Virtual Filesystem

A Virtual Filesystem (VFS) is an abstraction layer in an operating system that allows different types of storage devices and filesystems to be accessed uniformly. It acts like a translator, enabling software to interact with various storage formats—like hard drives, SD cards, or network locations—without needing to know their specific details. The VFS manages these different systems seamlessly, presenting a consistent way to read, write, and navigate files, thereby simplifying data management across diverse storage media while hiding their underlying complexities.
