Imagine a big room with many shelves where you keep all your toys. You have a list that tells you where each toy is kept. The list also includes the name of the toy and how many times you played with it. You always put the toy back in the same place after playing so that you can find it again easily later. This is what a file system does on a computer.
Now, imagine you want to keep a record of how many times you played with each toy each day. You could use different colored stickers to mark each toy depending on how much you played with it. This is what a hammer file system does.
In a hammer file system, each file and folder has a special attribute called 'history'. This keeps track of every action on a file or folder like who accessed it, when it was created or deleted, and how many times it was modified. It also stores multiple versions of each file so that you can go back in time and restore an older version if needed.
Using a hammer file system is like having a personal assistant who helps you keep track of everything you do with your toys. It's useful if you want to know where a file came from or if you need to recover an old version of a file.
