DeckCrate, a fully controller-operable file manager, is now available on Steam for €2.54 (15% off until August 14, regularly €2.99).
The tool is built specifically for Steam Deck and other handhelds, controllable entirely with a gamepad or traditional mouse/keyboard.
DeckCrate offers file operations like copying, moving, batch renaming, and compression, plus a preview pane for text/code/images, disk image mounting (ISO, IMG, DMG), an embedded terminal, and recursive search. Git-aware status badges, tabs, bookmarks, and a recent-files list round it out - all without telemetry.
Every single feature is reachable from a controller - no touchpad-poking required.
