What is a NSF file (a file with file extension NSF)?
Files that contain the .nsf file extension are most commonly associated with the Lotus Notes collaboration software.
Lotus Notes incorporates features that include collaboration tools, email and business applications. These features allow users to share information across collaborative teams environments.
The database files that are created with the Lotus Notes software are saved with the .nsf file extension.
The .nsf file extension is also used by the Nintendo Entertainment System (NES) gaming software. These NSF files contain sound files that are used by the system. These files allow Nintendo music files to be played without the need for a user to open the actual Nintendo game.
