How to Export and Upload Server Packages for Your ATS Server
Export server_packages.sii and server_packages.dat from your American Truck Simulator client and upload them to your dedicated server for DLC and mod support.
American Truck Simulator dedicated servers require server packages files to load map data, DLC content, and mods. These files are exported from your game client and uploaded to the server. You must re-export them whenever you add or remove DLC or mods.
Export Server Packages
Enable the developer console
On your PC, open your ATS config.cfg file (usually at Documents/American Truck Simulator/config.cfg). Set:
uset g_developer "1"
uset g_console "1"Save and launch ATS.
Export the packages
In the ATS main menu, press ~ (tilde) to open the console. Type:
export_server_packagesThis generates two files in your ATS Documents folder:
server_packages.siiserver_packages.dat
Upload to the server
In the XGamingServer Panel, stop the server. Click Files in the sidebar and upload both files to the server root directory, replacing any existing ones.
Start the server
Start from Console. The server loads your DLC maps and mods.
When to Re-Export
You need to re-export and re-upload server packages whenever:
- You buy or activate a new DLC (map pack)
- You add or remove mods from your client
- You update the game version (major updates may change package format)
Without matching server packages, players may see missing roads, invisible terrain, or connection errors.
