Features

• Junk Cleaner — Quick and deep scans for temporary files, Delivery Optimization files, thumbnails, DirectX shader caches, and selected rebuildable Microsoft Defender caches.
• Large Files — Find space-consuming files with drive-aware scanning, risk indicators, selection controls, and safe deletion feedback.
• Social App Cache — Review cache categories from WeChat, QQ, DingTalk, Lark, and other supported desktop apps before cleanup.
• System Slim — Review optional Windows system components and space-saving settings with clear safety warnings before applying changes, including rebuilding the Windows Search index when Windows.db grows abnormally large.
• Old Drivers — Identify unused third-party driver packages while protecting drivers currently in use; supports backup and restore workflows.
• Uninstall Leftovers — Detect probable remnants of removed applications across common locations using confidence-based results.
• Registry Cleanup — Find orphaned registry references and provide backup-aware cleanup with operation feedback.
• Context Menu Cleaner — Review invalid context-menu entries and remove unwanted shell integrations.
• Directory Analyzer — Inspect directory space usage, drill into large folders, and clean supported temporary caches.
• Disk Growth Analysis — Compare disk snapshots to locate changed files and directories over time.
• Shell Icons — Manage third-party This PC shell icons with registry/ACL backup, restore, and anti-respawn protection.
• AI Model Storage — Analyze local model, LoRA, embedding, and related cache storage, then remove selected model data.
• Localization — Switch between Simplified Chinese, Traditional Chinese, English, and Japanese; module pages, scan stages, settings, and stable backend labels follow the selected language.

Requirements

• Windows 10 or later.
• Node.js 20.19+ and npm.
• Rust toolchain and the Tauri 2 prerequisites.

Development

npm install
npm run dev
npm run build
npm run tauri dev

Portable Mode

Place LightC.portable.json beside the executable. LightC then stores its configuration, local data, and WebView data beside the executable instead of the default user profile location.

Safety Notes

• LightC does not scan or delete the Windows Defender root, quarantine, definition updates, platform data, or other protected Defender data.
• Defender cleanup is limited to the rebuildable LocalCopy and Support directories.
• System32 cleanup is limited to the explicitly supported DirectX shader cache path.
• Some files require administrator permission or a system reboot and may remain listed as incomplete.
