Windows C Drive Cleaner

Problem

Windows C drive capacity is often consumed by caches, logs, WeChat/QQ/browser data, and large application folders. Manually hunting for removable files risks deleting needed data, while deleting system directories can break installed apps. This skill targets an ops workflow: inspect removable items first, then free space safely.

How It Works

The skill runs scanning, analysis, and report generation locally, without reading or uploading user files. It produces a tiered report and a local interactive service. A typical flow is: run run.py to scan, classify, and generate an HTML report; show the report in the sidebar; let the user trigger unlock, one-click cleanup, or migration; then execute actions such as clean_green or migrate_items after explicit confirmation.

Cleanup is constrained by safety tiers. Green-zone items are mainly auto-rebuildable caches, so removal risk is lower. Red-zone items include system core components and installed application bodies; they are not displayed in the report and are not placed in the deletion whitelist. Migration moves large folders such as WeChat, QQ, or games to another drive and keeps the app usable through a directory junction.

Boundaries

The skill targets Windows 10/11 and requires Python 3.10+; administrator privileges improve access to system caches. Cleanup and migration are high-impact operations, so items must be listed and explicitly confirmed by the user. If cleanup or migration returns a permission limit before authorization, treat it as normal gating, not a failure.
