What is a Minecraft DAT File?

DAT files are Minecraft save files used to store important game data such as player inventories, world settings, advancements, achievements, chunk information, and other internal game structures.

Common Minecraft DAT files include level.dat, which stores world metadata and seed information, and player.dat, which stores player inventory, health, XP, coordinates, abilities, and progression data.

Minecraft DAT files are internally built using the NBT (Named Binary Tag) structure format. Mcgic DAT Editor lets you inspect and modify these files visually without needing to install desktop applications or complicated editors.
