FileZilla
free and cross-platform FTP software
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. Professional editions of both the client and server offer additional features.
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.
The public source identifies “FileZilla” as free and cross-platform FTP software. This brief keeps that definition visible, then builds a research path around FileZilla, free and cross-platform.
Why this record matters
A short description can identify a subject without explaining its stakes. For “FileZilla”, the useful work is to connect “free and cross-platform FTP software” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q300662. 2 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2001 and 2003.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
