Introduction

DeckCrate is a fast, modern, cross-platform desktop file manager built with Flutter. It runs on macOS, Linux, and Windows.

Its defining trait: it’s driven by keyboard, mouse, and game controllers equally. Navigate with your controller’s D-pad, enter folders with A, go back with B. It’s designed with Steam Deck, ROG Ally, Legion Go, and couch use in mind — but it’s just as comfortable with a mouse and keyboard on the desktop.

Who it’s for

• Handheld gamers who want a real file manager in Desktop Mode without fighting a touchpad or on-screen keyboard.
• Keyboard-first users who want fast, discoverable shortcuts.
• Privacy-minded people who want a tool that stays on their machine — no telemetry, no analytics, no phone-home.
• Anyone who wants a lightweight, native-feeling file manager on macOS, Linux, or Windows.

The one big idea: device-independent actions

Every input source — a key press, a mouse click, or a gamepad button — funnels into a single action. The rest of the app only ever reacts to that action; it never cares whether you used a key or a pad. That’s why every feature is reachable from every input device, and why the controller feels like a first-class citizen rather than an afterthought.

In practice this means:

• The controller uses triggers as modifiers: hold LT for file operations, hold RT for selection.
• Start opens a command menu that can reach every action.
• The on-screen hint bar shows the relevant buttons as you hold a trigger.

Text entry needs a keyboard

Every feature is fully navigable with a gamepad on any device. Only text entry needs a keyboard: on Steam Deck, Steam Machine and other SteamOS devices the built-in virtual keyboard covers it; on PCs and laptops, where Steam’s virtual keyboard isn’t available, use your physical keyboard.

What it can do

A quick tour of the highlights:

• Browse the real filesystem with a sidebar of Places, Bookmarks, Devices, and network shares.
• Up to four tabs, each with its own folder, selection, and sort.
• Copy / cut / paste, rename and batch rename, move to Trash, and full undo / redo.
• Compress to ZIP and extract many archive formats, including password-protected ones.
• Mount disk images including ISO/IMG/DMG formats.
• Git integration, a built-in preview pane, an embedded terminal, and a fully localized UI in 36 languages.
• Zero telemetry — no analytics, no crash reporting, no phone-home. See the Privacy promise.
