Overview

Shared game content loaded by every GameServer instance

Shared game content. One copy exists per installation at the release root (Data/). Every GameServer process reads from this folder in addition to its own per-server Data/ identity folder.

Shared vs Per-Server

Root	Scope	Contents
Data/ at release root (this section)	One per installation	Items, monsters, events, skills, shops, plugins, quests, messages, maps
GameServer/Data/	One per GameServer instance	Per-server identity .dat files, documented under the GameServer section

Running multiple GameServers on one machine means multiple GameServer/Data/ folders (each with a unique ServerCode and LicenseKey) but a single shared Data/ folder that every instance reads.

Sections

Root files

File	Purpose
Command.xml	NPC-triggered chat commands and dialogs

MapManager.xml	Per-map properties, PK zones, restrictions
MapServerInfo.xml	Multi-server map ownership
Message.xml	System message strings
ShopManager.xml	NPC-to-shop mapping

Overlays

A GameServer can layer a second folder on top of the shared Data/ folder to override specific files without editing the shared copy. See Data Overlays.

Game Data Sync

Many files here are pushed from the server to the client at login (skills, item definitions, custom visuals, chaos mix recipes, and more). Edits to those files take effect after the next relog per player, not instantly. See Game Data Sync for the full list and effect-timing rules.

Reload vs Restart

• Restart required for nearly every file under Data/. Loaders run once at GameServer startup.

• Hot reload supported by a few plugins (ResetSystem, SkillSpeedScale, ChaosMix, CustomCombo, CustomStartItem, MuHelperPickup, and a few others). Each plugin page documents its own reload trigger.

• Synced files also require each player's next login to see the new data, even after GameServer restart - see Game Data Sync.

When in doubt, restart.

Where to Start

New admins usually want these first:

1. Item/ - item database, drops, options

2. Monster/ - stats and spawns

3. Shop System - NPC shop contents

4. Plugins/ - feature toggles

5. Specific Event/ pages for the events you run
