The nine views

What each view is for, and how they stay in step with one another.

One scan, nine readings

Every view reads the same scan and shares the same root, selection and filter. Choose a folder in the treemap and it is still chosen in the sunburst, the outline and the map.

  • Treemap — area is size, nesting is folders
  • Folders — one level at a time, as cards
  • Sunburst — rings go deeper as they go out
  • Flame — each row is one level deeper
  • Bubbles — folders packed inside their parents
  • Mind Map — your largest folders, radially
  • Top Sizes — the heaviest files or folders, anywhere
  • Age Map — when your bytes were last touched
  • Outline — every folder as an expandable list

Moving around

Double-click or press Return to drill into a folder; ⌘[ goes back and ⌘↑ goes up. The bracket keys change how deep the drawing goes. Number keys 1–9 switch views, and ⌘1–⌘7 switch sections.

Colour

Colour carries meaning rather than decoration: by kind of file, by folder, or by age. The legend says which is in use, and the same palette is used in every view so a colour means the same thing throughout.
