3.4.1 Browse and transfer files

The Files UI has three parts: the folder tree on the left, the file list on the right, and the task bar at the bottom.

Layout

Area	What it shows
Left folder tree	Common root folders on device and children of what you expanded
Right file list	Files in the current folder: name, size, modified time, permissions
Top address bar	Type a path to jump quickly (e.g. `/opt/tros/humble/lib/`)
Top breadcrumbs	Each segment can be clicked
Bottom task bar	Active uploads/downloads with speed and ETA

Method	How
Drag and drop	Drag files or folders from the PC onto the Studio window
Upload button	Upload in the toolbar opens a file picker
Bulk upload	Select multiple files or a whole folder in one shot

Progress appears in the task bar. Writes to sensitive paths (e.g. /sys, /proc) follow access-control rules — see 3.4.3 Paths you cannot edit.

Method	How
Download icon	Icon next to a file downloads to your PC default download folder
Bulk download	Select multiple files → right‑click Download selection → gets a ZIP
Drag out	On hosts that support it, drag to desktop or Explorer

Right‑click a file or folder:

Action	Purpose
New file	Creates an empty file in this folder
New folder	Creates a subfolder here
Rename	Renames the file or folder
Delete	Deletes the selection (Delete key works too)
Copy full path	Copies absolute path to clipboard
Open terminal here	Opens a new Terminal tab with `cd` to this folder

The search box searches file names only in the current folder (no recursion), avoiding stalls on huge trees.

For wider search, tell AI Dock: “Under /opt/tros, find .hbm files” — Moss can run appropriate find commands.

Path	Use
`/userdata/`	RDK‑recommended writable user area (survives image refresh)
`/tmp/`	Temp files cleared on reboot
`/opt/tros/humble/`	TROS install (lib, share, include)
`/home/<user>/`	User home
`/var/log/`	System logs
`/etc/`	System configuration
