Okay kiddo, so do you know what a cow is? It's a very special animal that gives milk to people. And do you know what EXT3 is? It's a special way of storing files on a computer.
Now, imagine if you had a cow that could give you milk and also make a copy of itself every time it gave you milk. That would be pretty neat, right? Well, that's kind of what ext3cow does with your files.
When you save a file on your computer with ext3cow, it not only saves the original file, but it also saves a copy of that file every time it gets changed. So it's like having a cow that gives you milk and also makes a copy of itself every time it gives you milk.
This is really helpful if you ever need to go back to an older version of a file, because you can just look at the copy of the file from before the changes were made. It's kind of like going back in time to see what the file looked like before it was changed.
So that's ext3cow in a nutshell. It's a special way of storing files on your computer that lets you go back in time and see old versions of your files. And just like a cow that gives you milk and makes copies of itself, it's pretty useful!
