Read the full description
SpaceMap is a free, open-source disk usage analyzer for macOS. It draws a folder or the whole disk as one nested treemap: folders are frames, files are tiles colored by type. The map fills in while the scan is still running, so you don't have to wait for it to finish. Double-click to zoom into a folder, click a file type to dim everything else, right-click to reveal, rescan or trash. Sizes match du. Native SwiftUI, about 1 MB, no dependencies.
