Troubleshoot file type and external devices

I get an "Unknown file type" error message when I try to open a file

This means the file type won’t work on your Chromebook at this time. You can try using a web application to view the file. For example, you can upload most documents, presentations, and spreadsheets to Google Drive and view them in your browser.
