Free up space on your PC without fear.

Tell me when it's out

We'll email you once, when it's out. Nothing else.

It knows more than 140 kinds of folders

The same rules as the Mac version, plus Windows' own. Each one says which tool recreates it and how to clean it properly: if the tool has its own command, it uses that.

What Windows leaves behind

• Windows Update downloads and upgrade leftovers ($WINDOWS.~BT)
• Windows.old, the previous installation, for you to decide
• Temp files, Delivery Optimization cache and crash dumps
• Explorer thumbnails and DirectX shader cache

For developers

• npm, pnpm, Yarn, uv, pip, NuGet, Cargo, Go, Maven and Gradle caches
• Visual Studio, VS Code, Cursor and JetBrains caches
• Docker, WSL and Podman virtual disks, so you decide with real numbers
• Ollama, LM Studio and Hugging Face AI models

Your everyday apps

• Chrome, Edge, Teams, Spotify and Adobe caches
• Installers you already used in Downloads
• OneDrive files downloaded to your PC
• Old versions of apps that update themselves

What it leaves alone

WinSxS, the page file, the hibernation file and the Windows Installer cache look huge, but Windows needs them. DiskSpace AI explains what they are and why you shouldn't delete them by hand, instead of promising gigabytes that end up breaking something.

Just like on Mac

• A color map. Green recreates itself and comes selected; amber is for review; gray is your data and is only shown.
• With a safety net. Your files are kept 7 days and can be restored.
• Your files never leave your PC. No account, no analytics, no tracking.
• One-time payment, no subscription. Analyzing is free. The Windows license is separate from the Mac one; pricing at launch.
