Opening a NAB File
The NAB file type is primarily associated with GroupWise.
What is a NAB file?
NAB files mostly belong to GroupWise. The NAB file extension can refer to different file types depending on its creation environment.
GroupWise Address Book: Many NAB files are encoded in UTF-8 and serve as the address book for Novell GroupWise, storing contact information used in an email and collaboration system.
Java Serialized Object: Other NAB files are Java serialized objects. In these cases, the file acts as a license file for GRAPHISOFT products and is managed within a Java environment.
Unity Game Asset Bundle: Some NAB files use the UnityFS format. They are asset bundles used to package game assets in Unity-based projects.
Use the appropriate application for each type:

If you cannot open your NAB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a NAB file directly in the browser:.
