Transferring information between computers without flash drives or external drives is a challenge faced by every modern user. The speed of modern routers allows for the transfer of gigabytes of photos, videos, and documents in minutes, eliminating the need to search for adapters.
There are several proven methods of organization local network There are various file sharing options, each with its own advantages depending on the data volume and device operating systems. We'll explore both built-in Windows tools and third-party utilities that ensure maximum speed.
The key to successful transfer is that both devices must be on the same wireless network. If the router is distributing internet and both laptops are connected, you're ready to go; all that's left is to configure the access settings correctly.
Using Nearby Share in Windows 10 and 11
Modern versions of Microsoft's operating system implement a native protocol that allows for instant file sharing between nearby devices. This technology, known as Nearby Sharing, uses a combination of Bluetooth for discovery and Wi-Fi Direct for fast data transfer, making the process seamless for the user.
To activate this feature, open the system settings and go to the "System" section, where you'll find the "Sharing" tab or the separate "Nearby Sharing" option. Here, turn on the activation toggle switch and select the device's visibility: "Only my devices" (requires signing in to a single Microsoft account) or "Everyone around me" (available to all devices within range).
The transfer process is extremely simple: just right-click the file, select "Share," and see the second laptop's name in the list of available devices. The recipient will see a pop-up notification asking if they want to save the file, which they must confirm.
⚠️ Attention: This feature may not work correctly if one of your laptops has the "Metered Connection" mode enabled in the Wi-Fi settings, as the system blocks background transfers of large amounts of data to save traffic.
It's important to note that the speed of this method directly depends on the power of the wireless module and the Wi-Fi standard (ac or ax). When transferring files larger than 10 GB, the process can take significant time, so it's best to consider other options for archives.
Setting up a shared folder on a local network
The classic method, which remains the most reliable for transmitting large amounts of information. Creation shared folder (Shared Folder) allows you to organize constant access to files from any device on the network without the need to re-confirm each operation.
To get started, make sure your current network profile is set to "Private" rather than "Public." In the Network and Network Control Panel, find "Change advanced sharing settings" and enable network discovery, as well as file and printer sharing.
Next, create a folder and add the "Everyone" user with read and write permissions to the "Access" tab in its properties. The system may prompt you to confirm the security changes, where you must also specify the appropriate permissions for the "Everyone" group.
☑️ Shared Folder Setup Checklist
On the second laptop, to access resources, simply open "This PC," select "Network" in the side menu, and find the name of the first device. If the computer isn't visible, you can directly enter its IP address in the File Explorer address bar, preceded by two backslashes, like this: \\192.168.1.5.
Troubleshooting password access issues
If the system constantly asks for a username and password and you don't want to enter them, you can enable password-less access in the "Everyone" group on the receiving computer. However, this reduces network security by making the folder accessible to all connected devices, including guest smartphones.
Copy speed on a local network is limited only by the bandwidth of your router. Using the Wi-Fi 5 (802.11ac) standard, actual speeds can reach 40-50 MB/s, which is comparable to the write speed of some USB flash drives.
Transfer data via built-in FTP server
For advanced users who require maximum flexibility and stability, deployment is a great solution. FTP servers on one of the laptops. This method allows you to use specialized clients that support file download resumption if the connection is lost, which is critical when transmitting over an unstable Wi-Fi signal.
In Windows, you can use the built-in IIS component or third-party lightweight servers, such as FileZilla Server. After installation, you need to create a new user, assign them a home directory, and set access rights (read, write, and delete).
The client-side connection is made through any browser or file manager that supports the FTP protocol. Enter the address in the address bar in the format ftp://192.168.1.X, after which you will need to log in with the created credentials.
| Parameter | Description | Recommended value |
|---|---|---|
| Port | Port number for connection | 21 (standard) |
| Protocol | Connection type | FTP or FTPS (secure) |
| Encoding | To support Russian file names | UTF-8 or Windows-1251 |
| Transmission mode | Passive or active | Passive |
Using the FTP protocol is especially important if you need to transfer thousands of small files, since the standard Windows Explorer often freezes when counting millions of objects, while FTP clients handle the task queue much more efficiently.
