In the age of ubiquitous wireless connectivity, the need to lug around flash drives or find an Ethernet cable to transfer data between computers is becoming less important. Modern technologies allow for high-speed data exchange using only the capacity of your local network. Transferring files via Wi-Fi has become the de facto standard for home users and small offices where mobility and the absence of unnecessary physical infrastructure are important.
There are many scenarios where you need to urgently transfer gigabytes of photos, video archives, or heavy projects from one computer to another. This could be for backup purposes, document collaboration, or simply watching a movie from a media server on another device. The main advantage of this method is that it doesn't require a specific port or cable length, allowing complete freedom of movement within the router's coverage area.
However, despite the apparent simplicity, users often encounter problems with device visibility on the network or slow copy speeds. In this article, we'll explore the most effective methods, from built-in operating system tools to specialized software. You'll learn how to set up shared folder, use the function Nearby Sharing and even deploy your own FTP server for maximum control over the process.
⚠️ Attention: Data transfer speed directly depends on the Wi-Fi router standard. If your router only supports 2.4 GHz, speeds are unlikely to exceed 3-4 MB/s, while in the 5 GHz band, you can reach 20-40 MB/s and higher.
Using a shared network folder in Windows
The most classic and reliable method, which doesn't require installing additional software, is creating a shared network folder. This method is ideal for regularly exchanging large amounts of data between desktop computers. First, you need to ensure both computers are connected to the same Wi-Fi network and set the current connection to "Private" to prevent the system from blocking detection.
You should start the setup from the receiving or sending computer. You need to select the directory you plan to share. Right-click the folder, select "Properties," and go to the "Sharing" tab. Here, click "Advanced Setup" and check the box next to "Share this folder." In the section Permissions Make sure the Everyone group is checked for Full Control or Read/Write, depending on your needs.
After setting up access rights, it's important to check your network settings. Open Control Panel, go to Network and Sharing Center, and select Change advanced sharing settings. In the Private profile, both Turn on network discovery and Turn on file and printer sharing should be enabled. It's also recommended to disable password protection if you're on a trusted home network to avoid being constantly prompted for credentials when logging in.

- 🚀 To speed up work, you can map a network folder to a drive letter using the "Map network drive" context menu.
Nearby Sharing feature in Windows 10 and 11
Microsoft has implemented a convenient AirDrop alternative called "Nearby Sharing" into its operating systems. This tool uses a combination of Bluetooth for device discovery and Wi-Fi Direct for high-speed file transfers. This method is ideal for quickly sharing individual documents, photos, or links without the need to configure complex network permissions.
To activate the function, go to the system Settings (keys Win + I), then go to the "System" section and find "Nearby Sharing." Make sure the switch is set to "On." You can also adjust the visibility here: select "Everyone" if you want to share files with any device within range, or "My devices" to limit the sharing to only your PCs signed in with the same Microsoft account.
The transfer process is as simple as possible. Simply open the file you want to send, select the standard "Share" button in the app menu or File Explorer context menu, and select the target computer from the list of available devices. A pop-up notification will appear on the receiving end, asking if you want to save the file. Once confirmed, the direct transfer will begin over Wi-Fi.
☑️ Checking readiness for exchange
It's worth noting that this method has its limitations. It's not designed for transferring thousands of small files simultaneously—in that case, a network share is better. Furthermore, the distance between the devices should not exceed the standard Bluetooth range (approximately 10 meters without obstacles), otherwise the discovery process may not begin.
FTP Transfer for Advanced Users
For those who prefer complete control over the process and maximum speed, setting up an FTP server on one of the computers is an excellent solution. This method allows the use of specialized clients that support resuming interrupted downloads, batch transfers, and queue management. Unlike the standard Windows SMB protocol, FTP is less demanding on system resources when working with large numbers of files.
To implement this method, you don't need to install heavy server software. A lightweight FTP server, such as FileZilla Server, or even the built-in capabilities of some file managers, will suffice. After installing the server, you need to specify the root directory that clients will see and configure user accounts with access rights. It's important to remember the port; by default, it's 21, although it can be changed to any free one, for example, 2121.
ftp://192.168.1.55:2121On the client computer (the second PC), you'll need an FTP client, such as FileZilla Client or WinSCP. In the "Host" field, enter the server computer's IP address, along with the username and password you specified during setup. Once connected, you'll see the remote PC's file system displayed in two panes, allowing you to conveniently drag and drop files.
⚠️ Attention: When setting up an FTP server, Windows Firewall may block the incoming connection. You need to create an inbound connection rule for the selected port in the firewall settings.
Why is FTP faster than SMB in some cases?
