DiskletX

See where your disk space really goes. Treemap any drive, folder, or SSD, in a UI that doesn't look like 2010.

What it does

DiskletX scans any drive, folder, or SSD you point it at and renders the contents as a treemap - each block sized proportionally to what it takes on disk. You see instantly which folder is 60GB, which file is 8GB, and where all the "hidden" gigabytes actually live.

Why I built it

Windows tells you the disk is full without telling you what actually takes it. Existing tools looked like they froze in 2010 - grey menus, tiny fonts, sluggish scans. So I built one that looks like 2026 and runs like it too.

How it works

Real-time treemap. Rescan on drag, no waiting on full re-index.
Drag-and-drop navigation. Zoom into any block, back out with one click.
WinUI 3 native. Dark mode by default, respects Windows theme.
