macOS tells you how much is used by broad category. DiskSpace draws the whole disk as an interactive size map, so a forgotten 40 GB folder is visible at a glance rather than inferred.
No. It finds and shows - large files, duplicates, and what is inside them via Quick Look preview - and you decide. Nothing is removed without an explicit action.
Yes. Drive and filesystem coverage extends beyond the startup disk, which matters because that is often where the untracked bulk lives.
DiskSpace is a macOS-only app, built to stay light while a full-disk scan runs in the background.
