In the age of cloud storage and instant messaging, transferring data between devices seems trivial. However, situations often arise when the internet is unavailable or the connection speed is poor. It's at these moments that users wonder how to send files from laptop to laptop via Wi-Fi, creating a direct local connection. This solution allows for the transfer of gigabytes of information in minutes, without using up mobile data or relying on external bandwidth.
There are many scenarios where a local network becomes the only reliable option: moving to a new apartment, setting up an office, or simply wanting to copy a movie collection to a friend's device. Modern operating systems, such as Windows 10 And Windows 11, offer built-in tools for organizing such exchanges without requiring additional software. Understanding the principles of a local network opens up opportunities for fast and secure data management.
In this article, we'll take a detailed look at several proven methods for organizing data transfer. We'll cover both classic methods using shared access and more modern solutions built into the Microsoft ecosystem. You'll learn which security settings to check to prevent your data from becoming accessible to third parties and how to avoid common connection errors.
Preparing equipment and checking the network
Before you start setting up data transfer, you need to make sure that both devices are on equal connection terms. Local area network This will only work correctly if both laptops are connected to the same router. This can be a wired connection or a wireless connection via Wi-Fi, as long as the devices can see each other in the network environment.
An important step is to check the network profile type. Windows may treat new networks as public by default, hiding your computer from other devices for security reasons. You need to change this status to "Private Network" to allow discovery. To do this, go to Settings → Network & Internet → Status and select the properties of your connection.
⚠️ Warning: If you are in a public place (cafe, airport), do not change the network profile to "Private", as this will make your files visible to all visitors to the hotspot.
It's also worth making sure that the necessary detection services are enabled on both devices. Antivirus software or third-party firewalls can often block the connection, deeming it suspicious. Temporarily disabling protection or adding the local network to the exceptions will help diagnose the problem if the connection fails.
Setting up folder sharing in Windows
The classic method, which works on all versions of Windows since XP, is creating a shared folder. This method is ideal for permanent work in the office or at home, when you need to regularly share documents between workstations. The setup process requires careful attention, but the results are worth it.
First, you need to enable the sharing feature in the Network and Sharing Center. Go to Control Panel → Network and Internet → Network and Sharing Center → Change advanced sharing settingsHere you should enable network discovery and file and printer sharing for the current network profile.
After activating the features, select the folder you plan to share, right-click it, and select "Properties." In the window that opens, go to the "Access" tab and click "Sharing." From the list of users, select "Everyone" or a specific user and add them, setting the permission level to "Read" or "Read and Write."
☑️ Check access settings
To find the shared folder on the second laptop, open File Explorer and go to the "Network" section. If the computers can see each other, you'll see the first laptop's name in the list. When you try to log in, the system may ask for the username and password of the user account that has access.
Using Nearby Sharing
For Windows 10 and 11 users, there's a more modern and convenient alternative to Apple's AirDrop, called Nearby Sharing. This technology uses a combination of Bluetooth for device discovery and Wi-Fi Direct for fast data transfer, ensuring high speeds and requiring no complex setup.
You can activate this feature from the Start menu by selecting "Settings," then "System," and finding "Nearby Sharing." Make sure the switch is set to "On," and select "Everyone Around Me" if you want to see devices even from users not in your contacts.
The file transfer process is incredibly simple: simply right-click the desired file or photo, select "Share," and wait until the target laptop's name appears in the list of available devices. The receiving end will see a notification asking if they want to save the file, which, once confirmed, will instantly appear in their "Downloads" folder.
Why isn't "Nearby Exchange" working?
This feature may not work if Bluetooth is disabled on one of the devices, the drivers are out of date, or the devices are too far apart (more than 10 meters). Also, make sure both devices are signed in to the same Microsoft account or are in the same homegroup.
It's worth noting that the transfer speed via Nearby Sharing may vary depending on the supported Wi-Fi standards. If both laptops support Wi-Fi 5 or Wi-Fi 6, the speed can reach tens of megabytes per second, which is comparable to transmission via cable.
