File Copier Mod

A modern continuation of the Copy-Paste / Copied mods for automatic world data syncing.

Overview

A Minecraft mod for Fabric and NeoForge that copies files from config/copy/ into newly created worlds.

Features

• Automatic File Copying: Copies any files from config/copy/ into new worlds
• Datapack Injection: Datapacks in config/copy/datapacks/ are loaded before world generation, allowing terrain-modifying datapacks to affect the spawn area
• Hash-based Updates: Only copies files when they've changed (uses MD5 hashing)
• Configurable: Option to copy to existing worlds or only new ones

Folder Structure

config/
├── copy/
│   ├── datapacks/           <- Datapacks loaded BEFORE world generation
│   │   ├── my_datapack/     <- Affects terrain generation at spawn!
│   │   │   ├── pack.mcmeta
│   │   │   └── data/
│   │   └── another.zip      <- Zip files supported
│   │
│   └── (other files)        <- Copied into world folder after creation
│
└── file_copier.properties   <- Configuration file

How It Works

Terrain-Modifying Datapacks

Datapacks placed in config/copy/datapacks/ are injected into Minecraft's pack repository system via Mixin before world generation begins. This means:

• Custom biomes will generate at spawn
• Custom structures will appear in the initial terrain
• Worldgen features work from the very first chunks

Other Files

Files placed directly in config/copy/ (not in the datapacks subfolder) are copied into the world folder after world creation, using the same relative path structure. This is fantastic for modpack devs who want to include customnpc data or schematics that will automagicaly copy into any world the user / server creates.

Configuration

Edit config/file_copier.properties:

# Set to false to only copy files into new worlds
copyExisting=true

And to the entire modding community for modern tooling support.

This project exists to keep the utility alive for current modpack creators. ❤️
