In the age of ubiquitous digitalization, the need to quickly exchange data between devices is constant. Whether transferring a large portfolio, backing up documents, or simply sharing a family video archive, searching for a USB cable or external hard drive often takes longer than the actual copying process. This is where a local wireless network comes in handy, enabling data transfer at speeds that can exceed the capabilities of older wired interfaces.
Modern Wi-Fi standards such as Wi-Fi 5 And Wi-Fi 6, provide sufficient bandwidth for comfortable work with high-resolution multimedia content. You no longer need to fumble for a flash drive or run an Ethernet cable across the room. The key is to understand how network protocols work and which tools are best suited for your operating system.
In this guide, we'll cover all relevant methods, from built-in operating system functions to specialized software. You'll learn how to create shared folders, configure access, and select the optimal transfer method for specific tasks. Proper network configuration will eliminate the hassle of physical storage devices.
Preparing equipment and checking the network
Before you begin setup, it's crucial to ensure that both computers are on the same local network. This means they must be connected to the same router or an access point. If one device is connected via cable and the other via Wi-Fi, but both are connected to the same router, this is also considered the same network.
Check the connection status on both devices. In Windows, you can do this by opening the menu Settings → Network & InternetMake sure the network profile is set to "Private" or "Home," as "Public" mode blocks detection of other devices for security reasons. For macOS, the path will look like this: System Preferences → Network.
⚠️ Note: If you're on a corporate network or public Wi-Fi (like a cafe or airport), administrators often block file sharing between clients. In such cases, standard methods may not work without special permissions.
It's also worth paying attention to your router's frequency range. For transferring large files, it's preferable to use the range 5 GHz, as it offers higher speeds and less interference than 2.4 GHz. However, its range is shorter, so computers must be relatively close to the signal source.
- 📶 Make sure both devices can see each other in the network environment.
- 🔒 Check that your antivirus isn't blocking local connections.
- 📡 Use the 5 GHz band to speed up the process.
Using the Shared Folder feature in Windows
The most native way to transfer data in a Windows environment is to create a shared network folder. This method doesn't require any additional software and works natively within the operating system. To begin, select the folder you want to share, right-click it, and select Properties → Access → Advanced settings.
In the window that opens, check the box next to "Share this folder." You can also configure access permissions here: allow read-only access or grant full control, allowing other users to modify and delete files. Once the settings are applied, the folder will be visible in the "Network" section on the other computer.
What to do if your computer is not visible on the network?
Often, the problem lies with the discovery service. Press Win+R, enter services.msc, find "Function Discovery Resource Publishing," and launch it. Also, check if network discovery is enabled in the Network and Sharing Center.
To connect to a shared folder from another PC, open File Explorer and enter the IP address of the first computer in the address bar (for example, \\192.168.1.5) or its network name. The system may request the login and password of the user account on whose computer the folder is shared. This is a standard authentication procedure.
☑️ Setting up a shared folder
If you are transferring thousands of small files, the process may take longer due to the overhead of the SMB protocol in processing the headers of each file.
Transferring data via Nearby Sharing in Windows 10 and 11
Starting with Windows 10, Microsoft has introduced a feature Nearby Sharing (Nearby Sharing), which works similarly to Apple's AirDrop. This method uses a combination of Bluetooth for device discovery and Wi-Fi Direct for fast data transfer, making the process as simple as possible for the user.
To activate the feature, go to Settings → System → General Features (in Windows 11 this is System → nearby sharing). Make sure the toggle is on and the visibility setting is set to "Only my devices" or "Everyone around." Bluetooth must be active on both computers for this feature to work.
The transfer process is intuitive: simply select a file, click the "Share" button in the context menu or app bar, and select the target device from the list. A notification will appear on the receiving computer asking if you want to save the file. This is ideal for quickly transferring documents or a few photos.
⚠️ Please note: Nearby Sharing has file transfer size limits and may be unstable when transferring archives larger than 2-3 GB. For larger files, it's better to use a network folder.
The main advantage of this method is that it eliminates the need to configure complex network permissions or know IP addresses. However, if the Bluetooth or Wi-Fi adapter drivers are out of date, this feature may not work correctly. In this case, it is recommended to update the drivers through Device Manager or the laptop manufacturer's website.
- 🔍 Only works between devices running Windows 10/11.
