The problem is not finding files. It is knowing what to trust.

When a Windows drive fills up, one tool shows a maze of folders and another asks you to delete blindly. Purify gives you a calmer path: understand the space, review the reason, then clean with a way back.

How it works

01 · Understand	02 · Decide	03 · Undo
Scan a drive and see the largest consumers at a glance.	Get explainable suggestions with a confidence level: Safe, Likely safe, or Review needed.	Approved items move to a local quarantine. Restore them whenever you want; permanent purge is explicit.

What you get

🗺️ Disk Map · A fast treemap of the space that matters, using a direct NTFS/MFT reader when elevated and a portable parallel walker otherwise.

🛡️ Safe Cleanup · 30+ built-in signatures for caches, leftovers and developer clutter, each with a plain-language reason.

↩️ Quarantine · Cleanup is reversible by default. There is no silent delete and no “are you sure?” theatre after the fact.

🗂️ Organizer · Preview and sort loose files in Downloads with one-command undo.

🚦 Disk Guardian · See storage pressure before it becomes an emergency.

🔒 Private by design · Offline, no telemetry, no registry edits, and no network dependency in the core product.

Why Purify?

	Traditional folder viewers	One-click cleaners	Purify
Understand where space goes	Partial	Rarely	Disk map + largest consumers
Explain what can be removed	No	Sometimes	Reason + confidence on every suggestion
Recover after cleanup	Manual	Usually no	Local quarantine + restore
Work offline	Yes	Varies	Yes, by design
Built for developers	No	No	CLI, rules in TOML, Rust workspace

Start in 60 seconds

1. Download the latest Windows release.
2. Open Purify and choose a drive or folder.
3. Press Scan to understand the space, then Analyze for suggestions.
4. Review the reason and confidence. Press Clean to move approved items to quarantine.

Nothing is deleted by default. You stay in control at every step.

Scriptable mode

The CLI is useful for read-only checks, automation and CI diagnostics:

purify scan C:\ --top 20
purify analyze C:\Users\me
purify clean C:\Users\me                 # preview only
purify clean C:\Users\me --apply         # reversible quarantine
purify restore <id>

Built for speed, designed for restraint

With administrator rights, Purify reads the NTFS Master File Table directly instead of walking every file. Without admin it uses a parallel walker. Matching is compiled once, paths are normalized once, and directory sizes are computed only when needed.

On a representative 7,400-file profile, release builds measured roughly 20 ms for scan and 28 ms for analyze. Results depend on the drive and hardware; the benchmark method lives in ARCHITECTURE.md.

A small workspace with clear boundaries

Area	Responsibility
purify-core	Rules, suggestions, quarantine, organizer and guardian; safe Rust only
purify-ntfs	The only crate with raw volume/MFT access
purify-cli	Scriptable command-line interface
purify-desktop	Tauri 2 desktop experience
knowledge-base/	Community-editable cleanup signatures

git clone https://github.com/Mahdi-mortazavi/purify.git
cd purify
cargo test --workspace
cargo fmt --all --check
cargo clippy --workspace --all-targets -- -D warnings

CI runs formatting, Clippy, unit and integration tests, desktop builds on Windows and Ubuntu, and dependency-policy checks on every pull request.

Contribute to the trust layer

You do not need to be a Rust expert to make Purify better. A cleanup signature in knowledge-base/ is a valuable contribution when it clearly states what it targets, why it is safe, and how it is tested.

1. Read CONTRIBUTING.md and ARCHITECTURE.md.
2. Pick an issue labelled good first issue or propose a focused improvement.
3. Keep the safety boundary explicit and include a reproducible test when behaviour changes.

Bug reports and UX feedback are welcome in Issues. Please include your Windows version, whether the app was elevated, the command or screen involved, and a safe reproduction path.
