.fsb creation help

Hello Community,
I need to make fsb files with music.
are fsb files like locked folders?
If so then i need (music.mp3 inside of music.fsb)
How do i do that? I put the song in the bank and clicked build but no fsb file got created.
FSB4 btw


An FSB is an “FMOD Sound Bank,” a proprietary file format used for dynamic audio sampledata and metadata. To create FSB4 files, you’ll need an older version of FMOD Soundbank Generator, such as the version shipped with FMOD Ex 4.38.
