a beautiful GUI, but it certainly is fast and has never let me down."
In January 2012 cNet.com gave FileZilla their highest rating of spectacular, 5 out of 5 stars.
From version 3 onwards, Filezilla stores all saved usernames and passwords as plain text files. This allows any malware that has gained access to the user's system to simply read the data stored in these files and to remotely transfer this data to the attacker. FileZilla's author responded to such criticism saying "If your system is secure, you can use nuclear missile launch codes as desktop background."
The practice of saving plaintext passwords is, however, sometimes considered a better practice than a false sense of security, as some people characterize the effects of password encryption.
Storing encrypted private key files is still supported in current versions, as well as using ssh-agent, in the same way as previous versions of Filezilla. Private key authentication is usually recommended over password-based authentication.
