GrandPerspective
The tiny open-source treemap that shows your biggest files instantly.
＋ GrandPerspective: จุดแข็ง
- 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: จุดอ่อน
- 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
