## What it is
LightC is a free, lightweight Windows desktop utility for safe junk cleanup, disk space analysis, and system maintenance, built with React, TypeScript, Rust, and Tauri. It offers modules for cleaning temporary files, finding large files, removing app caches, cleaning the registry, and analyzing disk growth.

## Use cases
- free up space on my c drive
- find large files taking up disk space
- clean temporary and cache files on windows
- remove leftover files from uninstalled programs
- clean orphaned registry entries safely
- analyze which folders are growing on my disk
- clear wechat and qq desktop app caches
- clean up ai model storage like loras and embeddings

## When to choose
- you want a free, minimalist alternative to CCleaner-style cleanup tools on Windows
- you need safe, transparent cleanup with explicit safety warnings and backup/restore workflows
- you want to analyze disk usage and track what changed over time with snapshots
- you need to clean caches from Chinese social apps like WeChat, QQ, DingTalk, or Lark

## When to avoid
- you are on macOS or Linux, as it is Windows 10+ only
- you need automated scheduled cleanup without manual review
- you require enterprise fleet-wide disk management or remote administration
