Troubleshoot problems with file types and external devices
This error means that this file type isn't working on your Chromebook at this time.
Instead, try saving the file to Google Drive or another web application, then opening it in your browser.

If your storage device is supported, make sure your Chromebook is using the latest version of Chrome OS.

- Plug your storage device into another computer.
- Upload the files from the device to a cloud file system, such as Google Drive.
- Open your Chromebook, then open Google Drive to view the files.
