Project-VFS

This is a virtual file system (VFS) written entirely in C#. This project was developed by three friends. We divided the project into three main parts, each in a separate file. Responsibilities are documented in DivisionGuide.md.

Part One: Definitions

File: Definitions.cs

In this part we define the objects needed for the VFS. There are four main types:

• User
• Node
• Directory
• File

Both Directory and File inherit from Node.

Part Two: Commands

File: Commands.cs

Here we implement several Linux-like terminal commands as methods. There are 23 methods; the main methods are public and helper methods are private.

Part Three: Program

File: Program.cs

The program is the engine that receives input and safely invokes methods to respond. It receives user commands, processes them, then calls related methods. We use a large switch statement with goto labels.

The Program is divided into several parts:

• Initial values
• Lock Page
  • Used for user authentication (Tip: use skip to quickly enter the system as User1)
  • Or exiting the system
• System Page
  • VFS functionality

Extra commands

• lock -> goes to the Lock Page section.
• help -> shows an explanation of how to use the system commands.
