Every user faces the need to urgently transfer documents, photos, or large folders from one device to another. If you don't have a flash drive or external hard drive handy, and your internet connection isn't stable enough for cloud services, a local wireless network can be a lifesaver. Local Wi-Fi network Allows you to organize high-speed data exchange between devices located in the same room or office without using unnecessary wires.
Modern operating systems such as Windows 10 And Windows 11, offer built-in file sharing tools that are often underutilized. Understanding how sharing works and properly configuring network profiles will save you from having to search for third-party software. In this article, we'll explore proven methods that guarantee fast and secure data transfer.
The main advantage of this method is that the transfer speed is limited only by the capabilities of your router and network adapters, not by your provider's rates. You don't waste mobile data or rely on cloud storage server upload speeds. This is especially important when working with gigabytes of video archives or system backups.
Checking network settings and preparing equipment
Before transferring data, ensure both laptops are in the correct network environment. A basic requirement is that both devices are connected to the same Wi-Fi access point. If you're using a smartphone as a modem, ensure both laptops are connected to its network and not to different router frequencies if they have isolated clients.
A critical step is choosing a network profile. Windows may consider a new network "Public" by default, which prevents the device from being visible to others. You need to change the profile to "Private" to enable discovery. You can do this by going to Settings → Network and Internet → Wi-Fi and selecting the name of your network.
⚠️ Attention: Switching your network profile to "Private" makes your laptop visible to other devices in cafes or airports. Always switch your profile back to "Public" when connecting to unknown Wi-Fi networks outside your home.
It's also worth checking that network discovery is enabled. In Control Panel, under "Network and Sharing Center," you need to enable the "Turn on network discovery" option. Without this step, the laptops simply won't "see" each other, even if they're on the same network. To access advanced settings, use the command control in the Run window (Win+R).
Setting up a shared folder for access over a local network
The most classic and reliable method of sharing is creating a shared folder. This method doesn't require installing any additional software and operates at the SMB protocol level. First, create a new folder in any convenient location, such as on a disk. C: or D:, and give it a descriptive name, such as "Exchange".
Next, you need to configure access permissions. Right-click the folder, select "Properties," and go to the "Sharing" tab. Click "Advanced" and check "Share this folder." In the "Permissions" section, make sure the "Everyone" group has "Full Control" permission, or at least "Change" if you plan to not only read but also write files.
☑️ Checking shared folder settings
It is also important to configure the sharing settings in the system. Follow the path Control Panel → Network and Internet → Network and Sharing Center → Change advanced sharing settingsIn the "Private (Current Profile)" section, make sure "Turn on network discovery" and "Turn on file and printer sharing" are enabled. It's also recommended to disable password protection if you completely trust the devices on your network. This will make it easier to connect without entering credentials.
Once configured on the receiving laptop, open File Explorer and find "Network" in the left pane. If the settings are correct, you'll see the name of the first laptop. When you open it, you'll find the shared folder. For convenience, you can right-click the folder and select "Map as network drive" to make it appear as a separate drive in "My Computer."
Using Nearby Share in Windows 10 and 11
For users of modern versions of Windows, a simpler alternative is available: Nearby Sharing. It works similarly to AirDrop in the Apple ecosystem and allows you to transfer files directly via Wi-Fi Direct and Bluetooth, bypassing the complex setup of shared folders. It's ideal for one-time transfers of documents or photos.
To activate the feature, open Settings → System → General Features (in Windows 10) or Settings → System → Nearby sharing (in Windows 11). Make sure the toggle is on and select "Everyone" or "My devices." Make sure Bluetooth and Wi-Fi are enabled on both laptops, as the technology uses a combination of these two for searching and sharing.
The transfer process is extremely simple: simply right-click the file you want to send and select "Share" from the menu. In the window that opens, the system will begin searching for nearby devices. Once the second laptop's name appears, click it. A notification will pop up on the receiving end asking them to confirm receipt of the file.
Why isn't "Nearby Exchange" working?
This feature may not work if the devices are too far apart (optimally up to 10 meters), if Bluetooth is disabled on one of them, or if a firewall is blocking the connection. It also doesn't work between different Microsoft accounts if "Just My Devices" mode is selected.
Transfer speeds via Nearby Sharing may vary depending on file size and airborne interference. For small documents, this method is preferable due to its simplicity. However, for transferring hundreds of gigabytes of data, the shared folder method is better, as it provides a more stable connection and allows for resume of interrupted transfers.
