What is the purpose of a file extension?

To identify and classify file types
To store information securely
To provide encryption for email
To act as a locking mechanism

The correct answer is: To identify and classify file types

File extensions are used to identify and classify file types. They are a way to indicate to a computer which program should be used to open a specific file, as different programs are designed to handle different types of files. Options B, C, and D are incorrect because they do not accurately explain the purpose of file extensions. File extensions do not store information securely, provide encryption for email, or act as a locking mechanism. They only serve to identify and classify file types.
