Project Zomboid (Dedicated Server) stores its config files at %USERPROFILE%\Zomboid\Server on Windows. That folder holds the server rule set — multipliers, timers, slot counts and the admin list. Checkpoint64 already knows it, backs it up automatically and keeps every version, so a config that got reset is one click from restored.
