This project focuses on the low-level implementation of the filesystem and file management, specifically targeting the ext2 filesystem, which is popular on Linux.

• Read Core Structures: Parse the filesystem image to extract and display the contents of the superblock and block group descriptors.
• Traverse Directories: Starting from the root directory, your program must be able to recursively traverse all subdirectories, printing the complete layout of the filesystem.

g++ *.cpp -o main && ./main <img_file>

The program starts from main.cpp, which runs in an infinite loop (until input is exit).

There are a few commands implemented so far:

• info (show info, similar to dumpe2fs)
• ls (show info about current directory)
• cd <dir_name> (change directory to <dir_name>)
• cat (read contents of files)
• write <"text"> <filename> writes text to the file.

• Reading general info of the filesystem.
• Traversing through the file structure.
• Outputting the contents of files.
• writing to a file

The program is divided into two major classes: Disk and DiskUtil. Their names explain enough about the classes.

Disk is for functions related to class data and storing data in memory.

DiskUtil is for miscellaneous functions and other commands on the disk.

There is a file struct.hpp which contains all structs of the program.
