Description

-> In this project we emulate all data structures which are used by Operating system to manage File system oriented tasks.

-> As the name suggest virtual, its because we maintain all records in the Primary storage(RAM).

-> In this project we create all data structures which are required for File Subsystems like Incore Inode Table, UAREA, User File Descriptor Table, Super Block, Disk Inode List Block, Boot Block etc.

-> We provide all implementation of necessary system calls and command of File Subsystem as Open, Close, Read, Write, Lseek, Create, RM, LS, Stat, Fstat etc.

-> While providing the implementation of all above functionality we use our own data structures by referring Algorithms of UNIX Operating system.

-> By using this project we can get overview of UFS(Unix file System) on any platform.
