ferris-scan

The fast, multi threaded disk analyzer for Windows.

Are you tired of waiting 5 minutes for legacy tools to scan your NVMe drive? ferris-scan is a modern, lightweight system utility written in Rust. It utilizes parallel directory traversal to saturate your disk I/O, scanning massive drives in seconds.

Why buy this version? ferris-scan is 100% open-source (MIT License). You can always clone the GitHub repository and compile it from source for free.

Purchasing this pre-compiled Windows version gives you:

• Convenience: A ready-to-use .exe that works out of the box.
• Support: Your purchase directly funds my time to maintain the project, fix bugs, and develop the upcoming direct NTFS/MFT scanning engine.

Features:

• Parallel Scanning: Utilizes multi-threaded traversal (jwalk + rayon) to map massive NVMe drives in seconds.
• Dual Interfaces (GUI & TUI): Choose your workflow. Includes a modern, lightweight Graphical UI, plus a keyboard-driven Terminal UI for power users and headless servers.
• Treemap Visualization: Instantly spot space-hogs with dynamic, proportional treemaps (TreeSize-style) available in both interfaces.
• Zero Bloat: No Electron, no .NET, no web runtimes. Just purely native, memory-safe code in a tiny footprint (< 100MB RAM usage).
• Actionable Control: Interactively drill down into directories and delete files directly from the app.
• CSV Export: Export your structured disk usage data for external analysis or scripting.
