Which of the following is an example of a compound file that EnCase can mount?

A compound file is a file format that can contain multiple pieces of data or streams within a single file structure. This concept is crucial in digital forensics, as it allows for the organization and efficient handling of data that might otherwise be spread across several files.

The catalog of examples provided in the question includes registry files, email files, and compressed files, all of which can encapsulate multiple data streams or elements. Registry files, for instance, consist of a variety of configuration settings stored in a structured manner, making them a compound file since they aggregate different segments of data regarding system configurations.