- ⚡ Uses Wi-Fi Direct for high speed.
- 📂 Does not require setting up shared folders.
Sync between macOS and Windows via SMB
Mixed networks that use Apple computers and Windows PCs often face compatibility issues. However, the protocol SMB (Server Message Block), a standard for Windows, is fully supported on macOS. This allows for two-way file exchange without any hacks.
To make your Mac see your Windows shared folder, open Finder, click Command + K (or through the menu Go → Connect to server). Enter the address in the format smb://Windows IP addressThe system will prompt you for your Windows account username and password. After successful login, the folder will be mounted as a network drive.
The opposite situation, when Windows connects to a Mac, requires enabling file sharing in macOS settings. Go to System Preferences → General → Sharing and enable "File Sharing." In the settings, specify which folders to share and what permissions to grant to the "Guest" user or a specific account.
It's worth noting that transfer speeds between macOS and Windows may be slower than within a homogeneous network due to differences in network stack implementation. If you plan to regularly handle large amounts of data, ensure both devices have the latest OS updates installed.
Using cloud storage as an intermediary
While the question is about transferring over Wi-Fi, you can't ignore cloud services that use your wireless connection for syncing. Services like Google Drive, Dropbox, Yandex.Disk or OneDrive They essentially act as a buffer. You upload a file to the server, and it automatically appears on the second computer.
This method has its pros and cons. The main advantage is that there's no need to configure a local network, IP addresses, or access rights. Files are accessible even if computers are located in different cities. The disadvantage, however, is obvious: speed is limited by your internet service provider (ISP), not your router's speed, and there's a disk space limit.
For one-time transfer of large files, you can use temporary storage services such as WeTransfer or Russian equivalents. You download the file, receive a link, and open it on the second device. This is faster than setting up a network if you need to transfer something right away and the local network isn't set up.
| Method | Speed | Difficulty of setup | Do you need internet? |
|---|---|---|---|
| Shared folder (SMB) | High (up to 100 Mbps) | Average | No |
| Nearby Sharing | Medium/High | Low | No |
| Cloud services | Depends on the tariff | Low | Yes |
| FTP server | Very high | High | No |
Specialized software for file transfer
If standard tools seem cumbersome to you, there are lightweight utilities designed specifically for fast file transfer over a local network. Feem or Snapdrop (works in the browser) allows you to transfer files simply by dragging and dropping, working over local Wi-Fi.
The peculiarity of such programs is that they often use their own protocol or optimized HTTP server, which allows them to bypass some Windows limitations. For example, Snapdrop is a web analogue of AirDrop: you open a website on both computers, see each other, and send files.
For professionals who require maximum speed and control, deploying an FTP server is recommended. On Windows, this can be done through IIS or third-party programs like FileZilla ServerProtocol FTP It's less chatty than SMB and handles broken connections better, allowing downloads to resume.
⚠️ Warning: When using third-party software from untrusted sources, ensure the connection is secure. Passwords and personal data transmitted over open protocols on public networks can be intercepted by attackers.
The choice of a specific tool depends on the frequency of your tasks. For the occasional transfer of a couple of documents, Snapdrop will suffice, but for daily work with gigabytes of video, it's better to set up SMB or FTP once.
Frequently Asked Questions (FAQ)
Why is the Wi-Fi copy speed very low (less than 1 MB/s)?
Low speed is most often caused by using the 2.4 GHz band, which is very noisy, or by one of the devices connecting via the 802.11g/n standard. Speeds also drop if the router is located far away or behind thick walls. Try moving closer to the access point or switching to the 5 GHz band.
Is it possible to transfer files if one computer is Windows and the other is Linux?
Yes, this is possible. Linux supports the SMB/CIFS protocol well. In a file manager (such as Nautilus or Dolphin), select "Connect to server" and enter the Windows machine's address. You will need the Windows username and password.
Is it safe to share folders on a home network?
Within a trusted home network protected by a WPA2/WPA3 password, this is safe. However, if outsiders may connect to your Wi-Fi, it's recommended to set complex passwords for user accounts or disable public access when not in use.
How do I find out the IP address of a computer to connect to?
In Windows, open the command prompt (cmd) and type the command ipconfigYou're interested in the "IPv4 address" line. On macOS, open Terminal and enter ifconfig or look in the network settings.
