How to change Filetransfer port to another port?

As the title says how do I change the port of the Teamspeak Server Filetransfer.My server system is Window Server 2019

  • Stop the server instance.

From now on start it with parameter filetransfer_port=123456 or put the parameter into an ini file.

To create the ini file start the server with parameter createinifile=1 and you will fine a ts3server.ini in server folder.
There you can change settings and start server with parameter inifile=ts3server.ini

  • Start the server instance with one of the parameters.

Oh, it worked, thanks!
