Modern users often need to quickly transfer large amounts of photos, video archives, or work documents from one laptop to another. Using USB drives or external hard drives becomes inconvenient when files weigh tens of gigabytes and there's no suitable cable on hand. In such situations, a local wireless network becomes the ideal solution, enabling high-speed data transfer without the need for unnecessary cables.
There are several effective methods for implementing this process, ranging from standard operating system tools to specialized software. Each method has its own advantages depending on the file size and Windows version. Below, we'll detail how to set up data exchange so you can choose the most appropriate option for your situation.
Preparing equipment and checking the network
Before starting setup, make sure both laptops are connected to the same wireless network. This is a fundamental requirement, as the computers simply won't "see" each other in the network environment. If a router isn't nearby, you can create a virtual access point on one of the devices, turning it into a Wi-Fi server for the second laptop.
Check that the network adapter is active on both devices and that the drivers are working correctly. A Wi-Fi icon with a full signal strength should be displayed in the system tray. A weak signal can cause the connection to drop while copying large amounts of data, requiring a restart.
It's also important to ensure that antivirus software or a built-in firewall isn't blocking your computer from being detected on the network. Often, when you first connect to a new network, Windows asks you about the profile type. Be sure to select "Private" or "Home," as the "Public" profile hides your device from other network members for security reasons.
⚠️ Important: If you're in a public place (cafe, airport), make sure client isolation is enabled on your router. On such networks, file transfers between devices are usually blocked by the network administrator.
Setting up sharing in Windows 10 and 11
The standard Windows mechanism allows you to share folders for access from other computers. First, you need to enable network discovery. Open Control Panel, go to Network and Sharing Center and select Change advanced sharing settings.
In the window that opens, find the "Private" profile and ensure "Turn on network discovery" and "Turn on file and printer sharing" are enabled. At the bottom of the window, under "All Networks," we recommend enabling "Turn off password-protected sharing" if you're on a trusted home network and want easier access without entering credentials.
After changing the settings, be sure to click "Save Changes." The system is now ready to accept incoming connections. If you want to transfer a specific folder, right-click it, select "Properties," go to the "Access" tab, and click "Advanced Settings."
Check the "Share this folder" box and set the necessary permissions for the user group, such as "Allow" for "Full Control" or "Modify." This will allow the second laptop to not only read files but also write new data to this directory.
Finding a computer and connecting to shared resources
After setting up the first laptop (the server), move on to the second (the client). Open File Explorer and select "Network" in the left pane. If network discovery is enabled correctly, you'll see the name of the first computer in the list of available devices.
If the computer isn't visible, you can try accessing it directly using its IP address. To do this, find the IP address of the first laptop by entering the command in the command line. ipconfig and find the IPv4 address line. Then, in the address bar of the second laptop's Explorer, enter \\192.168.1.XX (where XX is the address of the first device).
If the connection is successful, a window will open with a list of all shared folders. You can copy files by dragging and dropping or using the clipboard. The transfer speed in this case will depend on the Wi-Fi router standard (802.11n, ac, or ax) and the distance between the devices.
☑️ Network setup checklist
⚠️ Note: Settings interfaces may vary slightly depending on your Windows 10 or 11 build version. Microsoft periodically updates the layout of menu items, so if you don't find an option right away, try searching in the system settings.
Using Nearby Sharing
Newer versions of Windows 10 and 11 introduce a convenient Nearby Share feature, similar to AirDrop in macOS. It lets you transfer files and links via Bluetooth and Wi-Fi Direct without the hassle of setting up shared folders. For this feature to work, Bluetooth and Wi-Fi must be enabled on both laptops.
You can enable this feature via the Start menu → Settings → System → Sharing (or Experience Sharing). Make sure the "Nearby Sharing" switch is set to "On." Also, select "Everyone Around Me" or "My Devices" to allow file transfers.
To transfer a file, simply right-click it and select the "Share" icon (or "Send"). The second laptop should appear in the list of available devices. After clicking its name, a notification will appear on the second device asking if you want to accept the file.
