Files is your Umbrel's built-in file manager. It works like the file browser on your computer — drag and drop, keyboard shortcuts, right-click menus, and all the usual ways to select and manage files.
Click Files in the dock on your home screen.
The sidebar gives you quick access to:
Most keyboard shortcuts you're used to work in Files — copy, paste, select all, undo, delete, and so on. A few handy ones:
Plug a USB drive into your Umbrel and it will appear under External storage in the sidebar. You can browse, upload to, and manage files on it just like your internal storage. External drives can't currently be used to store or run apps — apps run from your Umbrel's internal storage.
If your drive's format isn't supported, Files will offer to format it as exFAT (for compatibility with Windows, macOS, and Linux) or ext4 (for better performance with umbrelOS).
External storage is available on Umbrel Home, Umbrel Pro, and amd64 devices. It is not supported on Raspberry Pi — the Pi cannot reliably power external drives via USB, which can lead to data corruption.
For more on external storage, see External storage.
You can browse files on other Umbrels, NAS devices, or shared drives on your network, but network devices can't currently be used to store or run apps. Click the + next to Network in the sidebar to add a device. Devices on your network will be auto-discovered — if yours doesn't show up, you can enter the server details manually.
For more on network devices, see Adding network devices.
You can share any folder on your Umbrel so other devices on your network can access it. Right-click a folder and select Share over network. For more details, see Accessing your files from other devices.
Accidentally deleted or overwrote a file? If you have backups set up, you can use Rewind to jump back in time and recover files from past backups. Click Rewind in the sidebar, or right-click any file or folder and select Rewind.
