DiskBuddy

DiskBuddy is a disk space analyzer for macOS and Windows that scans a drive and maps every byte it finds. Instead of digging through Finder folder by folder, you get a picture of where the space went. The site says a 118 GB home folder holding roughly two million files finishes scanning in about ten seconds.

What stands out in this DiskBuddy review is the eight ways to read one scan: folders, sunburst, flame, bubbles, mind map, top sizes, age map and treemap. It also matches duplicates byte for byte, lists apps with the caches and logs they scattered, and keeps snapshots to compare. Good fit for developers, designers and anyone on a small SSD.

Verdict: a solid productivity utility if you would rather see your drive than guess at it. Nothing is removed in the background, since items go to a staged cleanup list you review first, and scanning stays on your machine with no account to make. It is a one time purchase, and the same key covers both Mac and Windows.
