Every disk tool on Windows hands you a folder tree and wishes you luck. DiskScope attributes every byte to the application that owns it — program files, user data, cache, logs, and the leftovers of software you uninstalled two years ago.
The drive on the right is real data from a real machine. Run the scan and watch 1.82 TB stop being folders and start being answers.
Nothing here phones home. The demo is client-side; so is the app.
Chrome isn't C:\Program Files\Google\Chrome. It's that, plus 34 GB of profile in AppData, plus a GPU cache, plus Crashpad dumps, plus a registry hive, plus a scheduled task. DiskScope correlates registry entries, package managers, digital signatures, services and known-path signatures into one profile — and scores how sure it is.
Vendor folders, caches and configs still on disk — but no executable, no registry key, no package entry. Adobe uninstalled in 2023 and left 12.4 GB behind. Nine signals say gone; the bytes say otherwise. That's an orphan, at 99% confidence.
Every item carries its score and the signals behind it. Low confidence never gets a green "safe to delete" badge — it gets Review, and you get the reasoning.
No separate "duplicate finder", no second tool for big files. One index of the filesystem, kept in SQLite, queried nine different ways — so the second scan takes seconds, not minutes.
DiskScope never issues a delete. Items go to the Recycle Bin, the plan is written down first, and undo restores every path it touched. Catastrophic paths are refused in the Rust backend — not hidden in the UI, refused at the source.
C:\Windows\System32 and an active WSL disk image are on the guarded-path list. No override exists, by design.The index lives in a SQLite file on your machine. Nothing is uploaded. There is no server to upload it to.
Tauri 2 + a multi-threaded Rust filesystem walker. Full scan of a 2 TB SSD in minutes; incremental rescans in seconds.
Every cleanup writes a manifest of what moved where. One click puts all of it back, exactly where it was.
DiskScope is being built in the open for Windows 10 and 11. Star the repo to get the first release — or scroll back up and keep poking at the treemap, it doesn't mind.