This method is ideal for quickly transferring small documents or a few photos. It doesn't require passwords or access rights, and works out of the box on modern systems. However, for transferring terabytes of data, it may be less stable than the classic SMB protocol.
Why isn't the second laptop visible in "Exchange Nearby"?
Nearby Sharing requires both devices to support Wi-Fi Direct and have updated Bluetooth drivers. They must also be within 10 meters (33 feet) of each other. If your devices use different Microsoft accounts, make sure your privacy settings allow sharing between all devices, not just your own.
Specialized software for high-speed transmission
If built-in Windows tools are unstable or seem too complex, you can use third-party utilities. Programs like Resilio Sync, Syncthing or Feem create their own secure network between devices, ignoring complex Windows settings.
Such programs often use P2P technology, which means data is transferred directly between laptops, bypassing the router (if the devices can see each other). This significantly speeds up the process and reduces the load on the wireless network. Simply install the app on both computers, enter the key code, or scan the QR code to pair.
The advantage of these solutions is their cross-platform compatibility: you can easily transfer a file not only to another laptop, but also to a smartphone or tablet running Android or iOS. Many of them support traffic encryption, which is important when working with confidential information.
Some utilities allow you to transfer files through a browser. For example, services like Sharedrop or Snapdrop Open a web page on both devices on the same network. You drag a file into the browser window on one laptop, and it appears for download on the other.
Comparison of data transfer methods
To help you choose the best method, we've summarized the key characteristics of each method in the table below. Pay attention to the balance between setup speed and overall performance.
| Method | Difficulty of setup | Transfer speed | Best use |
|---|---|---|---|
| Shared folders (SMB) | Average | High (up to 50 MB/s) | Regular work with large archives |
| Exchange nearby | Low | Average (depending on BT) | Quickly send documents and photos |
| Third-party software | Low | Very high | Cross-platform synchronization |
| Web services (P2P) | Minimum | Medium/High | One-time transfer without software installation |
Diagnosing problems and troubleshooting errors
The most common problem is the error "Windows cannot access..." with the code 0x80070035 or 0x80070043This is often due to a disabled SMB 1.0 service, which is disabled by default in newer versions of Windows for security reasons. You can enable it via Control Panel → Programs and Features → Turn Windows features on or off.
Another cause is an IP address conflict or a static IP address that changed after a router reboot. For stable operation, we recommend setting a static IP address for each laptop in the TCP/IPv4 protocol properties to ensure folder paths remain consistent.
If the transfer speed drops to a few kilobytes per second, check if a torrent client or update download is running in the background and clogging up the bandwidth. It's also a good idea to temporarily disable your antivirus software for a check, as it can scan every transferred byte in real time.
⚠️ Caution: Transferring system files or databases of running programs (such as Outlook or 1C) over the network can cause data corruption. Always close the programs whose files you are copying.
Questions and Answers (FAQ)
Is it possible to transfer files if one laptop is on Windows and the other is on macOS?
Yes, it's possible. On a Mac, go to System Preferences → Sharing and enable File Sharing. On Windows, enter [filename] in the address bar of File Explorer. smb://IP-address-MacYou will be asked to enter your Mac account login and password.
What is the maximum transfer speed for Wi-Fi?
The theoretical speed depends on the standard: for 802.11n (Wi-Fi 4), it's up to 150-300 Mbps, while for 802.11ac (Wi-Fi 5), it's up to 800 Mbps and higher. Actual file copy speeds are typically 30-50% of the theoretical maximum due to protocol overhead.
Is it safe to transfer data over public Wi-Fi?
No, it's best not to use shared folders on public networks without additional security. Attackers can intercept your traffic. Use a VPN or specialized encrypted software (such as Resilio Sync), or transfer data through secure cloud storage.
Why can't my laptop see another laptop on the network?
Make sure both devices are on the same network profile (Private). Ensure the Discovery Resource Publishing and SSDP Discovery services are running. Also, try temporarily disabling your antivirus software.
