What is a BFSTP file?
A BFSTP file is an audio prefetch file used by a Nintendo Wii U or Switch video game. It contains data used to load the first three seconds of audio from a related .BFSTM (Binary Cafe Stream) file. Games use BFSTP files to pre-load the start of a BFSTM audio track, before loading and playing the rest of the track.
More Information
At times, programs perform prefetch operations to start loading data before it is needed. This allows the program to output the data more quickly (reducing lag time) when it is actually needed.
Various Wii U and Switch video games use BFSTP files to prefetch audio data (such as in-game background music). This allows the games to seamlessly play the start of an audio track while loading the rest of the track. Examples of games that use BFSTP files include Splatoon 2, Kart 8, Mario Kart 8 Deluxe, ARMS, and The Legend of Zelda: Breath of the Wild.
How to open a BFSTP file
BFSTP files are not meant to be opened by players. Nintendo video games that use BFSTP files load them as needed.
