Why Server Package Files Must Be Generated

They Reflect Your DLC and Mod Setup

Each player’s ATS installation can have a unique mix of:

• Official DLCs (map expansions, cargo packs, tuning packs, etc.)

• Steam Workshop mods or custom mods

• Load order differences

The server package files capture this exact combination. They tell the dedicated server what content to expect so that clients must match. Because every setup is different, there’s no universal package to download.

To extract your files for the server follow the below steps.

Enable the in-game console:

• Navigate to Documents/American Truck Simulator/config.cfg

• Change:

  • uset g_developer "0" → "1"
  • uset g_console "0" → "1"
    
    
• Save the file and restart the game

Export the server packages:

• Launch ATS, open the console (press ~, ` or \ depending on layout), and enter:

  • export_server_packages

• This creates:

  • server_packages.dat

  • server_packages.sii

• Both will appear in your Documents/American Truck Simulator/ folder

Deploy them to your dedicated server:

• Copy these two files into your server's home directory (e.g., where server_config.sii is located)

• With them in place, your server can properly recognize the DLC and mod configuration and launch.
