What is an NRO file?

NRO files mostly belong to Nintendo Switch OS. NRO files are Nintendo Switch executables that run on the Nintendo Switch operating system. They contain compiled binary code along with a custom header that tells the system how to load the app.
These files are built with tools such as devkitPro and libnx and are meant for use in homebrew or third‐party software. For instance, a supported launcher on a modded Nintendo Switch reads the header, loads the code into memory, and starts execution.
Key details summarized by FilExt.com include:

Designed specifically for Nintendo Switch hardware and firmware.

Not compatible with standard PC operating systems.

Often used in homebrew development and testing scenarios.

Require a special environment (modded Switch or emulator) to run properly.

FilExt.com tip: On a PC, if you open the file with a hex editor, you will see binary data and the unique header, but it cannot be executed.

How to open an NRO file
