File System Manager

Overview

The File System Manager is a comprehensive implementation of a virtual file system. It provides a user-friendly interface in the command line for interacting with the file system, supporting a hierarchical structure with features such as:

• Adding, deleting, renaming, copying, and moving files and directories.
• Symbolic link management.
• Directory size calculation.
• DFS-based display of the file system structure.

Components

1. Main File (main.cpp)

Purpose:

• Serves as the entry point of the program.

Key Features:

• Includes userIOControl.hpp.
• Contains a simple main function that calls the runner() function.
• Delegates all functional operations to the runner() function.

2. File System Implementation (fileSystem.hpp)

Purpose:

• Implements the core functionality of the File System Manager.

Key Classes:

a. FileSystemNode Class

Description: Represents files or directories in the file system.

Attributes:

• name: Name of the file or directory.
• isFile: Boolean flag differentiating files from directories.
• children: A map storing child nodes for hierarchical traversal.
• size: Integer storing file size (default is 0 for directories).
• symbolicLinks: Vector to handle symbolic links to other nodes.

Constructor: Initializes node attributes based on input parameters.

b. FileSystemTree Class

Description: Represents the hierarchical structure of the file system.

Functionalities:

1. Traversal:
   • Implements DFS traversal to display the file system structure.
   • Includes symbolic link representation.
2. Insertion:
   • Adds files or directories to the structure.
   • Initializes attributes like isFile and size based on user input.
3. Deletion:
   • Deletes files or directories.
   • Cleans up associated symbolic links.
4. Search:
   • Searches for files or directories by name.
   • Includes symbolic link traversal in the search.
5. Directory Size Calculation:
   • Recursively computes the total size of a directory, including files and subdirectories.
6. Symbolic Links:
   • Supports adding symbolic links between nodes.
7. Copy and Move Operations:
   • Allows copying and moving files or directories within the structure.
8. Renaming:
   • Enables renaming of files or directories.

Helper Methods:

• dfsHelper: Implements recursive DFS traversal for displaying the file system.
• deleteNode: Handles recursive deletion of nodes and their children.
• calculateDirectorySize: Computes the total size of a directory.
• deepCopy: Creates a deep copy of a file or directory for copy operations.

3. User Interaction Handler (userIOControl.hpp)

Purpose:

• Provides a user interface for managing the file system.

Key Features:

a. Helper Function

• splitPath: Splits a user-provided path string into components for hierarchical traversal.

b. Menu System

• displayMenu: Displays a menu of available actions to the user.

c. Runner Function

Manages the interaction loop between the user and the file system.

Provides the following options:

1. Display File System: Displays the hierarchical structure using DFS traversal.
2. Add File/Directory: Prompts the user for details and inserts the item into the file system.
3. Delete File/Directory: Deletes the specified file or directory.
4. Search for File/Directory: Searches the file system by name.
5. Calculate Directory Size: Computes the total size of a specified directory.
6. Add Symbolic Link: Creates a symbolic link from one node to another.
7. Copy File/Directory: Copies a file or directory to a new location.
8. Rename File/Directory: Renames a file or directory.
9. Move File/Directory: Moves a file or directory to a new location.
10. Exit: Exits the program gracefully.

User Input Handling:

• Uses cin and getline to ensure proper handling of strings and integers.

How to Compile and Run

1. Compile the program:

   g++ -o file_system_manager main.cpp fileSystem.cpp userIOControl.cpp

2. Run the program:

   ./file_system_manager
