What is a .NSZ file?

An NSZ file is a type of compressed file specifically used for Nintendo Switch games. It is essentially a smaller, compressed version of an NSP file. NSP files are the standard format for Nintendo Switch game packages and contain all the data needed for a game, such as the game's program, content, and other necessary files. By compressing this data into an NSZ file, the file size is reduced, making it easier and faster to download and store.

To use NSZ files, you need a Nintendo Switch that runs custom firmware, which is a modified version of the official Nintendo firmware. This allows the console to recognize and install games from NSZ files, which is not supported on consoles with only the official firmware. Additionally, NSZ files can be used with certain emulators, which are programs that mimic the Nintendo Switch hardware on other devices like computers, enabling you to play Nintendo Switch games without the actual console.

To open or manage NSZ files, you can use several specific tools and programs: 1. **nsz**: This is a popular tool that can be used to compress and decompress NSZ files. 2. **NSC_BUILDER**: This program helps in creating, editing, and managing NSZ files along with other types of Nintendo Switch game files. 3. **Switch Army Knife (SAK)**: This is a versatile tool for handling various file operations related to Nintendo Switch gaming files, including NSZ files.

These tools are essential for anyone looking to manage or modify their Nintendo Switch game files, especially when dealing with compressed formats like NSZ.
