17. How to Connect Two Computers and Share Files

Connecting two or more computers together allows you to transfer files and share resources between them. This guide will walk you through the various ways to connect computers and enable file sharing.

Using a Router and Network cables

The easiest way to connect computers is by using a router and Ethernet cables.

What you need

• Router – This connects to your modem and creates a local network. Any wired or wireless device can connect to the router’s network.

• Ethernet cables – These wired cables connect devices directly to the router. You need one cable per computer.

• Both computers – They should be on and connected to the router.

Steps

1. Connect both computers to the router using Ethernet cables.

2. On each computer, open File Explorer.

3. Click on Network in the left pane. You should see the other computer listed.

4. Double click the other computer to access its shared files and folders.

5. To share a folder from one computer to the other, right-click on it and select Share.

This allows basic file sharing between computers on a local network.

Using a Wireless Router

A wireless router lets you connect computers wirelessly using Wi-Fi, without any cables.

What you need

• Wireless router – This connects to your modem and creates a Wi-Fi network.

• Both computers – They should have Wi-Fi capability and be on the same wireless network.

Steps

1. Make sure both computers are connected to the same wireless network.

2. Follow steps 2-5 above to access and share files over the wireless network.

This provides the convenience of wireless access without the hassle of wires.

Using Ad-Hoc Wireless Network

You can connect two Wi-Fi enabled computers directly without a router using an ad-hoc wireless network.

What you need

• Both computers – They should have built-in or external Wi-Fi capability.

Steps

1. On one computer, open Network Settings and create a new ad-hoc wireless network. Set a network name and security key.

2. On the other computer, join the same ad-hoc network using the name and key.

3. Follow steps 2-5 above to access and share files over the ad-hoc connection.

This lets you connect just two computers wirelessly without a router. But the range will be limited.

Using a Crossover Cable

A crossover cable can directly connect two computers without a router or hub.

What you need

• Crossover cable – This special Ethernet cable can connect two devices directly.

• Both computers – They should have Ethernet ports.

Steps

1. Connect the two computers directly using the crossover cable.

2. Follow steps 2-5 above to access and share files over the direct cable connection.

This offers a simple wired connection without any router. But only works for two computers.

Sharing Files Using USB drive

You can transfer files by copying them to and from a USB flash drive.

What you need

• USB flash drive – Should have enough capacity for your files.

• Both computers – They should have USB ports.

Steps

1. Copy files from one computer to the flash drive.

2. Plug the flash drive into the other computer.

3. Copy files from the flash drive to the other computer.

This lets you manually transfer files using a common storage device. But is relatively slow.

Summary

• Using a router provides the easiest network file sharing between computers.

• A wireless router offers greater flexibility without cabling.

• An ad-hoc wireless connection lets you connect just two Wi-Fi devices directly.

• A crossover cable offers a simple wired connection for two computers.

• A USB drive allows manual file transfer through a common storage device.
