What is an NBU file?
Backup file created by Nokia Suite (formerly Nokia Ovi Suite) or Nokia PC Suite; contains a backup of cell phone data and may include contacts, calendars, text messages, and other user data; used for restoring data to the same phone or transferring data to another phone.
NOTE: Nokia PC Suite became Nokia Ovi Suite, which was later renamed to Nokia Suite. Nokia Suite still creates backups using NBU files.
