Modern users often need to quickly transfer photos, documents, or large video archives between devices located in the same apartment or office. Using USB drives or cloud services isn't always convenient: flash drives tend to get lost, and cloud upload speeds are limited by your provider's plan. Fortunately, the operating system Windows 11 offers powerful built-in tools that allow you to organize a local network and transfer data at the maximum speed of your router.
A local Wi-Fi network isn't just about file sharing; it also makes managing your home media content easy. You can start a movie on your computer and instantly view it on your TV, or transfer a report from your laptop to your desktop without the hassle of wires. Local data transfer It doesn't consume internet traffic and works even without a global network connection, as long as the devices can see each other.
In this article, we will examine all the current methods of organizing communication between computers running Windows 11We'll cover both classic methods via the "Shared Folder" and modern features like "Nearby Sharing," as well as advanced command-line utilities that experienced users will appreciate.
Preparing the network and checking connection parameters
Before setting up access rights and creating shared resources, you need to ensure that both computers have equal visibility. The foundation of any local network is a proper network profile. If your system considers the current connection "Public," it will automatically hide the computer from other devices for security purposes, making it undetectable in the network environment.
To edit your profile, go to Settings → Network and Internet → Wi-Fi (or Ethernet). Click on the properties of your current connection and select the "Private" network type. This will make your computer visible to other devices and open the ports needed for file sharing. Without this step, all further settings may be useless.
It's also worth making sure both devices are connected to the same wireless network. Sometimes users accidentally connect to a router's guest network or use a mobile hotspot on one device, which disrupts the logical connection between the computers. Check the network name (SSID) on both computers—they should match exactly.
⚠️ Warning: If you're on a corporate network or in a public place (cafe, airport), switching your profile to "Private" may make your computer vulnerable to attacks from within the local network. In such cases, use only encrypted archives or temporary cloud storage.
Additionally, check that network discovery is enabled. In the Network and Sharing Center, ensure that network discovery and file sharing are enabled. These are basic settings that Windows 11 often prompts you to enable automatically when you switch profiles, but it's always a good idea to double-check.
Setting up shared access to a folder via Explorer
The classic and most reliable way to transfer files is to create a shared folder. This method is ideal for regularly working with large amounts of data, when you need files to be available at all times. To share a directory, select the desired folder, right-click, and go to Properties → Access → Advanced settings.
In the window that opens, check the box next to "Share this folder." You can also configure permission levels here: you can allow all network users to read files only or grant them full permissions to modify and delete files. For a home network, "Read/Write" permissions for the "Everyone" group or a specific user are usually sufficient.
☑️ Checking folder settings
Once the settings are applied, the folder will be accessible to other computers. To access it, open File Explorer on the second PC, go to the "Network" section, and find the name of the first computer. If the system requires a password, use the username and password of the user account logged in on the source computer.
Sometimes automatic detection doesn't work right away. In this case, you can use the direct route. Click Win + R and enter the address in the format \\ComputerName or \\192.168.1.XXThis will bypass any potential discovery service errors and immediately get you into the list of shared resources.
Using Nearby Sharing
For one-time file, photo, or link transfers, Windows 11 offers a more modern AirDrop alternative called Nearby Share. This feature uses a combination of Bluetooth for discovery and Wi-Fi Direct for fast data transfer, making the process as simple as possible. You don't need to know IP addresses or create shared folders.
To activate the feature, open Settings → System → Nearby SharingMake sure the toggle is enabled and choose who can see your computer: "Only my devices" (requires signing in to a single Microsoft account) or "Everyone." The latter option is convenient if you need to quickly transfer a file to a guest.
The transfer process is intuitive: simply right-click the file, select the "Share" icon (or "Send"), and choose a device from the list. A notification will appear on the receiving computer asking if you want to save the file. Transfer speed is limited only by the power of your Wi-Fi module and typically ranges from 10 to 30 MB/s.
It's important to note that "Nearby Sharing" is best suited for medium-sized files. When transferring archives tens of gigabytes in size, the connection may be less stable than when using a static shared folder due to the specifics of the discovery protocol.
Advanced FTP and command line sharing
For users who prefer control over the process and dislike the limitations of the File Explorer interface, the built-in Windows 11 FTP server or Python for quickly setting up an HTTP server are excellent solutions. However, the fastest way for IT professionals remains the command line and a utility. robocopy or creating a simple server.
