VirtualFileSystem - Core

This project emulates file system functionality to create a virtual environment where users can perform file operations without interacting with a real disk

Virtual File System (VFS) – Purely Implementation in C

Overview :

This project is a custom implementation of a Virtual File System (VFS) that simulates the core functionality of the Linux/UNIX file system. It includes a custom shell to interact with the virtual environment. As the name suggests, the system is virtual because all file records are maintained in primary memory (RAM), making them temporary and non-persistent after termination. The project provides a practical understanding of system calls, file handling, memory management, and OS internals.

The project provides hands-on understanding of:

1. File handling
2. System calls
3. Memory management
4. Operating System internals

Key Features

    Custom Data Structures
    Implemented all major file system components from scratch, including:  
        Inode & Inode Table
        File Table
        User Area (UAREA)
        User File Descriptor Table (UFDT)
        Super Block
        Disk Inode List Block
        Data Blocks
        Boot Block

System Call Implementations

    Developed core file system calls using custom logic inspired by UNIX algorithms:
    open, close, read, write, lseek
    create, rm, ls
    stat

Custom Shell Interface

User-friendly CLI for executing commands.

Provides real-time interaction with the VFS
