In today's digital world, the need to quickly transfer large amounts of data between devices arises regularly. Every user is familiar with the situation of needing to transfer archives of photos, videos, or work projects from one laptop to another. Using USB drives or external hard drives often becomes inconvenient due to low write speeds and the constant need to physically move devices. This is why the question arises, How to transfer folders from one laptop to another via WiFi, remains one of the most relevant for equipment owners.
Wireless technology allows for data exchange without unnecessary wires, using your existing local network. Modern communication standards provide sufficient bandwidth for comfortable multimedia content management. Unlike cloud services, direct data transfer over a local network is not dependent on internet speed or provider tariffs. This is especially important when working with confidential information that you don't want to upload to third-party servers.
There are several proven methods for accomplishing this task, each with its own unique features. You can use built-in Windows operating system tools, set up an FTP server, or use specialized software. The choice of a specific method depends on the OS version, hardware specifications, and security requirements. In this article, we will examine the most effective algorithms in detail.
Preparing equipment and setting up the network
Before starting the procedure, you must ensure that both devices are in the same information space. Local area network — This is the foundation upon which the entire data exchange process is built. Both laptops must be connected to the same router, either via cable or wirelessly. If you're using a public network, such as in a cafe or office, ensure the security settings allow the devices to "see" each other.
An important step is checking the network profile type. By default, Windows may assign new connections the "Public Network" status, which prevents your device from being visible to others. You should change this setting to "Private Network" or "Home Network." This can be done through the Network and Sharing Center or through the pop-up notification when you first connect. Without this step, further actions may be unsuccessful.
⚠️ Note: When switching your network profile to "Private," the system may ask you to confirm your action. Make sure you are in a trusted location, as this makes your computer visible to other devices within range of the router.
It's also worth checking whether network discovery is enabled. This is a feature that allows a computer to announce its presence on the network and find other active nodes. It's usually activated automatically when you select a private profile, but in corporate environments, it may be disabled by the administrator. Checking these basic settings will save time on troubleshooting later.
☑️ Checking readiness for transfer
Creating a shared folder using standard Windows tools
The most common method, which doesn't require installing additional software, is using the sharing feature. It's ideal for regularly sharing files on a home network. To start, select the directory you want to share and open its properties from the context menu. The "Access" tab contains all the necessary tools for setting permissions.
Click the "Advanced Settings" button and check the "Share this folder" box. Here you can also configure permission levels for different users. You can allow others to only read files or also modify and delete them. For increased security, we recommend creating separate user accounts or using guest access with limited rights if the transfer occurs in a trusted environment.
After setting up the first device, move on to the second laptop. Open File Explorer and go to the "Network" section. If everything is set up correctly, you'll see the name of the first computer. Double-clicking it will grant access to the shared resources. When you first log in, the system may prompt you for the username and password for the user account on the remote computer. This is a standard Windows security procedure.
| Setting parameter | Recommended value | Impact on work |
|---|---|---|
| Network profile | Private network | Opens ports for local exchange |
| Network discovery | Included | The computer is visible in the list of devices |
| File sharing | Included | Allows data transfer |
| Password protection | Depends on trust | Requires authorization to access |
Using Nearby Sharing
Newer versions of the operating system, such as Windows 10 and 11, now feature a convenient Nearby Share feature. It works similarly to AirDrop in the Apple ecosystem and allows you to transfer files and links in just a few clicks. The technology uses a combination of Bluetooth for discovery and WiFi Direct for fast data transfer, ensuring high speeds without the need for complex setup.
To enable this feature, go to System Settings from the Start menu. Select "System," then find "Nearby Sharing." Make sure the toggle is set to "On." You can also configure visibility here: whether everyone in your neighborhood can send you files, or only your personal devices. Bluetooth must be enabled on both laptops for this feature to work.
The transfer process is extremely user-friendly. Simply right-click a file or folder, select "Share," and select the target laptop from the list of available devices. A notification will appear on the receiving end requesting permission to save. After confirmation, the download will begin. This method is ideal for one-time transfers of small to medium amounts of data.
⚠️ Note: The Nearby Share feature may not work correctly if one of your devices has outdated WiFi or Bluetooth drivers. In this case, update the software through the Device Manager.
The main advantage of this method is that there's no need to specify IP addresses or configure folder access rights. The system automatically finds the nearest device and establishes a secure connection. However, it's worth keeping in mind that when transferring very large files (tens of gigabytes), connection stability may be lower than when using a wired local network.
