# CFBundlePackageType

The type of bundle.

## Discussion

This key consists of a four-letter code for the bundle type. For apps, the code is `APPL`, for frameworks, it’s `FMWK`, and for bundles, it’s `BNDL`. The default value is derived from the bundle extension or, if it can’t be derived, the default value is `BNDL`.
