Multithreaded File Server

Overview

This project implements a multithreaded file server that allows multiple clients to upload and download files simultaneously. It uses:

• Python Sockets for networking
• Threading for concurrency
• SQLite Database for storing file metadata
• Tkinter GUI for user-friendly client interaction

The system supports reliable TCP-based file transfers with checksum verification to ensure data integrity.

Features

• Multiple clients can upload/download files concurrently
• TCP socket-based communication
• SHA-256 checksum verification for file integrity
• Tkinter GUI for client operations
• SQLite database for tracking uploaded files
• Automatic folder creation for uploads/downloads
• Configurable IP and port using config.ini
