Virtual File System

A Virtual File System (VFS) is a layer in a computer that provides a uniform way to access files and directories, regardless of the actual storage method or device. It acts as an intermediary between user programs and different file systems, allowing applications to read, write, or manage files without needing to know the details of where or how they are stored. This abstraction simplifies working with multiple storage types (like hard drives, USBs, or network locations) and ensures consistent access across different systems. Essentially, VFS makes file management seamless and unified for users and applications.
