How to Change where Configuration Files are Stored

FileZilla Server’s service accepts a --config-dir parameter. You can use this parameter when starting the service.

• On Windows, to relocate the configuration files in your folder of choice, open a cmd
  console with Administrator privileges and run the following command.

  sc config filezilla-server binpath= "\"\filezilla-server.
exe\" --config-dir \"\""

  Where is the folder where FileZilla Server was installed into and
  is the absolute path to your folder of choice.

  For example, to store the files under FileZilla Server’s installation folder, and FileZilla Server is installed under C:\Program Files\FileZilla Server, the command should be:

  sc config filezilla-server binpath= "\"C:\Program Files\FileZilla Server\
filezilla-server.exe\" --config-dir \"C:\Program Files\FileZilla Server\""

  Quotes and spaces must be entered exactly like that.

• On Debian Linux, as root, open in an editor the file /etc/systemd/system/filezilla-server.service and edit the line following the [Service] label, like this:
  
ExecStart=/opt/filezilla-server/bin/filezilla-server --config-dir

  Where is the directory where you want to relocate
  the configuration files.

  Then restart the service, with the following command:
  
sudo systemctl restart filezilla-server
