A DOS/Linux extensible file system

The authors describe the architecture for an extensible virtual file system (VFS) which allows for the incorporation of a new file system along with existing ones. They describe extending file systems in the context of the DOS operating system. The new VFS file systems in the DOS environment will add features such as strongly typed well defined interfaces, location independent object invocation mechanism, and a flexible naming architecture. File systems such as the Second Extended File System (EXT2FS) and Minix were implemented for DOS to asses the practicality of the architecture.