Why can't I see my device in the exchange list?
Make sure both computers are signed in to the same Microsoft account or have both devices added to your contacts. Also, check whether one of the laptops is in sleep mode.
Setting up an FTP server for advanced users
For those who prefer complete control over the process and maximum speed, deploying an FTP server is the optimal solution. This method allows you to work with the remote laptop's file system as if it were a local drive. There are many free programs for creating an FTP server, such as FileZilla Server or the built-in IIS component in Windows.
Let's look at setting it up through a popular FileZilla ServerAfter installation, launch the management interface and add a new user. In the user settings, specify the path to the directory to be shared and set access rights (read, write, delete, create lists). It's important to set a strong password, as the FTP protocol transfers data in cleartext without encryption.
On the client side (the second laptop), any FTP client or even the standard Windows Explorer will suffice. In the Explorer address bar, enter the address in the following format: ftp://server-ip-addressAfter entering your login and password, you'll be able to access your files. Transfer speeds in this mode are limited only by your WiFi router's capabilities and often reach 10-15 MB/s or higher.
The main advantage of FTP is the ability to interrupt a transfer and resume it later, as well as access files from any device, including smartphones and tablets. Furthermore, this method is less resource-intensive than forwarding SMB folders in Windows. However, initial setup requires care and an understanding of network addresses.
Specialized software for synchronization
If the built-in tools seem too complex or unstable, third-party programs can help. The leader in this niche is the utility SyncthingIt is a decentralized file synchronization system that works directly between devices (P2P), without using cloud servers for data storage.
Installing Syncthing on both laptops takes just a few minutes. Once launched, the program generates a unique device ID. You need to add a partner device by entering this ID. After mutual confirmation, the laptops will find each other on the network and begin syncing the specified folders. A key feature is continuous syncing: if a file is changed on one laptop, it will automatically update on the other.
Other popular alternatives include Resilio Sync (formerly BitTorrent Sync) and Send Anywhere. They offer similar functionality, but may have different interfaces and additional features, such as link sharing or temporary access keys. The choice of a specific app depends on personal preference and the need for cross-platform support.
Using such programs eliminates the headache of manually transferring files. You simply work in a specific folder, and the program automatically tracks changes. This is especially convenient for photographers, video editors, and programmers working with distributed file systems. At the same time, the data remains completely under your control.
Troubleshooting and speed optimization
Even with proper setup, users may experience slow speeds or dropped connections. This is often due to WiFi signal interference or an outdated connection standard. Make sure both laptops support the standard. 802.11ac (WiFi 5) or newer, and operate in the 5 GHz band. The 2.4 GHz frequency is highly susceptible to interference from household appliances and neighboring networks.
Another common problem is antivirus software. Third-party firewalls may block incoming connections, deeming them suspicious. If access errors occur, try temporarily disabling network protection or adding an exception rule for the local subnet (e.g., 192.168.1.0/24).
If the transfer speed is critically low, check your bandwidth usage. Using torrents or streaming on other devices on the network can choke local traffic. It's also a good idea to update your network adapter drivers from the manufacturer's official website, as standard Windows drivers don't always utilize the hardware's full potential.
⚠️ Note: Router and operating system settings interfaces may differ depending on the firmware version or Windows update. If you can't find the item described, use the settings search or refer to the manufacturer's documentation.
What should I do if it says "No network access"?
Check that the "Function Discovery Resource Publishing" service is enabled in services.msc on both computers. Without it, Windows will not be able to correctly display network resources.
Do you need internet access to transfer files via WiFi?
No, internet access is not required. To transfer data, both laptops need to be connected to the same router, even if the router itself is not connected to the global network. Data is transferred within the local network.
What is the maximum transfer speed for WiFi?
Speed depends on the WiFi standard and distance. Under ideal conditions, 40-80 MB/s of real-world traffic can be achieved on the 5 GHz frequency. On the 2.4 GHz frequency, speeds typically don't exceed 3-5 MB/s.
Is it safe to transfer files through a shared folder?
On a home network with trusted devices, yes. On public networks (cafes, hotels), using shared folders is dangerous. In such cases, it's better to use encrypted software like Syncthing or a VPN.
Why doesn't the second laptop see the first one on the network?
Most often, the problem lies in the network profile ("Public" instead of "Private") or a disabled discovery service. Also, check that the computer names are different and don't contain Cyrillic characters.
