SPAN Finder

SPAN Finder is an open-source, blazing-fast file manager for Windows built with C# and WinUI 3. Designed for power users and developers who refuse to compromise, it replaces the default Windows Explorer with a highly optimized environment centered around a Miller Columns layout (similar to macOS Finder).

Beyond its core multi-column navigation, SPAN Finder offers a robust set of advanced tools that significantly enhance daily productivity. It combines the elegance of seamless folder navigation with heavy-duty features like true dual-pane split views, full multi-tab support with session restore, and an instant macOS-style "Quick Look" preview panel.

Key Features:

Advanced Navigation: Combine Miller Columns with a true Dual-Pane (Split View) layout and full Multi-Tab support (with tear-off and duplication).

Developer-Ready: Built-in Git integration (status badges), FTP/SFTP remote connections, terminal integration, and a Hex binary viewer.

Powerful Preview Panel: Press 'Space' to instantly preview 10+ file types including syntax-highlighted code, media files, PDFs, and fonts.

Heavy-Duty Tools: Regex batch renaming, full undo/redo operation history, and type-ahead smart search.

Keyboard-First Design: Over 30 keyboard shortcuts allowing full navigation without touching the mouse.

Highly Customizable: 10 built-in themes including Dracula, Tokyo Night, Catppuccin, and Nord, with adjustable UI scaling.

Zero-Lag Performance: Engineered with Async I/O on .NET 8, easily handling directories with over 14,000+ items without freezing the UI.

Available for free on the Microsoft Store for easy installation and automatic updates, with the complete source code hosted on GitHub.
