A modern user rarely makes do with just one device. He has it in his pocket Android or iPhone, and at the table there is a powerful PC Or a laptop. Situations often arise when you need to urgently transfer photos, play a video from your phone on a big screen, or simply reply to a message without interrupting your work on the computer. Cables are constantly getting lost, connectors wear out, and Bluetooth is too slow for large amounts of data.
Fortunately, technology has come a long way. Today, there's no need to search for adapters or cloud storage with limited traffic. Local area network Wi-Fi Allows you to create a direct connection between devices, ensuring high transfer speeds and stability. This turns your smartphone into a fully-functional remote control or external storage device.
In this article, we'll cover all proven synchronization methods: from built-in operating system features to specialized software. You'll learn how to create shared folders, control your screen, and even use your phone as a webcam. The key is to understand the basic principles of a local network to avoid connection issues in the future.
Equipment preparation and basic requirements
Before configuring complex protocols, you need to make sure your infrastructure is ready to go. The foundation of any wireless connection is the router. Both devices—the computer and the smartphone—must be on the same local network. This means they are connected to the same router.
It's important to consider the frequency range. Modern routers support two standards: 2.4 GHz and 5 GHz. For transferring large files, 4K video, or streaming games, it's better to use the 5 GHz band. 5 GHzIt provides higher throughput, although it has a shorter range compared to 2.4 GHz.
⚠️ Important: If your router is broadcasting two different networks with similar names (for example, HomeWiFi and HomeWiFi_5G), make sure both devices are connected to the same one. Being on different subnets can block device detection.
It's also worth checking your computer's firewall settings. Often, antivirus software or built-in protection Windows Defender may block incoming connections, considering them suspicious. For the methods described below to work correctly, network discovery must be enabled.
- 📶 Make sure both devices are connected to the same Wi-Fi network.
- 🔒 Make sure the network type in Windows is set to "Private" and not "Public."
- 🔄 Update your PC's wireless adapter drivers to the latest version.
- 📱 On your phone, turn off data saving mode for the app you're using.
Using Link to Windows
The most integrated way for users Windows 10 And Windows 11 in conjunction with Android — is a native "Link to Windows" app. Microsoft and Google are actively developing this protocol, allowing you to mirror your smartphone's screen directly to a PC monitor and control apps.
To get started, open the Link to Windows app (formerly known as Your Phone) on your computer. Download the app on your smartphone. Link to Windows from the store Google PlayThe pairing process usually occurs by scanning a QR code displayed on the monitor screen.
After successful pairing, you'll have access to your gallery, recent photos, SMS messages, and call history. You can drag and drop images directly from the app interface to your desktop. Screen sharing latency is minimal if your router supports the standard. Wi-Fi 5 or later.
It's worth noting that functionality may vary depending on the phone model. Devices Samsung, Honor And Surface Duo have the deepest integration, allowing you to run multiple mobile applications simultaneously in separate windows on your desktop.
Organizing shared access to folders via SMB
If your goal is to work with files without installing unnecessary software on your phone, the ideal option is the protocol SMB (Server Message Block). It's built into Windows by default and allows you to share a folder on your computer, making it visible to your smartphone's file manager.
First, select the folder on your PC you plan to use. Right-click it, select "Properties," and then go to the "Sharing" tab. Here, click "Advanced" and check "Share." Under Permissions, make sure your user has permission to Reading And Recording.
⚠️ Warning: When sharing, the system may warn you about security risks. Make sure you trust all devices connected to your Wi-Fi network. Do not share Windows system folders.
On your smartphone you will need a file manager with network support, for example, CX File Explorer, Solid Explorer Or the built-in Google Files app. In the menu, select "Network" → "New Connection" → "Remote Storage" (or SMB). The system will automatically find your computer in the list of available devices.
To log in, you'll need to enter your Windows account login and password. If you use a PIN to log in, it may not work—you'll need the password for your Microsoft account or local user account. Once mounted, the folder will be accessible as a regular disk partition.
| Parameter | Description | Recommendation |
|---|---|---|
| Protocol | SMB v2 / v3 | Use the latest version for security |
| Port | 445 | Standard port, do not change unless necessary |
| Encoding | UTF-8 | To correctly display Russian file names |
| Anonymous login | Disabled | Requires authorization to protect data |
Transfer files via FTP server on a smartphone
Sometimes it's more convenient to do it the other way around: turn your smartphone into a server and use your computer as a client. Protocol FTP (File Transfer Protocol) is ideal for quickly transferring files back and forth without installing drivers on your PC.
Most advanced file managers on Android (for example, MiXplorer, ES File Explorer or specialized WiFi FTP Server) have a built-in server launch function. You just need to press the "Start" button, and the application will display an address like ftp://192.168.1.5:2221.
Enter this address into the address bar of any Windows Explorer (This PC → address bar at the top). After pressing Enter, the contents of the phone's memory will open as a regular folder. You can copy, delete, and rename files directly.
Why is FTP better than Bluetooth?
FTP over Wi-Fi provides transfer speeds of up to 10-20 MB/s and higher, while Bluetooth is limited to 1-2 MB/s even in modern versions. Furthermore, FTP doesn't require re-pairing devices each time.
The advantage of this method is its versatility. You don't need any special programs on your computer; the built-in File Explorer is sufficient. However, it's important to remember that FTP doesn't encrypt traffic by default, so it should only be used on a secure home network.
Real-time synchronization with Syncthing
For those who need constant automatic synchronization of certain folders between devices, the best solution would be the program SyncthingThis is an open-source project that operates on a P2P (peer-to-peer) basis and does not use third-party servers to store your data.
Install the Syncthing client on your PC (via the official website or app store) and the app on your smartphone. Upon first launch, each device will receive a unique ID. You'll need to pair the devices by scanning a QR code or entering the ID manually.
Once paired, select the folder on your computer you want to sync and make it accessible to your phone. Your phone will prompt you to accept the folder and select a save location. From that point on, any changes you make (adding photos, editing documents) will instantly be reflected on both devices via Wi-Fi.
- 🔄 Works without the Internet, only through a local network.
- 🔐 Full end-to-end encryption of transmitted data.
- ⚡ Instant synchronization of changes in real time.
- 💾 Supports file versioning (you can restore deleted files).
This solution is especially valuable for photographers or video makers who need to have access to footage on a large screen immediately after shooting for editing or color correction, without wasting time on manual copying.
