Flux is a minimalist, high-performance file manager for Linux. It’s built for those who love the clean look of GNOME but want a tool that stays out of their way.

Most file managers try to do everything. Flux tries to do one thing perfectly: letting you browse your data at light speed without the visual noise.

• Zero Clutter: We replaced bulky buttons with a smart, dynamic header that shows you exactly what you need to know.
• Asynchronous Heart: Got a folder with 5,000 high-res wallpapers? Flux won't sweat. It uses a throttled async pipeline to load thumbnails without ever freezing the window.
• Shortcut First: Flux is designed for power users who prefer the keyboard over hunting for tiny icons.

Flux is built around the "Config-Driven" philosophy. You control the logic, we provide the speed.

• Insert: Add selection or current folder to list.
• Ctrl + Insert: Pin selection/folder to sidebar permanently.
• Tab: Cycle to the next folder in the list.
• Ctrl + End: Clear the entire list.

Everything is managed via ~/.config/flux/config.toml. Want to add a custom folder to your sidebar or change the default sorting? Just edit the text file. It's that simple.

Custom Actions: You can define your own right-click commands. Add "Open in VS Code" or "Optimize Image" by linking a simple shell command in your config.

• cairo-gobject → vector graphics rendering for custom ui elements.
• graphene-1.0 → hardware-accelerated 2d/3d transformations.
• gio-2.0 → virtual file system operations and directory monitoring.
• glib-2.0 → core event loop and data structure management.
• gobject-2.0 → the type system required for rust-to-c interoperability.
• pango → font handling and phonetic text layout.

• ffmpeg → video decoding and frame capture.
• ffprobe → extraction of technical media metadata.
