eating your disk.
Quarry is a fast, native disk-usage explorer written in Rust. Scan a drive in seconds, then find the big stuff two ways — a sortable size tree-table and a cushion-shaded treemap.

QuarryFind the big stuff. Fast.
A clear picture of your disk in one quick, native window — no installer, no bloat, no telemetry.
Treemap
A squarified, cushion-shaded map colored by file type. Every box is a folder or file, sized by what it uses — the biggest space hogs jump right out. Click to drill in.
Size tree-table
Folders and files sorted largest-first, expandable, with usage bars and item counts. Virtualised, so it stays snappy even with hundreds of thousands of files.
Parallel scan
Walks the filesystem across every CPU core at once, on a background thread with live progress. The window never freezes, even mid-scan of a full drive.
Drive picker
Scan any detected drive, a folder you pick, or drop a folder on the exe. Jump back up with a clickable breadcrumb.
Reclaim space
Delete a folder or file straight to the Recycle Bin — right-click or the Delete key, with a confirm. Recoverable, never a hard delete.
Native & light
One ~11 MB Rust binary. No runtime to install, nothing phoning home. Reveal anything in Explorer with a click.
Built for big drives
A 2 TB drive has millions of files. Quarry walks them in parallel across all your cores and builds a flat in-memory tree, so the scan finishes while other tools are still warming up — and the UI only ever draws the rows on screen.
Scan in parallel
Every subdirectory is walked on its own core (rayon), summing sizes bottom-up.
See it two ways
Flip between the size tree-table and the treemap — same data, whichever reads faster for you.
Reclaim
Drill to the culprit, reveal it in Explorer, or send it to the Recycle Bin and watch the totals update.
// every subdirectory, scanned in parallel let children = subdirs .into_par_iter() // all cores .map(|dir| scan(dir)) // recurse .collect::<Vec<_>>(); let total = own_size + children.iter().map(|c| c.size).sum::<u64>();
