In the age of ubiquitous digital content, the issue of quickly transferring large files between devices is more pressing than ever. Good old flash drives are often lost, and external hard drives require a physical connection, which is not always convenient, especially if the computers are in different rooms. That's why technology local wireless network remains one of the most effective solutions for exchanging data within the home or office.
Modern Wi-Fi standards enable speeds comparable to wired connections, making copying gigabytes of photos, video archives, or work documents virtually instantaneous. You no longer need to fumble around with storage drives or search for a free USB port. The key is understanding the basic principles of network setup and knowing the tools your operating system offers.
In this article, we'll explore proven methods that work on current versions of operating systems. We'll cover both built-in Windows features and third-party utilities that can make your life significantly easier. Whether you need to transfer a single document or create a complete system backup, you'll find a suitable method.
Preparing equipment and checking the network
Before setting up a complex network connection, you need to ensure your infrastructure is ready for data transfer. A stable connection is the foundation of any wireless communication. Both computers must be connected to the same access point. Wi-Fi routerIf one device is on a guest network and another is on the main network, they may not be able to "see" each other due to client isolation.
It's also important to check the frequency range your network operates on. Modern routers often broadcast two frequencies: 2.4 GHz and 5 GHz. For transferring large files, it's preferable to use the 2.4 GHz and 5 GHz bands. 5 GHz, as it provides higher throughput and is less susceptible to interference from household appliances. However, if devices are located far from the router, the 2.4 GHz band may be more stable, albeit slower.
⚠️ Please note: Some corporate networks or public hotspots (cafes, airports) have built-in security that blocks direct connections between user devices. Under these conditions, standard file transfer methods will not work.
Make sure the network adapter is activated on both computers and the drivers are installed correctly. There shouldn't be any warning signs in Device Manager. It's also worth checking that the network type in Windows is set to "Private" and not "Public," as this directly affects the computer's visibility to other network members.
Method 1: Using a shared folder (SMB protocol)
The most classic and reliable method, built directly into the Windows operating system, is creating a shared network folder. This method does not require installing additional software and is based on the protocol SMB (Server Message Block)It is ideal for regularly exchanging files between desktop computers in the office or at home.
First, select the folder on the sending computer you plan to share. Right-click it and select "Properties." Go to the "Sharing" tab and click "Advanced." Check "Share this folder" and click "Permissions."
It's important to configure the permissions correctly in the permissions window. If you're on a trusted home network, you can grant the "Everyone" group "Read" and "Modify" permissions. This will allow the second computer to not only retrieve files but also write their own. After applying the settings, the system will display the network path to the folder, which looks like this: \\COMPUTER_NAME\FOLDER.
On the receiving computer, open Explorer, enter the IP address of the first computer in the address bar (you can find it using the command ipconfig (in the command line) or its network name. If the system prompts you for credentials, enter the username and password of the user on the first computer. This is required for authorization, even if you are on the same network.
Method 2: Nearby Sharing
For Windows 10 and 11 users, there's a more modern and convenient alternative to complex sharing settings: Nearby Share. This mechanism uses a combination of Bluetooth for device discovery and Wi-Fi Direct for fast data transfer. It works similarly to AirDrop in the Apple ecosystem, allowing you to send files with a single click.
To activate this feature, open Settings (keys Win + I), go to the "System" section and find "Nearby Sharing." Make sure the toggle is turned on. In the visibility settings, select "Everyone around me" or "My devices" if both computers use the same Microsoft account. This will ensure maximum security and convenience.
The transfer process is extremely simple: simply right-click the file, select "Share," and see the neighboring computer's name in the list of available devices. A pop-up notification will appear on the receiving end, asking if they want to save the file. The speed is limited only by the power of your Wi-Fi module and can reach tens of megabytes per second.
⚠️ Note: Nearby Share requires Bluetooth and Wi-Fi to be enabled on both devices. Both computers must also support Wi-Fi Direct for the transfer protocol to work correctly.
The main advantage of this method is that there's no need to configure access rights, user passwords, or network drives. The system automatically detects devices, checks their compatibility, and establishes a secure connection. However, for transferring thousands of small files, this method may be less efficient than creating a shared folder due to the overhead of establishing a connection for each file.

Comparison of data transfer methods
The optimal method depends on your specific needs, data volume, and technical expertise. Below is a comparison table to help you choose the method that best suits your needs.
| Method | Transfer speed | Difficulty of setup | Best use |
|---|---|---|---|
| Shared folder (SMB) | High (up to 50+ MB/s) | Average | Regular work with large archives |
| Exchange with the environment | Medium/High | Low | Fast transfer of individual files |
| Third-party software (FTP) | Maximum | High | Professional work with servers |
| Cloud services | Depends on the Internet | Low | Transfer between different |
As the table shows, Windows' built-in tools offer an excellent balance between speed and convenience. For most home users, Nearby Share will be more than sufficient. However, if you need to provide constant access to your media library on a media player or another PC, creating network folder will become a more rational solution.
