LightC is a Windows desktop utility for safe junk cleanup, disk analysis, and system maintenance. It is built with React, TypeScript, Rust, and Tauri.

• Junk cleanup with quick and deep scan modes.
• Windows cleanup categories including temporary files, Delivery Optimization files, thumbnails, DirectX shader caches, and selected Microsoft Defender non-critical files.
• Large-file, disk-health, hotspot, and disk-growth analysis.
• Registry redundancy, shell/context-menu, uninstall-leftover, old-driver, and social-app cache tools.
• AI model storage analysis and portable mode.
• Safe deletion checks, detailed results, optional reboot deletion, and protected system paths.

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

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

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.

• 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.
• Review selected items before permanent cleanup and keep important data backed up.
