Hi,
Third-party code is typically found in the lib/ext and platform/ext folders.
You can use west ncs-sbom to generate a report of all licenses in your build. Please refer to Software Bill of Materials

could you tell me which folders in the SDK contain third-party libraries? I need to remove some libraries with less permissive open-source licenses to meet compliance requirements. For example, licenses like Zephyr's Apache 2.0 are more friendly as they don't force mandatory code disclosure.

Hi, there's no automatic unused file/folder detection or copying tool in the SDK or VS Code extension.

You can refer to Adding your own code and nrfconnect/ncs-example-application: NCS example application, based on https://github.com/zephyrproject-rtos/example-application to better manage your codebase

You can create a "freestanding" application, where your code is outside the SDK tree and only references the SDK as a dependency. This keeps your repository small and focused

You can run something like "west build -p always -b nrf54l15dk/nrf54l15/cpuapp -- -DCMAKE_EXPORT_COMPILE_COMMANDS=ON" to get a list of everything that compiled in "compile_commands.json" (in your build folder)

Note: Don’t delete anything inside NCS/Zephyr. Only trim your application.
The SDK is a collection of git modules that west/CMake expects. Deleting inside NCS/Zephyr will break builds and updates.
