How to Create a Shared Folder on a Wi-Fi Network: A Step-by-Step Guide

Creating local data storage on your home or office network is a fundamental step towards convenience and efficiency. Instead of transferring files on flash drives or sending them to yourself via instant messaging, you can set up public access Access the resources of a single computer for all devices connected to your router. This allows you to instantly share documents, photos, and media files between laptops, tablets, and even Smart TVs.

The setup process requires attention to detail, as Windows operating systems by default seek to protect the user by blocking external connections. You'll need to change several network profile settings, configure access rights, and possibly adjust security settings. Despite the apparent complexity, the entire process takes no more than 15-20 minutes, even for an inexperienced user.

It is important to understand that for the file sharing mechanism to work stably, all devices must be in the same subnetsTypically, a router assigns addresses automatically, but if you have a complex network infrastructure with multiple access points or VLANs, additional routing settings may be required. In this article, we'll look at a classic scenario for a standard home network.

Preparing the network environment and checking the connection

Before setting up access rights, you need to ensure that basic connectivity between devices is established correctly. Users often try to share a folder when the computers are physically unable to see each other due to the incorrect network profile type. Windows divides networks into "Public" and "Private," and for shared folders to work, it's crucial that the active network profile be active. private profile.

Check if all devices are connected to the same Wi-Fi network. If you have a dual-band router broadcasting networks named "Home_2.4" and "Home_5G," make sure all devices are connected to one of them, although modern routers often combine them into a single SSID. You can use the built-in command line utility to check the connection.

Replace the IP address in the command with the address of the target computer you plan to connect to. If responses are received, then the physical and IP layers are working correctly. If you see the message "Timeout exceeded," the problem lies deeper—perhaps in the firewall settings or client isolation on the router itself.

It's also worth paying attention to the names of computers on the network. They must be unique, otherwise an addressing conflict will occur, and Windows won't be able to determine which device you're accessing. You can change the name through the system settings, which will require a reboot.

⚠️ Note: Some routers have a feature called "Wi-Fi Client Isolation" (AP Isolation), which prevents devices connected wirelessly from communicating with each other. If pinging is not working, check the wireless settings in your router's web interface and disable this feature.

Setting up sharing options in Windows

The central hub for managing your computer's visibility is the "Sharing Settings" panel. This is where you decide whether your PC is visible to other users and whether they can read or write data. Open "Control Panel," go to "Network and Internet," then "Network and Sharing Center," and select "Change advanced sharing settings."

In the window that opens, you'll see several profiles: "Private" (or "Current Profile") and "Guest or Public." We're interested in the first tab. Here, you need to enable the "Turn on network discovery" switch and check the "Turn on file and printer sharing" box. Without these two options, your computer will be "invisible" to your neighbors via Wi-Fi.

Below is the "All Networks" section, which requires special attention. This section contains settings that affect security and authentication methods. If you want to allow access to folders without a password (for example, for a media player or game console), select "Turn off password-protected sharing."

• 📁 Network discovery - allows the computer to announce its presence on the network and see other devices.
• 🔗 File sharing — allows access to shared resources.
• 🔐 Password protection - requires entering user credentials when attempting to access from another PC.

After making changes, be sure to click "Save Changes." Sometimes the system may prompt you to confirm administrator privileges. If you've enabled network discovery but the computers still aren't visible in the "Network" list, try restarting the discovery service or simply rebooting your PC.

Creating and sharing a folder

Once the network environment is prepared, you can begin creating the resource. You can use any existing folder or create a new one specifically for file sharing. It is recommended to create such folders at the root of the drive or in the user profile, but not in Windows system directories to avoid access rights issues.

Right-click the folder, select "Properties," and then go to the "Sharing" tab. There are two options: simple ("Sharing") and advanced ("Advanced"). For full functionality on a corporate or complex home network, it's best to use advanced settings, as they provide complete control over permissions.

In the Advanced Settings window, check the "Share this folder" box. In the "Share Name" field, you can leave the default name or enter a custom name that the user will see when connecting. Click the "Permissions" button to configure who can do what with the files.

Menu path: Folder Options → Access → Advanced Settings → Permissions

By default, the "Everyone" group may be listed here. Select it and select the desired permissions: "Read" will only allow viewing and copying files, "Modify" will add editing and deletion capabilities, and "Full Control" grants unlimited rights, including changing permissions (use with caution).

