GrandPerspective

The tiny open-source treemap that shows your biggest files instantly.

+ GrandPerspective: 強み

  • Free and open source with a tiny footprint
  • Treemap rectangles make the single biggest space hog obvious
  • Fast rescans and a loyal power-user community

- GrandPerspective: 弱み

  • Treemap UI is utilitarian — no sunburst, no guided cleanup
  • No collector tray or duplicate finder; deletion is file-by-file
  • Development pace is slow compared with commercial rivals
