TCP File Transfer

This project provides a simple TCP file transfer server and client using Winsock for Windows and POSIX socket APIs for Unix-like systems. The server sends requested files to the client upon request.

Overview

• Server (server.cpp): Listens for incoming client connections, handles file requests, and sends requested files to the client.
• Client (client.cpp): Connects to the server, requests files by name, and saves the received files locally.

Requirements

• Windows: Visual Studio or another C++ compiler that supports Winsock.
• POSIX Systems: A POSIX-compliant system (Linux, macOS) with a C++ compiler.
• C++17 or later: The code uses features from C++17, such as std::filesystem and std::atomic, which are not available in earlier versions of C++.

Building

To build the server and client applications, use the provided server.cpp and client.cpp source files. Ensure that you link against the ws2_32.lib library on Windows.

Build Instructions (Visual Studio)

1. Open Visual Studio.
2. Create a new project or open an existing one.
3. Add server.cpp to the project for the server application and client.cpp for the client application.
4. Configure the project to link against ws2_32.lib (typically found under project properties -> Linker -> Input).
5. Build the project.

Build Instructions (POSIX Systems)

1. Open a terminal.
2. Navigate to the directory containing server.cpp and client.cpp.
3. Compile the source files using a C++ compiler. For example:

   g++ -o server server.cpp
   g++ -o client client.cpp