⚠️ Important: The "Security" tab in the folder properties is also critical. Even if you grant full permissions in the sharing settings, if the user doesn't have NTFS permissions on the "Security" tab, access will be denied. Make sure the "Everyone" user or group is added there as well.

Setting up access rights and user groups

The Windows permissions system is based on user accounts. When you grant access, you're essentially telling the system which users are allowed to interact with the resource. If you've disabled password protection, the system automatically allows the guest user access. If you've enabled it, authorization is required.

To add a specific user, click "Add" in the permissions window. Enter the username (login) they use to log in to this computer, or the name of a group (e.g., Administrators or Users). This allows for flexible access control: for example, an accountant can be given edit rights, while an intern can only have read rights.

If the computers are on a domain (office network), you can specify domain accounts here. On a home network (workgroup), local accounts are used.

• 👤 Local users — accounts that exist only on a specific PC.
• 🏢 Domain users — centralized server accounts (Active Directory).
• 🌐 Group "All" - anyone who has access to the network (less secure).

For increased security, it's recommended to create separate accounts with limited privileges for network access, rather than using the administrator account. This minimizes the risk in the event of a network compromise.

Connecting to a shared folder from other devices

Once a folder is shared, you can connect to it from any device on the network. On another Windows computer, open File Explorer and enter the IP address or computer name of the host computer in the address bar. The address format is \\192.168.1.10 or \\ComputerName.

If all settings are correct, a window will open displaying the contents of your shared folders. For ease of use, you can right-click the desired folder and select "Mount as network drive." This will display the folder as a separate drive (e.g., Z:) in "My Computer," making it easier to work with documents.

Android and iOS devices can also access this data. To do this, you'll need a file manager app that supports SMB (such as File Commander, VLC Player, or the built-in Files app on iOS). In the app, select "New Connection" → "Local Network" (SMB) and enter the computer's IP address.

What to do if you need a password but don't remember it?

If the system prompts you for a password when connecting and you've disabled password protection, try entering the login and password of the user account logged on to the host computer. If this doesn't help, check whether password protection has been re-enabled after a Windows update. As a last resort, create a new user with a simple password specifically for network access.

Solving common access problems and errors

Even with careful configuration, errors can still occur. One of the most common is "Windows cannot access...." This is often due to older versions of the SMB protocol (such as SMBv1) being disabled in newer versions of Windows 10 and 11 for security reasons, while older devices (TVs, NAS) require them.

To enable older protocols, go to Control Panel → Programs and Features → Turn Windows features on or off. Find "SMB 1.0/CIFS File Sharing Support" in the list and enable the necessary features. However, this should only be done if absolutely necessary, as the protocol is vulnerable.

Another common issue is the "0x80070035" error. It's often resolved by editing the registry or enabling the detection service. Also, check your antivirus: third-party firewalls may block incoming connections, deeming them suspicious. Try temporarily disabling your antivirus for diagnostic purposes.

⚠️ Note: Windows settings interfaces and menu item names may vary slightly depending on your operating system version (Home, Pro, Enterprise) and installed updates. If you can't find the item you need, use the system settings search.

If the computer is visible but the folders are empty, check the access rights on the "Security" tab. It often happens that permissions are granted in "Access," but the user is blocked in "Security (NTFS). Permissions must be consistent at both levels.

Questions and Answers (FAQ)

Is it possible to access a shared folder over the internet while away from home?

Direct access to a shared folder over the internet is impossible without additional configuration. This requires port forwarding on the router (which is insecure) or using VPN technologies (such as Tailscale or the router's built-in VPN server) to trick the remote computer into thinking it's on the local network.

Why can't computers see each other even though they have the same Wi-Fi?

Most likely, one of the devices has its network profile set to "Public." In this mode, Windows hides the computer. Also, check whether client isolation is enabled on the router and whether discovery services are running on both computers.

How do I remove access to a shared folder?

Go to the folder properties, click the "Sharing" tab, click "Advanced Settings," and uncheck "Share this folder." Once the settings are applied, the folder will be accessible only to the owner.

Is it safe to disable password protection?

On a home network where there are no strangers and a strong Wi-Fi password (WPA2/WPA3) is used, this is acceptable for convenience. Disabling password protection in public places or offices is strictly not recommended, as anyone connecting to it will be able to access your files.
