Modern workflows often require the rapid exchange of information between devices located in the same space. USB drives are becoming a thing of the past, giving way to more technologically advanced solutions built directly into the operating system. Wireless data transfer eliminates physical limitations and the need for additional cables.
There are several proven methods for implementing this task, each with its own advantages depending on the volume of information and frequency of use. Standard Windows functionality provides powerful tools for creating a local network without requiring complex third-party software. However, for one-time operations, specialized utilities may be more convenient.
In this article, we'll detail sharing setup algorithms, explore security nuances, and analyze transfer speeds in various use cases. You'll learn how to properly configure access rights and avoid common connection errors. This guide will help you establish stable file sharing between any PC on your network.
Preparing equipment and checking network settings
Before beginning the data transfer process, ensure both computers are on the same local network. This means they must be connected to the same router, either via cable or Wi-Fi. If the devices see each other in the list of available networks, you can proceed to the next configuration step.
It's crucial to check the network type in your operating system. Windows may assign new connections the "Public" profile by default, which prevents your device from being visible to other users for security reasons. You need to change this setting to "Private" or "Home" to allow discovery.
To complete this procedure, open your network settings and locate your active connection. In the network profile properties, select the option to allow discovery. Without this step, computers will ignore connection requests, even if the Wi-Fi password is entered correctly.
⚠️ Warning: If you're on a private network (like a cafe or airport), changing your profile to "Private" may make your files accessible to others. Use this method only on trusted home or office networks.
It's also worth paying attention to the workgroup name. By default, Windows uses the name WORKGROUP, and it must be identical on all computers participating in the data exchange. Changing the workgroup name requires a system reboot for the changes to take effect.
Setting up folder sharing in Windows
The primary file transfer mechanism is SMB (Server Message Block) technology, which allows you to share specific directories over the network. To activate this feature, you must select the folder you plan to use as the sharing storage.
Right-click the selected folder and go to Properties. The "Sharing" tab contains the "Advanced Settings" button, where you should check the "Share" box. You can also limit the number of simultaneous users here, although this is rarely relevant for a home network.
The next step is to set access rights. Click the "Permissions" button and ensure that the "Everyone" group or a specific user has "Read" or "Modify" rights. "Modify" rights allow not only downloading files but also uploading new ones or deleting old ones.
It's also important to check your sharing settings in the Network and Sharing Center. Go to Control Panel → Network and Internet → Network and Sharing Center → Change advanced sharing settingsNetwork discovery and file and printer sharing should be enabled here.
☑️ Checking sharing settings
If you want to simplify access and avoid entering a password each time, in the same advanced settings, find the "All Networks" section and select "Turn off password-protected sharing." This will reduce the security level but significantly speed up the connection process.
Using Nearby Sharing
Newer versions of the Windows 10 and 11 operating systems feature a feature called "Nearby Sharing," which works similarly to AirDrop in the Apple ecosystem. This method uses a combination of Bluetooth for discovery and Wi-Fi Direct for fast file transfers, making it very convenient for one-time operations.
To activate this feature, go to System Preferences and find "System," then "Sharing." Make sure the "Nearby Sharing" switch is set to "On." Also, make sure Bluetooth is enabled on both devices, as it's used for the initial handshake.
The transfer process is as follows: you select a file, click the "Share" button in the context menu or through the app bar, and the system begins searching for available devices within range. A notification will appear on the receiving computer asking if you want to save the file.
⚠️ Note: Transfer speeds via Nearby Sharing may vary depending on your Bluetooth version and Wi-Fi Direct support. For files larger than 2 GB, this method may be less efficient than creating a shared folder.
A unique feature of this method is its ephemeral nature: it doesn't require constant network configuration or port forwarding. However, both computers must have their lock screen enabled or be awake, otherwise the connection may fail. This is an excellent option for quickly transferring photos or documents.
What should I do if devices don't see each other in Nearby Sharing?
Make sure Bluetooth is enabled on both PCs and they are within 10 meters of each other. Also, make sure the device's discoverability is enabled in the privacy settings. Sometimes restarting the Bluetooth service in Task Manager or simply toggling Airplane Mode on and off can help.
