Every user faces the need to urgently move a ton of photos, work documents, or media files from one device to another. Using USB drives, such as flash drives or external hard drives, is a classic solution, but it's not always convenient or readily available. Fortunately, modern technology makes it possible to organize wireless data transmission at high speed, using the capabilities of the local network.
Transferring information over the air eliminates the need to search for physical media and allows you to work with multiple devices simultaneously. However, many users are still wary of complex settings or don't know where to begin the synchronization process. In fact, operating systems of the Windows and other popular platforms provide built-in tools that make this process simple and accessible even for beginners.
In this article, we'll take a detailed look at the most effective methods for sharing files between laptops connected to the same Wi-Fi network. We'll cover both standard operating system tools and proven third-party utilities that will help you quickly establish communication between devices without losing data quality.
Before starting setup, ensure both laptops are connected to the same wireless network. This is a fundamental requirement for most local networking protocols to work. If one device is connected to the guest Wi-Fi and the other to the main Wi-Fi, or if one is using mobile data, a direct connection will not be established.
Preparing equipment and setting up the network
The first step to successful data transfer is a properly configured network connection. The operating system must see other devices on the network and allow the exchange of information. In modern versions of Windows, this is controlled by a network profile setting. You need to go to Settings β Network & Internet β Status and make sure that the network type selected for the current connection is "Private".
If the profile is set to "Public," the system blocks your computer from being discovered by other devices for security reasons. This is standard protection in cafes or airports, but at home it can be disruptive. Switch the profile to "Private Network" to allow discovery.
It's also worth checking if network discovery is enabled. To do this, open Control Panel β Network and Internet β Network and Sharing Center β Change advanced sharing settingsHere, in the "Private" profile, you need to enable the "Turn on network discovery" and "Turn on file and printer sharing" options.
Sometimes antivirus software or a built-in firewall can block connections. If, after all the settings have been configured, the devices still don't see each other, try temporarily disabling your third-party antivirus for diagnostic purposes.
β οΈ Attention: Enabling sharing in public places (cafes, hotels) can expose your files to unauthorized access. Always check your network profile type before activating these features outside your home.
After completing these steps, restart your network adapters or laptops. This will allow the new settings to apply and the devices to register correctly on the local network. Now you can proceed directly to selecting a file transfer method.
Using Shared Folders and HomeGroup
The most reliable and traditional way to share large amounts of data is to create a shared folder. This method doesn't require any additional software and works at the operating system level. You create a folder, grant access to it, and it appears on the second laptop in the network environment.
To implement this method, create a new folder or select an existing one. Right-click it, select "Properties," and then go to the "Sharing" tab. Click "Advanced" and check "Share this folder." In the "Everyone" group permissions, we recommend setting "Read" or "Read and Write" if you need to edit files in addition to copying them.
On the second laptop, open File Explorer and find the "Network" section in the left pane. The name of the first computer should be displayed there. When logging in, you may be asked to enter the username and password for the first laptop's user account. This ensures data security.
βοΈ Check access settings
There's also a simplified version of sharing known as HomeGroup (in older versions of Windows) or simply "Nearby Sharing." In Windows 10 and 11, Microsoft has simplified this process by integrating it into the standard SMB protocol. You can simply right-click a file, select "Share with," and specify a specific user on the network.
The transfer speed using this method directly depends on the power of your Wi-Fi router. If you use the standard 802.11n or 802.11acSpeeds can reach 20-50 Mbps, which is quite comfortable for working with documents and photos. For 4K video files, the speed may be insufficient, and the process will take time.
Transfer via built-in Windows tools (Close Interaction)
Windows 10 and 11 introduce Nearby Sharing, a feature similar to Apple's AirDrop. It lets you transfer files and links between laptops using a combination of Bluetooth for discovery and Wi-Fi Direct for fast data transfer. It's one of the most convenient methods for one-time transfers.
To activate the feature, go to Settings β System β Shared FilesMake sure the "Proximity" toggle is turned on on both devices. Also, choose who can see your computer: "Everyone around me" (for temporary sharing) or "My devices" (requires signing in to a single Microsoft account).
The transfer process is as follows: you select a file, click the "Share" button in the context menu or within the app, and the system begins searching for nearby devices. Once the receiving laptop is found, a notification will appear on its screen asking if it wants to accept the file.
Why isn't "Close Interaction" working?
This feature may not work if Bluetooth is disabled on one of the devices, network discovery is turned off, or the Wi-Fi/Bluetooth drivers are out of date. Transfer is also impossible if the devices are on different subnets or are using guest Wi-Fi mode.
The main advantage of this method is that there's no need to configure IP addresses or shared folders. However, for this feature to work, both devices must support Wi-Fi Direct. If one of the laptops is very old, this method may not be available.
It's worth noting that "Nearby Interaction" is ideal for transferring documents, photos, and small videos. For archives tens of gigabytes in size, it's better to use a wired connection or create a shared folder, as Wi-Fi Direct connection stability can vary.
Third-party programs for fast synchronization
If built-in Windows tools seem too complex or unstable, specialized utilities can help. They create their own secure environment for data transfer, often bypassing complex network profile settings. The most popular solution is Resilio Sync (formerly BitTorrent Sync) or SyncTrayzor (interface for Syncthing).
