What is the primary function of Disk Utility on a Mac?

The primary function of Disk Utility on a Mac is related to managing disk drives and volumes rather than directly removing unnecessary files. While Disk Utility has various capabilities including formatting disks, verifying and repairing file system errors, and managing disk partitions, its primary focus is not on improving system performance by removing files.

Disk Utility enables users to check the status of their disks, repair disk permissions, and perform tasks that are critical for maintaining the integrity of file systems. It provides tools for creating, deleting, and managing disk images as well as for restoring volumes. Understanding its comprehensive role helps users maintain the health of their storage infrastructure, which indirectly can lead to better system performance.

Performing data management tasks such as cleaning up unnecessary files in the operating system is typically handled by other tools or third-party applications specifically designed for that purpose. Therefore, while option C may imply an aspect of improving performance, it does not accurately reflect the primary functions of Disk Utility.
