How to transfer a folder from one computer to another via WiFi in Windows 10

In the age of cloud storage and instant messaging, physically transferring files between devices on the same local network often seems like a forgotten skill. However, when it comes to moving gigabytes of photos, project archives, or movie collections, speed local network Wi-Fi significantly outperforms most internet connections. Direct data transfer over the air eliminates the need for double uploading to the cloud and then downloading to another device, saving time and bandwidth.

operating system Windows 10 offers built-in tools for organizing such sharing without the need for third-party software. Properly configuring network settings transforms the chaotic use of USB flash drives into an elegant process, accessible in just a few clicks. In this guide, we'll cover not only the basic setup steps but also security considerations and solutions to common issues users encounter when attempting to share resources.

It's worth noting that connection stability directly depends on the signal quality of your router and the distance between the computers. If you plan to transfer terabytes of data, make sure both devices are within a strong signal range or connected via 5 GHz a range that provides sufficient bandwidth for comfortable work with heavy files.

Basic requirements and preparation of the network environment

Before you begin tackling complex sharing settings, you need to ensure that the foundation of your local network is laid correctly. Both computers must be connected to the same wireless network; using the router's guest mode often blocks devices from discovering each other for security reasons. Make sure the network type in the system is defined as Private, since the "Public" profile hides the computer from other network members by default.

The most important aspect is consistency in network names and workgroups. Although modern versions of Windows are smart enough to work with standard configurations, having the same name Workgroup On both devices, this resolves 90% of visibility issues. Also, make sure your wireless adapter drivers are updated to the latest version, as older versions may not handle discovery requests correctly.

⚠️ Please note: If you are using corporate Wi-Fi or a network with AP Isolation, file transfer between devices will be technically impossible without the intervention of a network administrator, as the router blocks direct traffic between connected devices.

• 📶 Make sure both PCs are connected to the same SSID (Wi-Fi network name).
• 🔒 Check your network profile: it should be "Private" and not "Public".
• 🔄 Update your Wi-Fi adapter drivers to the latest version from the manufacturer's website.
• ⚙️ Make sure network discovery is enabled on both computers.

Setting up sharing options in Control Panel

The central hub for managing permissions in Windows 10 is the Network and Sharing Center. This is where you activate the mechanisms that allow other computers to see your device and access selected resources. To get started, open this section via Control Panel → Network and Internet or simply by entering the appropriate query in the search.

On the left side of the window, select "Change advanced sharing settings." This will open a list of profiles where you'll need to enable several critical options. First, in the "Private (current profile)" section, you need to enable network discovery and check the box for automatic configuration of connected devices, which will allow the system to open the necessary ports in the firewall.

Next, scroll down to the "All Networks" section. This is the key setting that determines whether a password is required for access. If you're in a trusted home environment, you can enable "Password-protected sharing," but to simplify access within an apartment, it's often left disabled, although it's a bit of a hassle. reduces the level of securityThe choice depends on who else could theoretically have access to your Wi-Fi.

After making all changes, be sure to click the "Save Changes" button at the bottom of the page. The system will apply the new traffic filtering rules, and the computer will become visible to other network members. If you don't do this, any subsequent folder sharing actions will fail, as the network stack will ignore incoming requests.

The process of sharing a folder and setting access rights

Now that the network infrastructure is ready, you can move on to selecting the resource for sharing. Select the folder you want to transfer or make read/write accessible from another computer. Right-click it and select "Properties," then go to the "Access" tab.

This window offers two options: simple sharing and advanced settings. For most users, the "Sharing..." button will work, with a drop-down list where you can select a user. Everyone (Everyone) or a specific system user. Clicking "Add" will add this user to the list of those who have file access rights and allow you to assign the permission level: "Read" or "Read and Write."

For more detailed settings, such as restricting read-only access or preventing file deletion, use the "Advanced Settings" button. Here you can set limits on the number of concurrent users and fine-tune permissions for different security groups using the "Permissions" button. This is especially useful if the folder will be used by multiple people with different needs.

⚠️ Important: Granting full permissions (Read and Write) to the "Everyone" group means anyone who connects to your Wi-Fi will be able to not only copy files but also delete or modify them. Use this option only on fully trusted networks.

