File extension nbu is primarily used for backup files of Nokia phones created with Nokia PC suite 6.82 and later.

The typical nbu file contains complete backup of phone, including contacts, messages and other data located in internal memory of the phone as well as phone SD card.

This nbu file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
