Alright kiddo, so imagine you have a toy car that you can only play with in one specific place at home. But what if you want to bring it over to your friend's house to play with?
Well, computers have something similar to toy cars called files. And sometimes when you want to bring a file from one computer to another, there's a problem.
One way they used to solve this problem was by using something called a vfat patent. This is basically like a special key that unlocks a way for different computers to be able to read and write files in the same way.
But some people didn't like this vfat patent, because they thought it was unfair to have to pay for the key. They thought that everyone should be able to use this way of reading and writing files without having to pay for it.
So, after a while, the people who own the vfat patent decided to stop charging money for it. Now, pretty much everyone can use it without any trouble. And that's how the vfat patent helped make it easier to share files between different computers.
