Official direct download server:

FileZilla Client:

Just for information, no links:
Windows 95C - last working Filezilla 2.2.18
Windows 98/SE/ME - last working Filezilla 2.2.22
Windows 2000 - last official working version is
The version 3.8.0 seems to work fine on Windows 2000 (I'm using it), but only basic functionality has been tested. Higher versions fail to run.
If FileZilla freezes itself or even the OS right after the start, you must disable automatic updates. See ... 733#p51733 . I recommend to disable automatic updates via an fzdefaults.xml file. You can either create your own, see the fzdefaults.xml.example file that got installed with FileZilla, or use the one I've attached to this post (dump the file into the program directory of FileZilla).

Windows XP SP3 - latest version officially working is 3.8.0, but there are BSOD crashes for some users. The reason is unknown, a fix unlikely. If you are affected, use version 3.7.3 on XP and disable updates. Note you won't receive support after April 8th, 2014. FileZilla 3.8.1 and onward might not run at all on all 5.x kernel OS (2000/XP/XPx64/Server 2003)! If you feel adventurous, try it anyway, runs fine on my XPs, with minor issues (missing drive icons).
Update: FileZilla is the last version running on XP, or higher doesn't start.

As FileZilla 2.2.32 seems to have disappeared from the Sourceforge list, here the download link for anyone still needing it: ... _setup.exe (only transition to v3 supported) ...
Legacy version, don't ask for support on the forums, you are on your own. Don't blame us if you run into problems.

Here you'll find unofficial binaries for Mac OS X 10.4 Tiger:

FileZilla Server:

FileZilla Server works under Windows Vista and up (both x86 and x86_64). IPv6 functionality requires activated IPv6 functionality.
Last official Windows XP version is 0.9.42, but 0.9.43 also seems to work.
The last version that worked for Windows 9x/ME was 0.9.14a IIRC, as it was the last version that didn't use UTF-8/Unicode.
While FileZilla Server 0.9.41 works on Windows 2000 (official final: 0.9.37), it's not guaranteed to stay this way. Note: Both versions suffer from the Remote Alias renaming vulnerability that 0.9.43 fixed.
Note that Win2000 IPv6 support requires the MSRIPv6Kit to be installed (MS Download).

Important information: If the system's CPU does not support the SSE2 instruction set the official 0.9.43 and beyond versions of FileZilla Server might crash and not run at all. That issue is associated with usage of an updated compiler. Your only options are using 0.9.42 (which has a vulnerability concerning remote Alias renaming), compiling it yourself for arch IA-32/SSE, or using a different server altogether. :(


Heartbleed exploit:

FileZilla Server makes use of OpenSSL. The current version 0.9.45 fixes the Heartbleed exploit that occured with OpenSSL 1.0.1f or earlier. The last working XP version 0.9.43 is vulnerable, unless you replace the libeay32.dll and ssleay32.dll files with the versions from 0.9.45 (also fixes another OpenSSL issue). Such a 0.9.43 with SSL backport from 0.9.45 seems to be safe. Version number of both DLLs must be, at least.

File comment: XML control file that disables any update functionality from within FileZilla Client.

SSE2 requirement

In the near future FileZilla will require a CPU with SSE2 support. As a rule of thumb, any CPU that can run Windows 8 is fine. On any other CPU starting FileZilla will immediately crash with error 0x0000001d.
Find out about your CPU's SSE2 (non-)support by using the Sysinternals "CoreInfo" tool.

FTP connection problems? Do yourself a favor and read Network Configuration.
All FileZilla products fully support IPv6.
All support requests per PM will be ignored!
