File Transfer System

A Java-based client-server application for transferring files over a network. This project implements a simple file transfer protocol allowing clients to upload and download files from a server.

Features

• Client-server architecture
• File upload and download
• Message logging and user management
• Chunked data transfer for large files

Prerequisites

• Java Development Kit (JDK) version 8 or higher
• Windows operating system (for the provided batch scripts)

Installation

1. Clone the repository:

   git clone https://github.com/Sayjad21/file_transfer_system.git
   cd your-repo-name
   

2. Ensure Java is installed:

   java -version
   

Building the Project

The project includes a compilation script. Run it from the project root:

compile.bat

This will compile all Java source files in the src/ directory and place the class files in the bin/ directory.

Running the Application

1. Start the Server: Open a command prompt in the project directory and run:

   run-server.bat
   

   The server will start listening on the configured port (default: check ServerConfig.java).

2. Start the Client: Open another command prompt and run:

   run-client.bat
   

   Follow the on-screen prompts to connect to the server and perform file operations.
