You can add Flash movie files (.swf files) to pages in Claro.
If you do, though, you should be aware they will not play on all mobile devices.
Most mobile operating systems now prevent the use of plug ins in their OS browser, and as a result Flash files will not be seen.
Because of this restriction of the mobile devices themselves, it is a best practice to create interactive content using Claro's interaction options or the Practice question options. These do not require Flash in the browser, so they work across any mobile device as well as on any laptop or desktop computer.
