Peer-to-Peer File Sharing System

This repository implements a peer-to-peer (P2P) file sharing system using socket programming in Python. It includes two components:

• File Sender: Allows the user to select and send files to a receiver.
• File Receiver: Receives files from a sender and saves them to a specified directory.

The system includes a graphical user interface (GUI) for both sender and receiver, making it user-friendly and intuitive.

• Pause, Resume, and Stop Controls: Flexible file transfer management.
• Transfer History: Logs file transfers for future reference.

Sender

• File Selection: Allows users to select multiple files for transfer.
• Progress Tracking: Displays file transfer progress, speed, and estimated time remaining.
• File History: Logs sent files with details such as filename, size, and timestamp.

Receiver

• Save Directory Selection: Users can specify where to save received files.
• Transfer Progress: Tracks the progress, speed, and estimated time for incoming files.
• History Management: Logs received files for reference.

Usage

Running the Receiver

1. Open the terminal and run:

   python p2p_receiver.py

2. Use the GUI to:
   • Set the save directory.
   • Start the server to begin listening for file transfers.
   • Pause, resume, or stop the file transfer as needed.
   • View transfer history.

Running the Sender

1. Open the terminal and run:

   python p2p_sender.py

2. Use the GUI to:
   • Select files to send.
   • Provide the receiver's IP, port, and authentication password.
   • Monitor the transfer progress.
   • Pause, resume, or stop the transfer as needed.
   • View transfer history.

Authentication

The sender and receiver use a predefined password (default_password in the receiver code). Ensure that both sender and receiver use the same password for successful authentication. You can change the default password by editing the auth_password variable in both scripts.

Notes

• Transfer Interruptions: Transfers can be paused, resumed, or stopped at any time using the provided controls.
• Transfer Speed: The system dynamically calculates and displays the transfer speed in real-time.
• Compatibility: Ensure that the sender and receiver are running on the same network or have the necessary network configurations for connectivity.