The FTP protocol has lower overhead for service data and access rights checking for each individual file during batch transfers. While SMB (network folders) constantly communicates with the server to verify metadata, FTP simply transfers a stream of bytes, resulting in speed advantages when working with thousands of small files.
Using cloud storage as an intermediate buffer
While the question is about transferring files over Wi-Fi, we can't ignore the hybrid method, which is often the easiest for users with fast internet. Using cloud services like Yandex.Disk, Google Drive, or OneDrive allows you to sync files between computers without directly setting up a local network. The file is uploaded to the provider's server via Wi-Fi and then immediately downloaded to the second computer.
This method has its pros and cons. On the one hand, it doesn't require both computers to be on at the same time. You can download a file from your work PC and then download it to your home laptop later that evening. On the other hand, the speed is limited by your internet service provider, not your router. If you have gigabit Wi-Fi but slow internet, local methods will be much faster.
To optimize the process, many cloud clients feature a "LAN sync" feature. If this option is enabled and both computers are on the same network, the cloud storage client will detect the neighbor on the local network and transfer the file directly, bypassing the internet connection. This combines the convenience of the cloud with the speed of local Wi-Fi.

Specialized software for file transfer
The software market offers a variety of utilities designed specifically to solve file transfer problems. Programs like Send Anywhere, Feem or Resilio Sync They create their own secure network on top of your Wi-Fi infrastructure. They often bypass Windows restrictions and work on any operating system, including Linux, macOS, Android, and iOS.
The operating principle of such programs is usually simple: you install the client on both devices, launch it, and see a list of available devices. Transfer is initiated by selecting a file and entering a six-digit code or simply clicking the "Send" button. The software automatically finds the optimal route: if the devices are on the same network, the data will go via the local IP; if not, it will go through the developer's secure server (P2P tunneling).
The P2P (Peer-to-Peer) technology used in such apps deserves special attention. It allows data to be transferred directly between devices, bypassing central servers, ensuring high privacy and speed. Some apps can even work offline, creating their own Wi-Fi Direct access point if a router is unavailable.
Comparison of methods and characteristics table
The optimal method depends on your specific needs, technical literacy, and frequency of operations. For a one-time photo transfer from a phone or laptop, it's easiest to use Nearby Share or instant messaging apps. For ongoing work on large projects between a desktop PC and laptop, it's best to set up a network folder or FTP once.
Security is also important to consider. Open network folders on public Wi-Fi networks (such as cafes and airports) pose a risk of data leakage. In such cases, it's best to use specialized encryption software or transfer files over secure channels. Always check the network type in Windows: a "Public" network blocks most local transfer methods by default.
Below is a comparison table to help you quickly navigate the selection of a tool for your situation.
| Method | Speed | Difficulty of setup | Do you need internet? |
|---|---|---|---|
| Network folder (SMB) | High (depending on the router) | Average | No (local network only) |
| Nearby Exchange | Medium/High | Low | No |
| FTP server | Very high | High | No |
| Cloud services | Depends on the provider's tariff | Low | Yes (required) |
| Special software (P2P) | High | Low | No (for local transfer) |
⚠️ Attention: Operating system interfaces and router settings are subject to update. The location of menu items may vary slightly between different versions of Windows (10, 11) or router firmware. Always consult the manufacturer's latest documentation if the default path doesn't work.
Frequently Asked Questions (FAQ)
Why can't computers see each other on the network even though Wi-Fi is connected?
Most often, the problem lies with the network profile. If Windows considers your network "Public," it hides your computer from other devices for security reasons. Go to network settings and change the profile to "Private." Also, check that "Network discovery" is enabled in the advanced sharing settings.
What is the maximum transfer speed possible over Wi-Fi?
Actual speed depends on the router standard and adapters. At 2.4 GHz, speeds rarely exceed 3-4 MB/s. In the 5 GHz band, with AC (Wi-Fi 5) support, speeds of 20-40 MB/s can be achieved, and with AX (Wi-Fi 6), speeds of up to 80-100 MB/s and higher are comparable to a wired Fast Ethernet connection.
Is it safe to transfer files through a shared folder?
On a home network with a strong Wi-Fi password, yes, it's safe. However, if you're in a public place, it's best to avoid using public network folders. In such cases, it's preferable to use encrypted traffic programs or transfer files via secure protocols.
Is it possible to transfer files between Windows and macOS over Wi-Fi?
Yes, this is possible. macOS supports the SMB protocol used by Windows. You can connect to a Windows shared folder through Finder (Command + K -> smb://IP address). Conversely, Windows can see Mac shared folders if file sharing is enabled in macOS preferences.
