How to open DA4 files
You need a suitable software like SeeYou to open a DA4 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your DA4 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a DA4 file directly in the browser:. Just drag the file onto this browser window and drop it.
