What is a WORLD file

WORLD files mostly belong to The Sims 3 by Electronic Arts. A WORLD file contains a virtual world used in video games such as The Sims 3 and Terraria. The WORLD file used in The Sims 3 contains roads, terrains, Sims, and buildings in a 3D world created with The Sims 3 Create a World Tool. Apart from worlds, Terraria also uses game maps saved in WORLD files. WorldPainter, a program for generating Minecraft worlds saves a world in a file with WORLD filename extension. Such files are exported to MCA format before they are used in Minecraft. Gazebo robotics simulation software saves a robot simulation model in a WORLD file.

How can I open a WORLD file?

You need a suitable software like The Sims 3 to open a WORLD file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your WORLD file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a WORLD file directly in the browser:.

WORLD file format:

To view or edit WORLD files you need to know the file format, because it determines how the data in this file is stored. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So you need a detailed analysis of a file to find out the format and the associated program. Our examination of the WORLD files comes to the following conclusion:

WORLD is seldom used as a file extension and includes different formats for different programs. However, the following two file formats are common:

35% of all WORLD files are using the well-known JSON file format to store the data. JSON (JavaScript Object Notation) is a lightweight data−interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. These files contain text and words, not binary data. Most of these files are 3 KB to 1 MB in size. It is a modern file type. The keywords objects, float, valuetype, ambient, oceanlevel, respawn, weather and group are typical for these files. These files can be linked to house and beach.
15% of all WORLD files are based on the popular GZIP file format. Gzip is a compressed archive file format. Gzip (GNU zip) is only capable of compressing a single file. They consist of illegible, cryptic characters. Most of these files are 1 MB to 47 MB in size.

All the rest of the WORLD files (50%) have different formats, the following 5 formats can be found: XML, DBPF and sdf. These files are often connected to island, game, save or town. Drag & drop your file here to see the file format and a preview of your WORLD file!
