What is a .SDZ file?

The file extension .SDZ is associated with a Spring Content Package. This type of file is specifically used by video games that are created using the Spring game engine, which is designed for real-time strategy (RTS) games. The .SDZ file contains various game-related data such as maps, graphics, and scripts for computer-controlled players, which are often written in the LUA programming language. These files are essentially ZIP files that are compressed to save space, but they are given the .SDZ extension to indicate their specific use with the Spring engine.

To open or work with .SDZ files, you can use several programs: 1. **Spring**: This is the primary software that uses .SDZ files since it is the game engine for which these files are designed. 2. **Corel WinZip**: A popular file compression and decompression tool that can handle .SDZ files as they are in ZIP format. 3. **7-Zip**: Another widely used free software that can open many types of compressed files, including .SDZ files. 4. **Apple Archive Utility**: If you are using a Mac, this built-in utility can manage .SDZ files, allowing you to decompress them and access their contents.

These tools help you either run the game content as intended in the case of the Spring engine or allow you to view and modify the contents of the .SDZ files if you are developing or modifying a game.