Creating a HomeGroup and Working with Network Storage
Although classic HomeGroups were discontinued in Windows 10 version 1803, the principle of organizing local storage (NAS) remains relevant. You can turn one laptop into a server, sharing an entire drive or media library. This is especially convenient for watching movies on one device that are physically stored on another.
To set up this type of access, use the advanced sharing settings. In the folder properties, on the "Security" tab, ensure that the "Everyone" user group or a specific user has read permissions. This differs from the "Access" tab, as it controls NTFS file system permissions.
| Parameter | Shared folder (SMB) | Exchange nearby | Cloud services |
|---|---|---|---|
| Speed | High (depending on the router) | Very high (Wi-Fi Direct) | Depends on the Internet |
| Complexity | Average | Low | Low |
| Internet access is needed | No | No (for first login only) | Yes |
| File size | No restrictions | No restrictions | Limited by tariff |
When working with network drives, it's important to consider your router's bandwidth. If you plan to transfer files larger than 100 GB, it's recommended to use a bandwidth 5 GHz, which ensures a stable data flow without packet loss.
Alternative methods and using FTP servers
If standard Windows tools are not suitable for some reason or cause errors, you can use third-party solutions. One of the most effective methods is to deploy a temporary FTP servers on one of the laptops. This gives you full control over the transferred data and access to the file system.
There are lightweight portable programs such as FileZilla Server Or even the built-in capabilities of some file managers, which allow you to launch the server with one click. Once the server is running, the IP address will be displayed on the screen, which you should enter into the address bar of File Explorer on the second laptop.
Another option is to use the command line to create a temporary HTTP endpoint. For example, if you have Python installed, the command python -m http.server will launch a simple web server in the current folder. This can be useful for IT professionals who need to quickly transfer configuration files or scripts.
⚠️ Warning: When using a third-party FTP server, make sure port 21 (or another port of your choice) is open in your firewall, otherwise the connection will be reset.
The advantage of these methods is their versatility: they are independent of the Windows version and can even work between different operating systems, as long as the corresponding client is installed on the second device.
Diagnosing problems and troubleshooting connection errors
Despite the simplicity of setup, users often encounter a situation where computers can't see each other. The most common cause is different subnets. Make sure the IP addresses of both laptops start with the same name, for example, 192.168.1.X, where X is a unique number for each device.
If computer names are displayed but access is denied, try accessing the device by IP address instead of name. Enter the following in the address bar of File Explorer: \\192.168.1.15 (substituting the actual IP address of the target laptop). This allows you to bypass NetBIOS name resolution issues.
It's also worth checking the "Function Discovery Resource Publishing" service. It should be running and running automatically. You can find it using the command services.msc, launched through the Run menu.
Frequently Asked Questions (FAQ)
Is it possible to transfer files if one laptop is on Windows and the other is on macOS?
Yes, this is possible. On a Mac, go to System Preferences → Sharing and enable File Sharing. Then, in Windows, click Add Network Drive in File Explorer and enter the Mac's address. You'll need to enter your Mac username and password.
What is the maximum Wi-Fi transfer speed between laptops?
Speed depends on the Wi-Fi router standard. For the 802.11n standard, the actual speed will be around 20-40 Mbps. For 802.11ac (Wi-Fi 5), the speed can reach 80-100 Mbps, and for Wi-Fi 6, it's even higher. This is significantly faster than Bluetooth, but slower than USB 3.0.
Do you need internet to transfer files over a local network?
No, internet access is not required. Both laptops need to be connected to the same router, even if the router doesn't have a global network connection. Data is transferred directly between the devices via the local network.
Is it safe to share personal photos through a shared folder?
The transfer is safe if you're on a trusted home network. However, after the transfer is complete, it's recommended to disable folder sharing or change the permissions to prevent the data from being accessible to other devices on the network.