Transferring data via third-party utilities and cloud services
When built-in Windows tools present challenges or cross-platform solutions are required (for example, transferring between Windows and macOS/Linux), third-party programs come to the rescue. The leader in this niche is the utility Resilio Sync (formerly known as BitTorrent Sync), which operates on the P2P protocol.
The advantage of such programs is that they eliminate the need for complex network permissions and port forwarding on the router. Simply install the app on both computers, enter the sync key or scan the QR code, and the folders will automatically sync over the local network.
Another popular option is to use cloud storage with local synchronization function, such as Dropbox, Google Drive or Yandex.DiskWhen installing the desktop client, these programs create a special folder, the contents of which are instantly copied to other devices logged in under the same account.
A comparison of data transfer methods is presented in the table below so you can choose the best one for your situation:
| Method | Speed | Difficulty of setup | Security |
|---|---|---|---|
| Shared folder (SMB) | High (depending on the router) | Average | High (with password) |
| Exchange nearby | Average | Low | Average |
| Third-party utilities | High | Low | Depends on the software |
| Cloud services | Depends on the Internet | Low | High |
The choice of a specific tool depends on your priorities: speed, convenience, or independence from the internet connection. For regular work with large volumes of data, local synchronization via SMB or Resilio Sync will be the most productive solution.
Troubleshooting visibility and connection speed issues
Even with proper configuration, users may encounter a situation where computers cannot see each other in the network environment. The problem often stems from Windows services that are disabled by default. Specifically, these are the "Function Discovery Resource Publishing" and "Discovery Provider Host" services.
To activate them, click Win + R, enter services.msc and find the specified services in the list. Set the startup type to "Automatic" and start them. This often resolves the issue of computers disappearing from the list of network devices.
Another common cause of slow transfer speeds is using an outdated Wi-Fi standard. If your router supports Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax)If your computer is connected via the 2.4 GHz band, the speed will be limited to 40-50 Mbps. It's recommended to use the 5 GHz band for transferring large files.
⚠️ Note: Router and operating system interfaces are constantly updated. Switch locations and menu item names may differ from those described depending on the firmware version of your equipment. Always consult the manufacturer's official documentation if you cannot find the setting you need.
It's also worth checking your antivirus software. Third-party firewalls may block incoming SMB connections, considering them potentially dangerous. Try temporarily disabling protection or adding an exception rule for your local subnet.
Security when transmitting data over a wireless network
Transmitting confidential information over wireless channels always carries certain risks. Even on a home network, an attacker with access to the Wi-Fi network could theoretically attempt to intercept data packets. Therefore, using WPA2 or WPA3 encryption is a mandatory minimum.
When setting up shared folders, always try to use accounts with passwords. Disabling password protection, while convenient, allows access to your files to any device that can connect to your network. If you frequently host guests, create a guest Wi-Fi network for them, isolated from the main computers.
Regularly update your operating system and network drivers. Updates often contain security patches that address vulnerabilities in SMB protocols, which are actively exploited by ransomware. Ignoring updates can lead to the compromise of your entire home network.
For particularly sensitive data, consider using encrypted archivers before sending. Creating a password-protected archive will add an extra layer of protection, even if the file is intercepted during transmission. This is a simple but effective precaution.
Is it possible to transfer files if the computers are in different cities?
Yes, this is possible, but not via a local Wi-Fi network. Transferring data between remote computers requires an internet connection. Optimal solutions include cloud storage (Google Drive, Yandex.Disk), an FTP server with a static IP address, or specialized remote access programs like TeamViewer, AnyDesk, or Resilio Sync running in internet mode.
Why is my Wi-Fi speed so much lower than my router's advertised speed?
Actual speed is always lower than theoretical due to protocol overhead, signal strength, interference from neighboring networks, and the characteristics of the receiving device's network card. Furthermore, the speed is split between all connected clients. When transferring large files over 5 GHz Wi-Fi, actual speeds rarely exceed 300-400 Mbps, even on high-end routers.
Do I need to install the same version of Windows on both computers?
No, the operating system version is not critical. Windows 10 and Windows 11, as well as older versions (7, 8.1), can successfully exchange data via the SMB protocol if the correct protocol versions (SMBv2 or SMBv3) are configured and the workgroup names match.
