Every byte, drawn to scale.
Quarry maps your whole disk in seconds, then tells you what grew since the last time you looked.
Find the big stuff. Fast.
Two views of the same scan, and a straight answer to the question every other disk tool leaves open.
The Changes view
Quarry records a small size snapshot after every scan. Scan the same drive again and it shows you exactly what grew and what shrank in between, ranked by how much space moved. This is the answer to "my drive filled up and I have no idea why". C:\Users\you\AppData\Local\Temp+18.4 GB C:\Games\Starfieldnew 12.1 GB C:\Windows\Installer-6.2 GB
A treemap you can read
Squarified and cushion-shaded, so a folder's size is genuinely its area. Known file types share a legend color and every other extension gets its own stable hue, so the map never collapses into one grey mass. Hover for detail, click to drill in, one key to go back up.
Measured against the drive
The root row is compared to the volume's actual capacity rather than to itself, so the bar means something instead of always reading full. Free space sits in the status line beside it.
Parallel scan
The recursive walk is spread across every core with rayon, junction and symlink safe, running on a background thread with live progress so the window never freezes while it works.
Recoverable by default
Deleting from the tree or straight off the treemap goes to the Recycle Bin behind a confirm dialog. There is no hard delete anywhere in Quarry, so a wrong click is always undoable.
Reclaim space, safely
Finding the problem is half the job. Quarry also clears it, and it is honest about which parts are safe.
Smart suggestions
Temp files, thumbnail and browser caches, npm, pip, cargo and NuGet caches, crash dumps and the Recycle Bin. Each one is sized, ranked, and tagged either Safe or Review, so you always know what you are agreeing to before anything moves.
Orphaned patch cleaner
Windows caches installer patches in C:\Windows\Installer and never cleans them up. Quarry asks the Windows Installer API which of those .msi and .msp files no installed program still references, then clears only those. On a machine running for years this is routinely the single biggest win on the drive, and it is the one thing generic cleaners will not touch.
How it knows what changed
No service, no watcher, no database. Just a small file written after each scan.
Scan every core at once
The recursive walk is parallelised with rayon, so a full drive is measured in the time one thread would need for a fraction of it. Junctions and symlinks are followed safely, never in circles.
Write down what it found
Afterwards Quarry stores one line per directory over a megabyte and per file over fifty. That is a few kilobytes of plain text per drive, kept in your local app data. Nothing leaves the machine.
Compare on the next scan
Scan the same drive again and the new sizes are diffed against that snapshot. Anything that appeared, vanished, grew or shrank is ranked by the number of bytes that moved.
Act on the difference
The Changes tab shows the ranked list with the net space gained or lost. Click any row to open it in Explorer, or send it to the Recycle Bin without leaving Quarry.
Three tools, one idea
Small native Windows utilities that measure something precisely and then act on it. Same build, same look, no installers.
Watches how responsive the active app is and throttles whatever is starving it of CPU.

Quarry
Maps the whole drive as a treemap and tells you what grew since the last scan.
You are hereInstant file search straight off the NTFS index, and a content: query that searches inside your files.
sift.aimbetween.gamesGet Quarry for Windows
One executable. Run it and it works. Uninstalling is deleting the file.
Quarry is unsigned, so SmartScreen may warn on first launch: choose More info, then Run anyway. Scanning your own files needs nothing special. Clearing cached installer patches in Windows\Installer needs Administrator, and Quarry asks for it only at that moment.
