What is a Distributed File System?

A file system that stores files across many machines, while letting you use them as if they sat on one local disk, is called a distributed file system (DFS). The files physically live on multiple servers, often in multiple locations. You still see one folder tree, one set of file names, and one place to read and write.

Think of a large library with many branch buildings but a single catalog. You search the catalog, request a book, and the book arrives at your desk. You never need to know which building stored it
