UTF-8 support in FileZilla Server 0.9.15

FileZilla Server now uses UTF-8 encoding for filenames as specified in RFC 2640 ( This allows for proper handling of filenames containing non-English characters, as FTP originally was only designed for 7-bit US-ASCII.
In order to support UTF-8, FileZilla Server now requires at least Windows 2000 or higher, Windows 98 is no longer supported.

You might have problems with some non-UTF8 capable clients that do now support RFC 2640. In this case I recommend to use FileZilla as client, it supports UTF-8.

Security update in FileZilla Server 0.9.9

Recently a security vulnerability has been discovered in zlib which could allow remote code execution under some circumstances.
Remote code execution was not possible with FileZilla Server since zlib was compiled with enabled buffer overflow protection, instead FileZilla Server did just terminate.

Version 0.9.9 fixes this problem, an update is highly recommended.

The problem seems to only occur on Windows 2000 or older.... read more

FileZilla 2.2.5 final released, FZ 3 development started

With version 2.2.5, an era ends. This will be the last version based on the old source tree. Over the last three years, FileZilla has been constantly improved. However, in the past few months development has slowed significantly, mainly due to the fact that it's become quite difficult to add new features to FileZilla. The complexity of FileZilla has grown far far beyond anything then anyone could imagine when the project first started, this also reflects in the source code. That's why I've decided to leave the current source tree behind and start FZ3 from scratch. The new version will contain most if not all features of FileZilla 2.2.5 once done and will be cross-platform.... read more

Help wanted to create makefiles/configure scripts

In order to create the upcoming cross-platform version of FileZilla 3 (, I'm searching for a developer which knows how to use automake, autoconf and the like to create the neccessary input files for these tools.

Structure of the project:
FZ3 is divided into two parts, the engine and the interface, located in the src/engine and src/interface subfolders.
The engine should be compiled as static library and the interface links to it. Common for both is a shared include folder located in src/include.... read more
