How to Share a Folder Between Two Computers via Wi-Fi in Windows 7: A Complete Guide

Sharing files between two computers via Wi-Fi Windows 7 — a task that may seem difficult only at first glance. Many users still work with this version of the OS, despite its outdated status, and are faced with the need to organize network access to folders without using flash drives or external drives. Unlike modern versions of Windows, where the process is partially automated, Windows 7 requires manual configuration of network settings, permissions, and protocols.

In this article we will look at three key stages: network preparation (including checking the connection and setting up a workgroup), creating and setting up a shared folder, and troubleshooting common errors such as lack of access or computers being invisible on the network. We will pay special attention security — how to restrict access to only the devices you need and prevent data leaks. If you've never set up a local network before, don't worry: the instructions are tailored for beginners, with explanations for each step.

1. Preparing the network: checking the connection and setting up a workgroup

Before creating a shared folder, make sure both computers are connected to the one Wi-Fi networkThis is the basic requirement for file sharing. If one PC is connected via cable and the other via Wi-Fi, but to the same router, that's also acceptable.

Check your connection:

1. Click Win + R, enter cmd and run the command ping [IP address of the second PC].
2. If the answers are received without any losses (for example, Reply from 192.168.1.2: number of bytes=32...), there is a connection.

If ping doesn't work, check firewall or router settings - local traffic may be blocked.

Next you need to configure the same working group on both computers:

1. Right click on Computer → Properties → Additional system parameters.
2. In the section Computer name click Change.
3. In the field Working group please specify the same name (eg. WORKGROUP) and restart your PC.

2. Setting up network discovery and file access

By default Windows 7 may block access to network resources. To avoid this, enable network discovery and configure sharing settings:

• 🔧 Open Control Panel → Network and Sharing Center.
• 📡 In the left menu, select Change advanced sharing options.
• 🔒 For profile Home or work turn on:
  • Network discovery;
  • File and printer sharing;
  • Allow Windows to manage connections.
• 🔄 Save the changes and restart your computer.

If after these steps the computers still cannot see each other, check the settings DNS suffix:

1. Open Network connections (through Control Panel).
2. Right-click on the active connection → Properties → Internet Protocol version 4 (TCP/IPv4).
3. Click Additionally and in the section DNS make sure the option is disabled Use connection DNS suffix.

3. Creating and configuring a shared folder

Now let's move on to the main part: creating a folder that will be accessible from another computer. Select the folder you want to share (for example, D:\General Documents), and follow these steps:

• 📁 Right-click on the folder → Properties → tab Access.
• 🔓 Click Share and select from the drop-down list All (or specify a specific user).
• 🔐 Click Share, then go to the tab Security.
• 🛡️ Click Change → Add → enter All → OK.
• 📋 In the column Allow tick the boxes Full access (or just Reading, if you need to limit rights).

Important! If you choose All (Everyone), all devices on the network, including smartphones and smart TVs, will have access to the folder. For security, it's best to create a separate user with a password (more on that in the next section).

4. Setting up users and passwords for secure access

By default Windows 7 Requires authentication to access shared resources. If you use a different account on the second computer, you will need to:

1. Create identical accounts on both PCs:
   • Open Control Panel → User Accounts.
   • Select Manage another account → Add a user.
   • Please enter your username and password (e.g. User_Share with a password 12345Qwerty!).

1. Press Win + R → enter regedit.
2. Go to the path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa.
3. Find the LimitBlankPasswordUse parameter and set the value to 0.
4. Restart your computer.

1. Open Command Prompt as administrator.
2. Enter the following in turn:
netsh int ip reset
netsh winsock reset
3. Restart your PC.
