FileZilla is a free and open-source, cross-platform FTP application, consisting of FileZilla Client and FileZilla Server. Clients are available for Windows, Linux, and macOS. Both server and client support FTP and FTPS (FTP over SSL/TLS), while the client can in addition connect to SFTP servers. FileZilla's source code is hosted on SourceForge.

History

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 under which license they should release it. They decided to make FileZilla an open-source project because many FTP clients were already available, and they didn't think that they would sell a single copy if they made FileZilla commercial. Since its initial development in 2001, FileZilla has been released under the GNU General Public License (GPL). The FileZilla client is currently released under GPL-2.0-or-later, and the server package under AGPL-3.0-or-later.

FileZilla featured as SourceForge's Project of the Month in November 2003.

Features

FileZilla Client allows file transfer using both FTP and encrypted FTP such as FTPS (server and client) and SFTP, with support for IPv6. One of its most notable features is its capability to pause and resume file transfer processes, even for files larger than 4GB. Users can chose to overwrite existing files based on the age or size of the file. It also allows the preservation of timestamps on transferred files, provided there is support from the local system when downloading or from the target server when uploading.

FileZilla Client uses a tabbed user interface for multitasking, allowing users to browse more than one server or transfer files simultaneously between multiple servers. It also features a Site Manager to manage server lists and a transfer queue for ordering file transfer tasks. It has bookmarks for easy access and supports drag and drop for downloads and uploads. The software provides directory comparison for comparing local files and server files in the same directory. If there is a difference in the file details, such as a mismatch in name or size, the software will highlight the file in colour.

Other features include configurable transfer speed limits, filename filters, a network configuration wizard, remote file editing, keep-alive command to prevent disconnections when idle, HTTP/1.1, SOCKS5 and FTP-Proxy support, and logging events to a file for debugging. Additionally, users can export queues into an XML format file, browse directories synchronously, and remotely search for files on the server.

FileZilla Client is a cross-platform software, runs on Windows, Linux, *BSD, and Mac OS X, and available in 47 languages worldwide, including Arabic, Armenian, Basque, Bulgarian, Catalan, Chinese, Corsican, Croatian, Czech, Danish, Dutch, German, Greek, Estonian, Finnish, French, Galician, Hebrew, Hungarian, Indonesian, Icelandic, Italian, Japanese, Georgian, Khmer, Korean, Kurdish, Kyrgyz, Lithuanian, Latvian, Macedonian, Norwegian, Nepali, Occitan, Persian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Thai, Turkish, Ukrainian, and Vietnamese.

These are some features of FileZilla Server:

• FTP and FTP over TLS (FTPS)
• IPv6 support
• Speed limits
