A data pack changes how vanilla Minecraft behaves — new crafting recipes, loot, functions, advancements and mechanics — using the game’s built-in system. No mods or loaders needed.

How to install data packs for Minecraft Java Edition on PC
This guide is for Minecraft: Java Edition on PC. Playing on phone, tablet, console or Windows 10/11 Bedrock? See the Minecraft PE / Bedrock guides.

Follow these steps

1
Download a data pack
2
Create or pick a world

Data packs are installed per world. Either create a new world, or use an existing one. (You can add a data pack when creating a world via Data Packs on the create screen, or afterwards using Step 3.)

3
Open that world’s datapacks folder

Press Win + R, paste the path to your saves, then open your world → datapacks:

%appdata%\.minecraft\saves\<Your World>\datapacks
The datapacks folder inside your world folder — drop the data pack .zip here.
The datapacks folder inside your world folder — drop the data pack .zip here.

Replace <Your World> with your world’s folder name.

4
Drop the pack in & reload

Place the .zip into the datapacks folder. In-game, run /reload (or leave and re-enter the world). Confirm it’s active with /datapack list.

Some data packs need Experiments enabled — toggle them on the world-creation screen. A few also ship a matching resource pack for custom textures.

Fixing common problems

The data pack isn’t doing anything

Run /datapack list — if it’s not listed, the .zip is in the wrong folder or is for a different version. It must sit in that world’s datapacks folder, then /reload.

Do data packs work on servers?

Yes — put the .zip in <server>/world/datapacks and run /reload. On a realm, the owner adds it.

Data pack vs mod — what’s the difference?

Data packs use only vanilla features (recipes, loot, functions) and need no loader. Mods change the game code and need Forge/Fabric. Data packs are safer and multiplayer-friendly, but more limited.
