Modern users often face the need to urgently transfer data between devices when they don't have a USB flash drive or external hard drive at hand. Transferring files via Wi-Fi It's one of the most convenient and fastest ways to solve this problem, eliminating unnecessary wires and speed loss. A local area network provides a stable connection that's significantly more efficient than Bluetooth or wired transmission via intermediate media.
There are many methods, from built-in operating system functions to third-party utilities, each of which has its own characteristics and usage scenarios. Windows 10 and Windows 11 Offer native data exchange tools that don't require additional software. However, larger data volumes or specific formats may require more advanced solutions.
In this article, we will look at the most relevant methods that will allow you exchange gigabytes of data without loss of quality and at maximum speedYou'll learn how to set up a shared folder, use Nearby Sharing, and which alternative programs are worth considering this year. Choosing the right method will save you time and frustration.
Advantages of wireless data transmission over a local area network
Using Wi-Fi to share files between laptops offers a number of undeniable advantages over traditional methods. First and foremost is speed: modern standards Wi-Fi 5 and Wi-Fi 6 Allows for transfer speeds comparable to a wired Fast Ethernet connection. This makes copying large video files or game archives fast and seamless.
Furthermore, the lack of physical contact between devices reduces the risk of damage to ports and cables. You can continue working from different rooms in the apartment as long as the router signal is sufficient. Local area network It's also safer than cloud storage, as your data doesn't leave your home or get uploaded to third-party servers.
⚠️ Note: Transfer speed directly depends on the power of your router and the distance between devices. If your router is old or located far away, speed may drop to a minimum.
It's important to note that for most methods to work, both laptops must be connected to the same network. This could be a home Wi-Fi router or a virtual access point created on one of the devices. This approach ensures that traffic is isolated from unauthorized users.
Setting up a shared folder in Windows 10 and 11
The most classic and reliable method, which doesn't require installing additional software, is creating a shared folder. This method is ideal for regularly sharing documents in the office or at home. First, make sure both computers are on the same network and have the same network type (private or home).
Go to the control panel and find the section Network and Sharing CenterHere you need to choose Change advanced sharing optionsIn the "Private" profile, enable network discovery and file and printer sharing. Without this step, the computers simply won't see each other in the device list.
☑️ Preparing to set up a shared folder
After enabling the features, find the folder you want to share, right-click it, and select "Properties." Go to the "Share" tab. Access and press the button General access..Add the "Everyone" user and grant them read and write permissions. This folder will now be visible to other devices on the network.
To find the shared folder on the second laptop, open File Explorer and go to the section NetIf the computers are not displayed, try entering the IP address of the first laptop into the address bar of the explorer in the format \\192.168.1.XYou can find out the IP address by entering the command in the command line ipconfig.
⚠️ Note: If you are prompted for a password when connecting and you haven't changed it, try entering the login and password for your Microsoft account or local administrator account on the first laptop.
Using Nearby Sharing
Starting with Windows 10, the system has a feature Nearby Sharing, which works similarly to AirDrop on Apple devices. This method is significantly easier to set up than shared folders and is ideal for quickly transferring individual files, photos, or links.
To activate, open "Settings" (keys Win + I) and go to the section System → General Features (or "Nearby Sharing"). Make sure the toggle is on and select "Everyone Around Me" or "My Devices." This will make your laptop visible to other devices within Wi-Fi range.
The transfer process is simple: select the file, right-click, and select "Share." The second laptop should appear in the list of available devices. Once the second device confirms receipt, the file will automatically be saved to the "Downloads" folder.
What should I do if Nearby Sharing doesn't detect devices?
Make sure Bluetooth and Wi-Fi are enabled on both devices. Also, check that the discovery services aren't blocked by your antivirus or firewall. Sometimes restarting the Discovery Service in Windows Services helps.
It's worth noting that this method may perform slower than a shared folder, as it uses a discovery protocol that may be less optimized for large data volumes. However, for documents and photos, this is the fastest way to transfer them "here and now."
