Using the Review Files Section
Below the recommendations, you will find tabs for Applications, Documents, and other categories. The Documents tab is particularly useful because it has sub-tabs for Large Files, Downloads, and File Browser. Large Files shows your biggest files sorted by size, making it easy to spot space wasters.

Save this folder to your sidebar for quick access during monthly cleanups. This gives you an always-updated view of your biggest, oldest files.

While Apple's built-in tools are good, third-party apps offer more detail and automation. Free options scan your entire disk and show visual breakdowns of space usage. They can find hidden files, application leftovers, and system junk that the built-in tool misses.

Some also monitor your disk in real-time and alert you when space gets low.
