The location where configuration files are saved depends on the operating system FileZilla Server is running on.
- On Debian Linux, the configuration files for the server reside under
/opt/ filezilla-server/etc/and the ones for the Administration interface under ~/.config/filezilla-server-gui, where ~ is the home directory of the user that’s running the FileZilla Server’s Administration interface. - On Windows, the configuration files for the server reside under
%LOCALAPPDATA%\and the Administration interface’ ones under
filezilla-server%LOCALAPPDATA%\filezilla-server-gui, where %LOCALAPPDATA% is the environment variable which expands to the local AppData directory of the user that’s running the FileZilla Server’s service and FileZilla Server’s Administration interface.
On Windows, by default, FileZilla Server’s service runs as the SYSTEM user hence, if the boot drive is C:\, then the configuration files reside under C:\Windows\System32\config\systemprofile\AppData\Local\filezilla-server.
