This format is designed to store structured data such as tables, queries, and forms. It is best managed using Microsoft Access.
If you suspect your A2 file is not a database but a CAD drawing, note that some applications use the same extension for Alphacam CAD drawings. These files store design data and require appropriate CAD software to open.
