Send File Setup

This guide explains how to configure your Windows AIM client to send files over the Internet using the Send File feature. If you only need to receive a file, no additional setup is required.

⚠ Security Notice: Doing this makes your IP address visible to the recipient. Opening a port on your home network allows inbound Internet traffic to reach your computer on that port. Use careful judgment and consider the security implications before proceeding. Only do this with people you trust.

1. Configure AIM Port

  1. Open the AIM Preferences window.
  2. Select File Transfer from the sidebar or menu.
  3. In the Port number to use field, enter a high port number such as 4000.

2. Set Up Router Port Forwarding

  1. Log in to your router’s admin interface.
  2. Create a new port forwarding rule:
    • Forward TCP port 4000 (or the port you chose)
    • Send that traffic to the local IP address of the computer running AIM
  3. Save or apply the changes.

3. Send a File

  1. Start an IM with a friend.
  2. Go to File > Send File... (or use the appropriate menu option in your AIM client).
  3. Choose the file you want to send.
  4. Your friend should now receive a prompt to accept or decline the file.
  5. If the receiver is on the Internet and your port forwarding is correct, the direct file transfer should succeed.
