You can open WORLD files with WorldsShaper, which can be used to build worlds and save them as WORLD files for sharing with other users. You can also open them with WorldsPlayer a program similar to a web browser that allows you to explore the 3D virtual world saved in a WORLD file.

WORLD files must be distributed with their referenced resource files. If they are not, you may not be able to open the files or parts of the world will be missing.