After setting permissions, the system may ask you to confirm changing the sharing level for the entire folder if it already contains files with different attributes. Agree to apply the settings to all nested objects to avoid situations where the folder is open but the files within it are not.

Search for a computer on the network and connect to resources

On the second computer that will receive the files, find the network share. Open File Explorer and select "Network" in the left navigation panel. If network discovery is configured correctly, you will see the name of the first computer in the list of available devices. Double-clicking on the name will open a list of all shared folders.

If the system prompts you for credentials, enter the username and password for the user account on the first computer (the one where the folder is located). In Windows 10, usernames and passwords often mismatch, causing an access error. In this case, you can create an identical account on both PCs or use the guest access feature, if it's enabled.

For ease of use, we recommend mapping the network folder as a network drive. To do this, right-click the desired folder in the shared folders window and select "Map network drive." Select an available drive letter from the list, and the folder will appear in "My Computer" as a regular local partition, making it easier to manage files.

• 💻 Open File Explorer and go to the Network section.
• 🔍 Find the source computer name in the list of devices.
• 🔑 Enter your credentials if the system asks for authorization.
• 💾 Use the "Map network drive" option for quick access.

What to do if your computer is not visible on the network?

If your computer doesn't appear in the Network section, try entering its IP address directly into the File Explorer address bar in the format \\\\192.168.1.XX. Also, make sure the Function Discovery Resource Publishing service is running in Services (services.msc).

Using an IP address for direct connection

Automatic device discovery via the SMB protocol can sometimes be unstable, especially on mixed networks or when using third-party antivirus software. In such cases, the most reliable method is a direct connection via IP addressThis method bypasses discovery services and accesses the computer's network interface directly.

First, you need to find the IP address of the computer where the shared folder is located. On this computer, open the command prompt (cmd) and enter the command ipconfigFind the "IPv4 Address" line in the section for your wireless adapter; it usually looks like 192.168.0.X or 192.168.1.X. Remember or write down these numbers.

On the receiving computer, open File Explorer and in the address bar at the top, enter the address in the following format: \\192.168.1.XX (Replace XX with the actual numbers of your address). Press Enter. If your permissions and firewall settings are correct, you'll immediately have access to shared folders, bypassing the step of searching for your computer in your network neighborhood.

⚠️ Note: IP addresses on home networks are often dynamic and can change after a router reboot. If your IP connection stops working, check your current address again or configure a static IP in your router settings.

Diagnosing and resolving typical access problems

Despite the simplicity of the concept, transferring folders over Wi-Fi in Windows 10 can encounter a number of obstacles. Most often, the problem lies in the service SMB 1.0, which is disabled by default in newer OS versions for security reasons, but is required for communication with older devices or NAS storage. You can check and enable it using "Turn Windows features on or off."

Another common cause of failures is overly aggressive Windows Firewall or third-party antivirus settings. If you're confident your network is secure, try temporarily disabling your firewall to see if it's the blocking factor. If access is restored, you'll need to add an exception rule for the File and Printer Sharing protocol.

You should also pay attention to the "Discovery Provider Host" service. If it is stopped, the computer will not be able to properly advertise itself on the network. Open the Services Manager (command services.msc), find this service and set the startup type to "Automatic", then start it.

Questions and Answers (FAQ)

Is it safe to share files in a cafe or airport?

This is strongly discouraged. On public Wi-Fi networks, your data can be intercepted, and enabling public access makes your computer vulnerable to attack. Use only trusted home networks or create a secure connection.

Why does the speed drop or stop when transferring large files?

This could be due to an unstable Wi-Fi signal, interference from other devices, or limited wireless adapter power. For larger data volumes, it's better to use an Ethernet cable or the 5 GHz band.

Is it possible to transfer a folder to a computer running Windows 7 or XP?

Yes, but additional settings may be required. In Windows 10, you need to enable SMB 1.0 protocol support, as older systems don't support new encryption standards by default.

How can I find out who is currently connected to my shared folder?

Open Computer Management (right-click This PC → Manage), and go to Shared Folders → Sessions. This will display a list of active users and their open files.
