A user can manually add new file headers and extensions by doing which of the following?

The correct answer lies in the process of using the File Types view within the EnCase forensic software. When working in EnCase, the File Types view allows users to manage and customize file signatures effectively. By right-clicking in this view and selecting "New," users can add new file headers and extensions directly into the specified categories. This process is straightforward and ensures that new file signatures are integrated seamlessly into the system, allowing for accurate forensic analysis of various file types that may not be recognized by default.

This method is particularly advantageous as it allows examiners to curtail any limitations they encounter with existing file signatures. It provides a user-friendly interface for updating and customizing the file signatures that EnCase uses to identify different file types on a disk.

The other options may involve steps related to file signature management but do not accurately describe the most effective method for manually adding new file headers and extensions in the context of EnCase. For example, manually inputting data into the FileSignatures.ini file involves more complex editing that could lead to errors. Right-clicking a file to choose "Add File Signature" might mislead to more general actions not focused on the customization of signatures. Similarly, creating a hash set is a different function entirely and does not directly contribute
