File System Simulation

This project is a C program that simulates basic file system functionality. It covers the basic features of a real file system and demonstrates how file operations work.

✨ Features

• Creating, deleting, reading, and writing files
• Renaming and moving files
• Copying and comparing files
• Disk defragmentation
• Integrity checking
• Backup and restore
• Log system

🛠 Requirements

• GCC compiler
• Make
• POSIX-compliant operating system (Linux, macOS, WSL)

Usage

To run the program: You can go to the project file location in the terminal, compile the program with the make command, and run it directly.

• Creating a file:

• List of files:

• Append some data to file and print the content:

• Truncate the file, read data between two offsets:

Basic Commands

• fs_init(): Initializes the file system
• fs_format(): Formats the disk
• fs_create(filename): Creates a new file
• fs_delete(filename): Deletes a file
• fs_write(filename, data, size): Writes data to a file
• fs_read(filename, offset, size, buffer): Reads data from a file
• fs_append(filename, data, size): Appends data to a file
• fs_rename(old_name, new_name): Renames a file
• fs_copy(src, dest): Copies a file
• fs_mv(old_name, new_name): Moves a file
• fs_ls(): Displays the file list
• fs_cat(filename): File contents Displays
• fs_diff(file1, file2): Compares files
• fs_defragment(): Defragments the disk
• fs_check_integrity(): Checks integrity
• fs_backup(backup_filename): Makes a backup
• fs_restore(backup_filename): Restores from a backup

Error Management

The program checks and manages the following error conditions:

• File not found
• Insufficient disk space
• Invalid file operations
• Disk integrity errors
• Out of memory

Log System

All transactions are recorded in the log.txt file. This file will be created automatically. Log records include:

• Transaction time
• Transaction type
• Transaction result
• Error messages
