What is an NSF file?
An NSF file is an audio file saved in the NES Sound Format. It likely contains music exported from a Nintendo Entertainment System (NES) game. However, some NSF files contain original compositions, created by NES and chiptune enthusiasts using various music trackers.
Developer Kevin Horton created the NSF format to allow NES enthusiasts to save and transfer NES music data in a compact, easy-to-use format. Using various ripping tools, gamers can extract all a game's music and package it in a single NSF file. Each NSF file also contains a small file header, which details various metadata (such as the name of the game from which the file was created).
Often, gamers share NSF files they've created from NES games online, to allow other gamers to download and listen to that music in a media player. However, some chiptune music enthusiasts enjoy creating their own NSF music, using NES music composition programs such as FamiTracker and BleuBleu FamiStudio.

Lotus Notes Database

An NSF file may also be a database file used by IBM Lotus business software. It is saved in the Notes Storage Facility (NSF) format, which stores data in document units called "notes." NSF files are used for storing collaborative business information such as mail and calendar data.
NSF files are often hosted by a Lotus Domino server, and they can be downloaded by Lotus Notes clients to work with a fully functional database in offline mode. If the client makes changes to the database, Domino includes the facilities to synchronize the changes back to the master database. NSF files can also be used for the process of data replication.
NOTE: NSF files may also serve as a Domino Web application that is hosted on a web server, where the URL has a trailing .nsf string. These files include the Domino Web Service Design Element, which enables Web access.