Specialized software for fast transfer
If Windows' built-in tools seem too complex or unstable, third-party programs can help. The leading utility in this niche is LocalSend or classic ShareIt (in the PC version). They create their own direct connection between devices, bypassing complex router settings.
The advantage of such programs is their cross-platform compatibility. You can easily transfer files not only between Windows laptops but also send them to an Android smartphone or iPhone, as long as they're connected to the same Wi-Fi network. The interface typically consists of a list of devices and a "Send" button.
| Program | Platforms | Speed | Internet access is needed |
|---|---|---|---|
| LocalSend | Win, macOS, Linux, Android, iOS | High | No (LAN only) |
| ShareIt | Win, Android, iOS | Medium/High | No |
| Feem | All the main ones | High | No |
| Snapdrop | Browser (Web) | Depends on the browser | No |
The service deserves special attention Snapdrop, which requires no installation. Simply open snapdrop.net on both laptops in the browser, and they will see each other. This works via WebRTC technology and is a great temporary solution if you don't have a flash drive handy and don't want to install the software.
Transferring Large Files: Nuances and Limitations
When working with gigabytes of data (for example, backing up games or editing video), different rules come into play. Even a modern Wi-Fi network has its own bandwidth and connection stability limits. A connection interruption while transferring 50 GB of data can corrupt the archive, and the process will have to be started over.
For such tasks, it is best to use the shared folder method with the protocol SMB, as it supports resuming interrupted transfers and has lower overhead. Also, make sure both laptops have the latest Wi-Fi adapter drivers installed, as older drivers may not support high-speed modes.
⚠️ Important: When transferring files larger than 4 GB, ensure the destination drive's file system supports large files (NTFS or exFAT). FAT32 will not accept files larger than 4 GB.
If the transfer is slow, try temporarily disabling your antivirus or firewall, which can scan every transmitted packet in real time. This often becomes a bottleneck, artificially reducing the speed to 1-2 Mbps.
Troubleshooting connection issues
Users often encounter situations where laptops are physically close to each other but can't see each other. First, check if one of them is set to "Public Network." In this profile, Windows hides the computer from detection by default for security reasons.
The second common problem is different frequency ranges. If one laptop is connected to the router via 2.4 GHzIf one router is connected to the other via 5 GHz, they should still be able to see each other if the router is configured correctly (client isolation is not enabled). However, the speed in mixed mode may be lower.
It's also worth checking Windows services. Click Win + R, enter services.msc and find the services related to network discovery (Function Discovery Resource Publication, SSDP Discovery). They should be running and have the startup type set to Automatic.
If all else fails, try temporarily disabling your antivirus software. Sometimes the built-in Windows firewall or third-party security software blocks incoming connections, considering them suspicious, even if you've allowed them.
Why doesn't the laptop see the second computer on the network?
Most often, the problem lies with the network profile. If the network is marked as "Public," Windows is blocking discovery. Switch the profile to "Private" in the network settings. Also, check if the "Function Discovery Resource Publishing" service is enabled.
Is it possible to transfer files without a router?
Yes, you can create a direct connection. In Windows 10/11, you can use the Mobile Hotspot feature on one laptop and connect a second one to the created Wi-Fi hotspot. Files will be transferred directly between the adapters.
What is the maximum speed possible over Wi-Fi?
Under ideal conditions (Wi-Fi 6, close to the router), actual speeds can reach 400-800 Mbps. However, in practice, taking into account interference and distance, a stable speed of 50-150 Mbps is considered equivalent to 6-18 MB/s.
Is it safe to share passwords over a shared network?
Transferring files within your home network is relatively safe if your Wi-Fi is password-protected (WPA2/WPA3). However, it's better to transfer sensitive data (bank passwords) over secure channels (HTTPS, encrypted instant messaging apps) rather than in plain text files.
