02 / Overview
What it is
DiskCleaner is a portable cleaner for the C: drive on Windows. One .exe, no installation: a dark window with checkboxes and sizes, a delete button with confirmation and a large-folder finder. It clears temporary files, caches from Windows, browsers and NVIDIA, logs, dev caches and the recycle bin.
Items marked as requiring admin have a restart-as-admin button in the window. Aggressive targets such as Windows.old, Prefetch and the Go module cache stay off by default, and files locked by the system are skipped and counted separately. The app updates itself: it checks SHA-256 and accepts only builds with a valid Authenticode signature pinned by thumbprint.
03 / How it works
How it works
Run the exe
Download DiskCleaner.exe from the releases, verify its SHA-256 and double-click it — nothing to install.
Pick categories
Checkboxes are grouped by theme — system, NVIDIA, logs, browsers, dev caches, AI caches, app caches — and show their size.
Scan and clean
A scan lists what can be freed per category, and deletion only happens after a confirmation that shows the total volume.
Restart as admin if needed
The Windows Update cache, CBS logs and WER reports need elevation — use the restart-as-admin button in the window.
