A virtual file system (VFS) is programming that forms an interface between an operating system's kernel and a more concrete file system

The VFS serves as an abstraction layer that gives applications access to different types of file systems and local and network storage devices. For that reason, a VFS may also be known as a virtual file system switch. It also manages the data storage and retrieval between the operating system and the storage sub-system. The VFS maintains a cache of directory lookups to enable easy location of frequently accessed directories.

Sun Microsystems introduced one of the first VFSes on Unix-like systems. The VMware Virtual Machine File System (VMFS), NTFS, Linux's Global File System (GFS) and the Oracle Clustered File System (OCFS) are all examples of virtual file systems.
