Opening NBU files

Did your computer fail to open a NBU file? We explain what NBU files are and recommend software that we know can open or convert your NBU files.

What is a NBU file?

Files that contain the .nbu file extension are commonly used by the Nokia PC Suite.

NBU stands for Nokia Back Up. Files that contain the .nbu file extension contain a backup of the data that is stored on a Nokia cellular phone. This information may include information about a user's contacts, calendars and other details that are stored on the phone.

If the Nokia phone becomes lost or damaged, the NBU files on the user's computer can be used to transfer the data to another phone from the files that have been saved by the Nokia PC Suite software program.
