C-Drive Manager is a lightweight Windows disk-and-memory maintenance tool built with Rust + Tauri; its installer is only 2.4MB. It achieves second-level space analysis by reading the NTFS MFT directly, and offers four core functions: disk inspection, one-click cleanup, deep system cleanup, and startup management. It runs fully locally, makes zero network requests, doesn't scare users, and explains the principle and impact of every action. Open source and free, it's for every Windows user who wants to safely clean up C-drive space.
