Wanna run server with server.cfg instead command lines because of language problems. Then searched inside folder server -> my server identity -> cfg and nothing. Used command server.writecfg and after 1s console printed Config Saved. Checked again folder and nothing. Tried server.readcfg and i think server loaded it but no file again in the directory. How to generate cfg file from my old server then use it.

The server.writecfg command does not save to server.cfg, it only saves your ownerid and moderatorid to users.cfg. You'd need to manually create/edit the server.cfg file.

Thanks Wulf, can you reffer me where can find example or do it. Also if make this config and put it inside folder, server will read it properly?

It's just one command per line, nothing fancy. server/your_server_identity/cfg/server.cfg
