A WORLD file contains information about a world in Starbound, a 2D space exploration game. It stores world information, such as the planetary location, universe coordinates, and any changes your character in Starbound has made to the world.

WORLD files contain all the modifications a Starbound character has made to the world. The more changes the character has made, the more information is stored and the larger the file size.

WORLD files can be found in the "universe" folder in the "Starbound" folder. For example, if you purchased Starbound through Steam, the WORLD files are stored in the following location in Windows:

C:/Program Files/Steam/SteamApps/common/Starbound/universe