Let's consider the Python option, as it's often installed by developers and allows you to share the current directory in seconds. Open a terminal in the desired folder and enter the command:
python -m http.server 8000Once you run this command, any other computer on the network will be able to open this folder by entering the address in the browser. http://host-ip-address:8000This is a universal method that works not only with Windows, but also with Android, iOS, or Linux devices without installing additional software.
| Method | Speed | Complexity | Best use |
|---|---|---|---|
| Shared folder (SMB) | High | Average | Constant work with documents |
| Exchange nearby | Average | Low | Fast photo/file transfer |
| Python HTTP Server | High | High | Cross-platform transfer |
| Bluetooth (without Wi-Fi) | Very low | Low | Text files, contacts |
Using the command line offers flexibility, but requires basic knowledge of network addresses. You can easily change ports and directories, which is impossible in the standard Nearby Sharing interface.
Solving visibility and access issues
Despite the simplicity of the settings, users often encounter the problem that computers cannot see each other. One of the most common causes is Windows services. Make sure the service Publishing discovery resources (Function Discovery Resource Publication) is enabled and running automatically. Without it, the computer will not be visible in the network neighborhood.
Another common issue is blocking access by antivirus or firewall software. If you're confident your network is secure, try temporarily disabling your third-party antivirus or adding a rule to Windows Firewall for your private network to allow incoming connections for File and Printer Sharing.
⚠️ Note: Windows 11 settings interfaces are constantly being updated. The layout of menu items may vary slightly depending on the build version (21H2, 22H2, 23H2). If you don't see an item, search for keywords in Settings.
It's also worth checking your Wi-Fi adapter drivers. Outdated drivers may not work correctly with the detection protocols of newer versions of Windows. Updating drivers through Device Manager or the laptop manufacturer's website often resolves connection issues.
Optimizing data transfer speed
The speed of file copying over a network directly depends on the Wi-Fi standard supported by your router and adapters. If you're using an older standard 802.11n (Wi-Fi 4) at 2.4 GHz, the speed is unlikely to exceed 3-4 MB/s. For comfortable operation, a 5 GHz connection and support for standards is required. Wi-Fi 5 (ac) or Wi-Fi 6 (ax).
Router placement is also critical. Walls, especially load-bearing ones, and household appliances create interference. For maximum speed when transferring gigabyte files, try to have both computers within line of sight of the router or in the same room. Using Wi-Fi repeaters (signal boosters) often reduces the actual data transfer speed by half.
Why does speed decrease over time?
When transferring a large number of small files over a long period of time, speed may decrease due to the specifics of the SMB protocol and the CPU load associated with processing each file's metadata. For thousands of small files, it's more efficient to first compress them into a single ZIP archive.
If your wireless connection is unstable, consider using Powerline adapters, which transmit the network through electrical wiring, or running a temporary Ethernet cable. A wired connection will always ensure stability and the full speed of your network interface.
Security when exchanging data on a local network
Open file access is convenient, but it also poses a potential security risk. Never leave shared folders open to the "Everyone" group with write access if you're on a network with untrusted users (such as in a dorm or coworking space). An attacker could not only steal data but also write a malicious file.
The best practice is to create a separate local user for network access. Create an account with a simple password, grant it permissions only to specific folders, and use these credentials when connecting from other devices. This will isolate your personal files from accidental access.
Regularly check the list of connected devices on your router. If you see an unfamiliar device actively consuming bandwidth or attempting to scan ports, immediately change your Wi-Fi password and update your Windows account passwords.
Why can't my computer see another computer on the network?
Most often, the problem lies in the "Public" network profile or a disabled discovery service. Also, make sure computer names are unique and don't contain Cyrillic characters, which sometimes cause conflicts in older versions of the SMB protocol.
How to transfer a file larger than 4 GB?
The FAT32 file system, often used on flash drives, doesn't support files larger than 4 GB. However, when transferring over a network (SMB), this limitation doesn't apply, as files are copied directly to the receiving computer's drive. Make sure the destination drive has sufficient free space.
Is it possible to share files between Windows 10 and Windows 11?
Yes, absolutely. The SMB protocols used in Windows 10 and 11 are fully compatible. The Nearby Sharing feature also works between these OS versions, as long as Windows 10 has the latest updates installed.
Is it safe to use a shared folder with a password?
Using password protection significantly improves security. When connecting to a shared folder, the system will prompt you for the remote computer's username and password. This prevents anonymous access to your data, even within the local network.