The principle is simple: you install the program on both laptops, specify the sync folder on the first device, and receive a unique key or QR code. Enter this key on the second device, and the folders begin syncing directly via Wi-Fi.
Another popular option is the utility Feem or Send AnywhereThey work like a messenger: you select a file, see the second device's name in the list, and send it. The recipient confirms receipt, and the download begins. These programs can often work even without an internet connection, creating a local hotspot.
| Program | Transmission type | Complexity | Peculiarities |
|---|---|---|---|
| Resilio Sync | P2P (P2P) | Average | Continuous synchronization of folders |
| Send Anywhere | File sharing | Low | Transfer by 6-digit code |
| Feem | Local area network | Low | Works without internet (Wi-Fi Direct) |
| Syncthing | P2P | High | Complete openness and security |
Using third-party software is especially important when transferring files between different operating systems, such as from Windows to macOS or Linux. Synchronization protocols are usually cross-platform and independent of OS version.
When choosing a program, pay attention to ads in the free versions and speed limits. For regular use, open-source solutions like Syncthing, which have no hidden limits, are better suited.
Cloud storage as an intermediate link
While the question is about direct Wi-Fi transmission, one cannot ignore cloud technologies that also use a wireless connection. Services like Google Drive, Yandex Disk, Dropbox or OneDrive can act as an excellent intermediary if the laptops are in different physical locations but have internet access.
The process is simple: you upload a file from one laptop to the cloud, and download it from the second. Modern cloud storage clients can work in the background. You simply copy the file to a special folder on your disk, and it automatically appears on the other device.
The downside of this method is that it relies on internet speed, not just local Wi-Fi. If you have a metered data plan or slow download speed, transferring large files (movies, backups) will take a long time. However, for documents, this method is the most versatile.
Many cloud services support a "smart upload" feature, where files are stored in the cloud but displayed in File Explorer. They only take up disk space when opened. This saves space on your laptop's SSD, but requires a constant network connection to access full versions of the files.
Organizing your home media library (DLNA and FTP)
If your goal isn't just to transfer files, but to access your laptop's movie or music collection from another device (such as a Smart TV or tablet), consider setting up a media server. DLNA technology allows you to stream content over the network without first copying it.
For this you can use the built-in Windows media server or install Plex, Jellyfin or KodiYou specify folders with media files, and they become available to all devices on the network. You simply open a video on one laptop, and it plays on another or on a TV.
A more advanced option for IT professionals is to create an FTP server. In Windows, this can be done through IIS (Internet Information Services) or third-party lightweight servers like FileZilla ServerThe FTP protocol provides more stable transfer of large files and allows downloads to resume if the connection is interrupted, which is critical for unstable Wi-Fi.
β οΈ Attention: An FTP server without properly configured passwords and encryption (FTPS/SFTP) transfers data in cleartext. Avoid using open FTP on public Wi-Fi networks; only use it in a trusted home environment.
Setting up FTP may seem complicated, but it gives you complete control over your file system. You can create accounts with different access rights, limit speed, and monitor connection history.
Troubleshooting and speed optimization
Even with proper configuration, Wi-Fi transfer speeds can be disappointing. Often, they're only a fraction of the router's advertised speed. This is due to interference, channel congestion from neighbors, and technical limitations of the wireless protocol. A utility can be used for diagnostics. iperf3, which will show the actual bandwidth of the channel between two laptops.
If your speed is critically low, try switching your router to the 5 GHz band. This band is less crowded and provides better throughput, although it has a shorter range. Make sure both laptops support the standard. 802.11ac or 802.11ax (Wi-Fi 6).
Antivirus software also impacts speed. When transferring thousands of small files (for example, a folder containing source code or a photo library), the antivirus scans each file in real time, which creates a significant load on the CPU and disk, dramatically reducing speed. For bulk transfers, you can add the destination folder to the scanner's exclusions.
In conclusion, the choice of method depends on your needs. For one-time documents, use Close Collaboration, for ongoing project work, use a shared folder or Syncthing, and for watching movies on a TV, use a DLNA server. By combining these tools, you can create an effective data sharing ecosystem.
Do I need internet access to transfer files via Wi-Fi?
No, internet access is not required for a local area network (LAN) to function. Both laptops need to be connected to the same router (even if it's not connected to a provider) or directly via Wi-Fi Direct. SMB and FTP protocols work within your local network.
Why can't my laptop see another laptop on the network?
The most common causes are: different network profiles (one "Public", the other "Private"), a disabled "Function Discovery Provider Host" service in Windows, blocking by an antivirus, or being on different subnets (for example, guest mode is enabled on the router).
Is it safe to share passwords and personal information through a shared folder?
Transfers within a home network are relatively secure, but data is not encrypted by default in the SMB v1 protocol. SMB v2/v3 do have encryption. However, if an attacker is connected to your Wi-Fi, they can intercept your traffic. For sensitive data, it's best to use password-protected archives or specialized encryption software.
Is it possible to transfer files if one laptop has Windows and the other has macOS?
Yes, it's possible. macOS supports the SMB protocol out of the box. In Finder, select "Go" β "Connect to Server" and enter the IP address of your Windows computer. You can also use cross-platform programs like Resilio Sync or cloud storage services.
