FileZilla is a free server - and client - software for file transfer using FTP and SFTP . FileZilla is available for the Windows , macOS and Linux operating systems . The source code is under the GNU General Public License (GPL) and is made available via SourceForge .

FileZilla Client

With the FileZilla client, the user can connect to an FTP / SFTP server and then upload and download files. Text files can also be opened in the local text editor . FileZilla then monitors the open file and offers to upload the file if it changes.

FileZilla Portable is a portable edition of the FileZilla client. It enables cross - computer use by means of USB mass storage devices or another portable data carrier and can be used without installation on different computers such as alternately on the laptop , office and home computer .

FileZilla Server

FileZilla Server enables the operation of an FTP server and is a separate program for Windows that is being developed by the same project. In addition to simple user and group management, the software offers SSL / TLS encryption, global and per-user upload / download rate restrictions as well as the option of restricting connections to specific IP addresses on both the client and server side. A so-called remote admin interface also enables maintenance from other computers. Windows 7 (2008 R2) or newer is required to use FileZilla Server. The current version is from February 8, 2017.


From version 2.2.23, FileZilla is based on Unicode , which means that it is no longer compatible with Windows versions prior to Windows XP .

With version 3 FileZilla has been rewritten from scratch and relies on wxWidgets .

From version 3.0.4, the use of FTP proxy servers is possible.

Windows NT and 2000 were supported up to version 3.0.9 . The precompiled files for Mac OS X require Mac OS X 10.5 (Leopard), 10.4 (Tiger) and older require manual compilation .

Version 3.46.0 (dated November 26, 2019) on Mac OS will be the last version that will work on OS 10.11.6. Thereafter, the minimum requirement is OS 10.13.2 (for version 3.46.3, as of January 5, 2020).


SourceForge singled out FileZilla in November 2003 when it was named Project of the Month. FileZilla also won the Community Choice Award in the Network category . Since the start of the project, the software has been downloaded over 414 million times from SourceForge.



At times, the executable FileZilla installer contained third-party adware , as FileZilla participated in a program from the host SourceForge called "DevShare". During installation, the installer downloaded third-party content from third-party websites without being asked, over which neither SourceForge nor Filezilla developer Tim Kosse had control, in order to offer additional third-party software for installation.

Depending on where and how the installer is downloaded, adware is currently (as of early 2020) again contained, then the file name at SourceForge is extended by the word "sponsored". In the standard setting, u. a. the Opera browser installed. This option must be actively deselected to prevent an installation.


The FileZilla client saved the login data (user name and password) up to version 3.26 unencrypted on the hard drive so that they could easily be spied on by third parties or by malware. For this, FileZilla was often criticized by users. With version 3.26, the developers reacted to this criticism and upgraded the program with a master password function. This can be found under Settings, but must be activated by the user himself.
