Hi CvS
Don’t worry about the specific contents of the TFAR folder as they folder structure has changed quite a bit over time. A3S creates an exact copy of the mod folders for each player, so provided A3S synced completely, the mod folder should be fine.
The only real trick to getting TFAR up and running is copying the Teamspeak Plugins.
So first things first, make sure you’ve installed the latest version of Teamspeak 3.
You will copy the contents of the /@task_force_radio/teamspeak/ folder to the Teamspeak 3 Plugins folder. e.g. C:\Program Files\Teamspeak 3\Plugins.
Once that is done, launch Teamspeak and Enable the TFAR plugin by clickng Settings->Plugins in the toolbar and ticking the Task Force Arrowhead Radio Arma 3 Plugin.
If you’ve done all of this, and you still don’t come right let me know and we can help you on our ZA Teamspeak Server.
