Distributed File System using Socket Programming

This project implements a basic Distributed File System (DFS) in C using socket programming. It was developed as part of the COMP-8567: Operating Systems course at the University of Windsor during Summer 2025.

🧱 Project Overview

The system mimics a multi-server file storage mechanism where:

• All clients interact only with Server S1
• Based on file extensions, S1 routes files to other backend servers:
  • .c → stored in S1
  • .pdf → routed to S2
  • .txt → routed to S3
  • .zip → routed to S4

Each server runs on a different terminal and communicates via sockets.

## 🚀 Compilation

gcc -o S1 servers/S1.c
gcc -o S2 servers/S2.c
gcc -o S3 servers/S3.c
gcc -o S4 servers/S4.c
