VFS (Virtual File System)

The Virtual File System (VFS) is a software layer in an operating system that provides a uniform interface for accessing various types of storage devices and file systems. It allows applications to read, write, and manage files without needing to know the specific details of different storage formats or hardware. VFS acts as a translator, connecting high-level commands to the underlying file systems (like NTFS, FAT, or ext4), making file operations consistent and seamless across diverse storage options. Essentially, it simplifies file management by abstracting the complexities of different file system implementations.