Why is Wi-Fi speed slower than cable?
Wireless signals are subject to attenuation, reflections from walls, and interference from other devices. Furthermore, the Wi-Fi protocol operates in half-duplex mode, meaning a device cannot simultaneously receive and transmit data on the same frequency, which theoretically reduces the actual channel throughput by half compared to gigabit Ethernet.
Using specialized software and FTP
If the standard Windows tools seem cumbersome or unstable, third-party programs can help. One of the most powerful tools is creating your own FTP serversPrograms like FileZilla Server or the built-in IIS server allow you to turn any computer into a file storage device with flexible access rights and logging.
Another popular option is synchronization utilities like Resilio Sync or Syncthing. They create a decentralized network between your devices. You simply specify a folder on one PC, and the program automatically finds a second computer on the Wi-Fi network and begins synchronizing changes. This is ideal for those managing projects across multiple machines.
There are also lightweight, one-time transfer programs that work through a browser, such as Sharedrop or Snapdrop. They use WebRTC technology to transfer files directly between the browsers of two computers on the same network. You don't need to install anything: just open the website on both computers, drag the file into the browser window, and scan the QR code or enter the session code.
⚠️ Caution: When using third-party software, especially free ones, carefully monitor your firewall settings. Antivirus software may block incoming connections, deeming them suspicious, which will result in transmission errors.
For advanced users working with Linux or macOS in conjunction with Windows, SFTP is an excellent solution. It provides encryption of transmitted data, which is critical if you're transferring sensitive documents over your network. Setting it up requires knowledge of the command line, but the results are worth it.
Speed optimization and troubleshooting
Even with proper setup, you may experience slow transfer speeds. Often, the bottleneck isn't the Wi-Fi technology itself, but rather the hardware configuration or interference. Make sure your router supports the standard. 802.11ac (Wi-Fi 5) or newer 802.11ax (Wi-Fi 6)Older 802.11n devices are physically incapable of transmitting data faster than 40-50 Mbps in real-world conditions.
If your speed is dropping, try changing the wireless channel in your router settings. In apartment buildings, the airwaves can be clogged with signals from neighboring networks, causing collisions and retransmissions of data packets. Using Wi-Fi analyzers on your smartphone can help you find the least congested channel and switch to it.
It's also worth checking your network adapter's power-saving settings. In Device Manager, under your Wi-Fi adapter's properties, on the "Power Management" tab, uncheck "Allow the computer to turn off this device to save power." This will prevent short-term connection drops or signal strength reduction during active transmission.
Alternative scenarios and cloud solutions
Sometimes a direct Wi-Fi connection is impossible or impractical. For example, if the computers are located in different cities, or the local network settings are blocked by the administrator. In such cases, cloud storage comes into play. Services like Yandex.Disk, Google Drive, or OneDrive allow you to upload a file from one PC and download it on another.
Although this method depends on your internet speed, it has a huge advantage: it's independent of your local infrastructure. You don't need to know IP addresses, configure ports, or worry about device visibility. Simply log in to your account.
For very large amounts of data (hundreds of gigabytes), the cloud can be inconvenient due to traffic limits or download times. External drives are a great option here, but if you don't have one handy, you can create a temporary local network via your mobile phone (access point mode), although this will be significantly slower than using a full-fledged router.
In conclusion, choosing a data transfer method depends on your priorities: speed, security, or simplicity. Neighborhood Sharing is ideal for one-time operations, shared folders for ongoing work, and the cloud for remote access. Understanding these tools will make your data management much more efficient.
Why can't my computer see another computer on the network?
Most often, the problem lies with the network profile. If the network is marked as "Public," Windows is blocking discovery. Also, check if Network Discovery is enabled in the Network and Sharing Center and that DNS is running.
What is the maximum transfer speed on 5GHz Wi-Fi?
In real-world home environments, using the 802.11ac standard, speeds of 30-60 MB/s (megabytes per second) can be achieved. The theoretical limit is significantly higher, but this is reduced by distance, walls, and the number of connected devices.
Is it safe to share passwords through a shared folder?
Data transfer within a home network is relatively secure, but older versions of SMB don't encrypt data by default. For critical data, it's best to use password-protected archives or encrypted protocols like SFTP.
Is it possible to speed up the transfer by disabling the antivirus?
Antivirus software can scan every transferred file in real time, which reduces speed. Temporarily disabling protection while transferring large amounts of data can speed up the process, but only do this on a trusted network.