Third-party utilities for fast transfer
If you don't want to mess around with setting up access rights and IP addresses, specialized programs that work on the P2P (Peer-to-Peer) principle will come to the rescue. The leader in this niche is the utility Resilio Sync (formerly known as BitTorrent Sync) or cross-platform Syncthing.
They work by creating a unique link or QR code. You install the program on both laptops, scan the code with the camera or enter a key, and the devices will find each other even over the internet if they're not on the same Wi-Fi network, although speeds will be higher over a local network.
The advantage of these solutions is that there is no file size limit and the ability to synchronize folders in real time. A change to a document on one laptop will automatically update it on the other, making it convenient for collaboration.
Another popular option is to use web services like Sharedrop.io or Portal by PushbulletThey don't require software installation: simply open the website in the browser on both laptops, and drag and drop files directly through the web page interface.
⚠️ Attention: When using third-party P2P or cloud-based services, ensure that the transfer is not encrypted on the intermediary's servers if the data is sensitive. Local transfers via IP address are more secure in this regard.
Comparison of transmission methods and their effectiveness
The optimal method depends on your specific needs: a one-time photo transfer from your phone, daily document management, or system backup. Each method has its own strengths and weaknesses, which should be considered before you begin.
Built-in Windows tools are fine for occasional use, but can be finicky when configuring a firewall. Third-party software is more convenient, but requires installing additional components, which isn't always feasible on corporate devices.
Below is a comparison table to help you choose the right tool based on your priorities.
| Method | Speed | Difficulty of setup | Best suited for |
|---|---|---|---|
| Exchange with the environment | Average | Low | Photos, documents, fast transfer |
| Shared folder (SMB) | High | Average | Constant work, large archives |
| FTP server | Very high | High | Technical specialists, unstable network |
| Third-party software | High | Low | Users who value convenience |
Common problems and solutions
Even with proper configuration, users may experience access errors or slow speeds. Often, the problem lies with the wireless adapter's power-saving settings, which attempt to conserve power and reduce signal strength.
In the Device Manager, under the Wi-Fi adapter properties, on the "Power" tab, uncheck "Allow the computer to turn off this device to save power." This will ensure stable operation of the module at maximum frequencies.
Another common issue is different network security levels. If one laptop is connected to a private network while the other sees the network as public, Windows may block detection. Check the network type in the Network and Sharing Center and match them.
⚠️ Attention: Your antivirus software may be blocking incoming connections over your local network. If all else fails, temporarily disable your antivirus's firewall to test this hypothesis.
It's also worth checking that AP Isolation mode isn't enabled on your router. This feature, designed for hotels and cafes, prevents devices within the network from seeing each other, allowing only internet access.
What to do if the transfer speed drops to 1-2 MB/s?
Most likely, one of the laptops is connected to the 2.4 GHz band, which is very noisy. Try connecting both devices to the 5 GHz network if your router supports dual-band operation.
Questions and Answers (FAQ)
Is it possible to transfer files if laptops are connected to different Wi-Fi routers?
No, not using standard Windows tools (a shared folder); the devices must be on the same subnet. However, programs like Resilio Sync or TeamViewer can transfer data over the internet using external servers or forwarding, but the speed will depend on the ISP's upload speed.
What is the theoretical maximum transfer speed over Wi-Fi?
When using the Wi-Fi 5 (802.11ac) standard, the actual speed under ideal conditions is approximately 400-500 Mbps (50-60 MB/s). The Wi-Fi 6 (802.11ax) standard enables speeds of up to 800-900 Mbps, which is comparable to a 1 Gbps wired connection.
Is it safe to share passwords and personal information through a shared folder?
If you're on a home network, the risk is minimal. In public places (cafes, airports), using a shared folder is dangerous, as other network users may attempt to access it. In such cases, use encrypted archives or a VPN tunnel.
Why do I get the error "File name too long" when copying?
Windows has a file path length limit of 260 characters. When copying a deep folder structure over a network, the path may exceed this limit. Solution: Compress the folder into an archive (ZIP/RAR) before transferring, or use utilities like Robocopy with the following key: /longpaths.
