grove
see exactly where your gigabytes went.
your mac's storage is a mystery until it isn't. a 'disk almost full' alert appears, you open about this mac, and all you see is a coloured bar with no detail. grove fixes that: it scans your whole disk and renders a treemap where every rectangle is a folder or file, its area proportional to how much space it takes up.
click any rectangle to zoom into that folder. keep drilling until you find the culprit — the 4k footage you forgot to move, the three copies of node_modules, the 12 gb docker image you pulled once. then hit reveal in finder and deal with it. grove never touches your files; it only shows you where they live.
how it works
- 01
scan
open grove and click scan. it reads your disk directly and builds the treemap — usually under 30 seconds for a 512 gb ssd.
- 02
explore
the treemap renders immediately. the biggest rectangles are your biggest space consumers. hover to see names and sizes; click any folder to drill in.
- 03
find it
navigate the breadcrumb back up to widen the view, or keep drilling down. when you find the file, hit reveal in finder.
