Which utility would you use to check the size of installed disks and free space?

The correct utility to check the size of installed disks and free space is System Information. This tool provides a comprehensive overview of the system’s hardware and software, which includes details about the disks installed on the system. Specifically, it allows users to view the total capacity of each disk as well as the amount of space that is currently available.

System Information gathers data from various hardware components and summarizes it into an easily navigable interface. When looking for disk space information, users can find details on each volume, including the size, free space, and file system type, making it a suitable choice for monitoring disk status.

Other utilities listed have different functions. Task Manager focuses primarily on monitoring running processes and applications, and while it provides some basic disk usage statistics, it does not offer detailed information about disk capacity and free space. Resource Monitor provides a more granular view of resource usage, but it's oriented towards monitoring CPU, disk, network, and memory usage in real time rather than giving an overview of disk sizes. Performance Monitor is geared towards gathering performance data over time and may not directly show the current disk space statistics in the same way that System Information does.
