It isn't so simple clearly to be explained here, but there are lots of resources related to this. I recommend you to research and read books more though.

Basically, a filesystem is a tool to determine how to read and save data by using a disk.

You need to integrate your code with a disk device driver, the filesystem you choose, and commands(or API) related to this.

The simpler version of your filesystem can be by using only memory (like memory disks) instead of disk-related things.

@sapsaldog I know what a filesystem dose, but I dont know how to code one in edit: this reply might be a bit silly

No offences, but I don't think there is someone who willing to teach this every detail at least on Github. Hope you find your answer.

thank you, also i did add a FizzBuss "command" to the shell

You need a disk driver first. Then you can start implementing a specification.

here are some examples: https://github.com/qloader2/qloader2/tree/master/src/fs

ngl you could probably implement a tar fs in the same amount of lines as a fizzbuzz command
