question about map_msg.conf

[Valcars]

Hi everyone I wanted to ask for information since this conf folder is new to me ... I was wondering if it was possible to create another file.con inside the msg_conf folder and call it for example (map_msg _ ???. Conf) obviously the language instead of the "?".
without modifying the existing ones, and if it was possible in game to choose which language to use .....! I hope I explained myself well .... and I'm waiting for your answers xD

I don't remember any action to choose which files to read.

When you want to use any of that translated just renamed it.

ah ok so obviously the choice of language is also to be excluded ......... well I joked xD thanks for the explanation
