Okay, so when you have a computer, you can save your pictures, videos, and documents on it. But what if you have many computers and you want to share those files with other people? That's where a distributed file system comes in!
Think of it like a big bookshelf that holds all your files. But instead of just one bookshelf, there are many bookshelves in different locations. Each bookshelf has some of the same books, but also some unique ones. And you can access any bookshelf from any computer, so it's like you have all the books with you no matter where you are!
Microsoft's distributed file system is called DFS, and it helps organize all these different bookshelves so you can easily find the files you need. It also makes sure that if one bookshelf gets full or goes offline, you can still access your files from another bookshelf.
So that's basically what a distributed file system does: it helps you share your files across many computers, so you can access them from anywhere and never lose them. Cool, right?
