What is an ADN file?

ADN files mostly belong to 1-2-3 by IBM. This was a Lotus product. Lotus was bought out by IBM.

How to open ADN files

You need a suitable software like 1-2-3 to open an ADN 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 ADN file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ADN file directly in the browser:. Just drag the file onto this browser window and drop it.