Transferring data using the command line and PowerShell
For advanced users who prefer more control over the process, command-line tools are available. While the graphical interface is convenient, knowing the commands allows you to quickly diagnose connection issues. For example, you can check the availability of a second laptop using the ping utility. Open the command prompt (cmd) and enter the IP address of the target device.
If you need to quickly copy a file, knowing the IP address of the remote machine, you can use the UNC path directly in File Explorer or through the console. In the File Explorer address bar, enter \\192.168.1.XX (where XX is the address of the second laptop). This will instantly open access to shared resources, bypassing the network environment search step.
IN PowerShell You can use cmdlet Copy-Item to automate the process, although for one-time operations this may be overkill. The command will look something like this:
Copy-Item -Path "C:\Docs\file.txt" -Destination "\\Laptop2\Share\"Using IP addresses instead of computer names often helps solve name resolution problems on a local network when a laptop is not visible by name but can be pinged by its numerical address.
Alternative methods: FTP server and cloud buffers
If the built-in Windows tools seem too cumbersome or unstable, you can deploy a lightweight FTP server on one of your laptops. Programs like FileZilla Server or even the built-in capabilities of IIS allow you to turn a folder into an FTP resource. The second laptop connects to it as a network drive by entering the address ftp://192.168.1.XX.
Another option is to use "cloud buffers". Services like Telegram (section "Favorites"), Discord or specialized P2P utilities like Resilio Sync Allows you to transfer files over the internet, but using a local connection if the devices are on the same network. However, this often requires access to the global network for authentication, which can be slower than direct transfers.
| Method of transmission | Difficulty of setup | Transfer speed | Best use |
|---|---|---|---|
| Shared folder (SMB) | Average | High (depending on the router) | Regular work with large volumes of data |
| Nearby Exchange | Low | Average | Quick transfer of photos and documents |
| FTP server | High | Very high | Professional work, automation |
| External storage | Low | Maximum (USB 3.0) | Transferring terabytes of data without a network |
The choice of method depends on your specific needs. For home use, "Nearby Sharing" is often the fastest, right-now solution. For office work or continuous data backup between machines, it's better to set up a shared folder once and forget about visibility issues.
Diagnosing problems and troubleshooting connection errors
Despite the simplicity of the technology, users often encounter access errors. One of the most common problems is the error 0x80070035 ("Network path not found"). This is often caused by a disabled SMB 1.0 service (although it is best not to enable it for security reasons) or problems with the TCP/IP protocol.
Try resetting your network settings. In Windows 10/11, this can be done via Settings → Network & Internet → Advanced network settings → Network resetAfter rebooting, the system will reinstall network drivers and reset protocol settings, which often resolves mysterious visibility issues.
⚠️ Attention: Antivirus programs and third-party firewalls (Kaspersky, ESET, Avast) may block incoming connections on your local network. If all else fails, try temporarily disabling network protection in your antivirus or adding your subnet (e.g., 192.168.1.0/24) to the trusted list.
Also check if the Connect Now Discovery Resource Publishing and Discovery Provider Host services are disabled. You can find them by entering the command services.msc in the Run window. Make sure they are running and the startup type is set to Automatic. Without these services, the Windows detection mechanism will not work.
If you use routers with the "AP Isolation" feature, devices on the Wi-Fi network will not be able to see each other. This feature is often enabled on guest networks at hotels or cafes. On your home router, you need to find this option in the Wireless Settings and disable it to allow communication between clients.
Frequently Asked Questions (FAQ)
Is it possible to transfer files if one laptop has Windows and the other has macOS?
Yes, it's possible. On a Mac, go to System Preferences → General → Sharing and enable "File Sharing." Then, on Windows, enter [filename] in the File Explorer address bar. \\IP-address-MacYou will be asked to enter your Mac account login and password.
What is the maximum transfer speed over Wi-Fi?
Speed depends on the Wi-Fi standard. At 2.4 GHz, actual speeds rarely exceed 4-6 MB/s. At 5 GHz (AC/AX standards), speeds can reach 50-100 MB/s and higher, comparable to fast flash drives, but still slower than a USB 3.0 cable.
Is it safe to transfer files through a shared folder?
On a home network, yes. On public Wi-Fi networks, it's risky. For security, always use strong passwords for your accounts and don't disable password protection when using untrusted networks.
Why does file transfer get interrupted in the middle?
This is most often due to an unstable Wi-Fi signal, the laptop going into sleep mode, or being blocked by an antivirus program. Make sure your power plan prevents the adapter from being turned off to save power.
