# UTTypeBundle

A base type that represents a directory that conforms to one of the bundle layouts.

```
extern UTType * const UTTypeBundle;
```

## Discussion

Bundles differ from packages in that a bundle has an internal file hierarchy that <doc://com.apple.documentation/documentation/CoreFoundation/CFBundle> can read, while packages display to the user as if they were regular files. A single file system object can be both a package and a bundle.

The identifier for this type is `com.apple.bundle`.

This type conforms to [`UTTypeDirectory`](/documentation/UniformTypeIdentifiers/UTTypeDirectory).
