In today's digital world, the need to quickly exchange data between devices is a constant. Users often find themselves needing to transfer gigabytes of photos, videos, or work documents from a laptop to a desktop computer, but don't have a flash drive with the appropriate capacity. Cloud storage can be too slow, and finding a LAN cable can be a real hassle.
Luckily, the wireless network Wi-Fi Provides an excellent alternative to physical media. A local area network (LAN) allows for high-speed data transfer right within an apartment or office. This solution doesn't require the purchase of additional equipment if both devices are already connected to the same router.
There are several proven methods, each with its own unique features. You can set up a shared folder for permanent access, use the Nearby Share feature in Windows 10/11, or use third-party software. The choice of a specific method depends on the frequency of use and the volume of files being transferred.
Checking basic network parameters
Before tackling complex sharing settings, you need to ensure the connection foundation is in place. Both devices—the laptop and the desktop—must be on the same local network. This means they're connected to the same router, even if one uses a cable and the other Wi-Fi.
The network profile is critical. Windows may treat a new connection as a "Public Network" by default, which automatically blocks the device from being visible to others. You need to change this status to "Private Network."
⚠️ Attention: Changing your network profile to "Private" makes your computer visible to other devices in cafes or airports. Always check your network type when connecting to public Wi-Fi.
To check your settings, follow these steps:
- 🔍 Click
Win + R, entercontroland press Enter. - 📡 Go to the "Network and Sharing Center" section.
- ⚙️ Make sure that “Private Network” is written under the name of your connection.
It's also worth checking if network discovery is enabled. In the same "Network and Sharing Center" menu, select "Change advanced sharing settings." Here, you need to enable the "Turn on network discovery" and "Turn on file and printer sharing" options.
Setting up a shared folder via Explorer
The most classic and reliable way to share data is by creating a shared folder. This method is ideal for regular work, when you need to constantly transfer files between devices without any extra steps.
Create a new folder on your drive or select an existing one. Right-click it and select "Properties." Go to the "Access" tab. Click "Advanced Settings."
In the window that opens, check the box next to "Share this folder." Below, in the "Permissions" button, make sure the "Everyone" group or a specific user has "Full Control" permissions if you plan to not only read but also delete or modify files.
☑️ Access setup checklist
To access this folder from another device, you'll need the IP address of the computer on which it was created. You can find it using the command line. Click Win + R, enter cmd and in the black window enter the command:
ipconfigFind the line "IPv4 address". It usually looks like this: 192.168.1.XX or 192.168.0.XXRemember or write down these numbers.
Using Nearby Share
Windows 10 and Windows 11 introduce a modern feature reminiscent of Apple's AirDrop. It's called Nearby Sharing. This method is convenient for one-time file transfers without setting up complex network permissions.
For this technology to work, both computers must support Bluetooth and Wi-Fi and be close enough to each other. The feature uses Bluetooth for discovery and Wi-Fi Direct for fast data transfer.
You can activate this feature through the system settings. Go to Settings → System → Shared Files (or "Nearby Share"). Make sure the toggle is on and the display is set to "Everyone nearby."
The transfer process is simple: right-click the file, select the "Share" (or "Transfer") icon, and select the destination computer from the list. A notification will appear on the receiving device asking if you want to save the file.
Why doesn't sharing with others work?
This feature may not work if your Wi-Fi or Bluetooth drivers are out of date. It's also often blocked by antivirus software or firewall settings that consider the connection suspicious. Make sure both devices are using the same Microsoft account or are in the same Homegroup.
Remote Desktop Protocol (RDP)
Sometimes a user needs more than just transferring a file; they need to fully control one computer from another. The built-in Remote Desktop Protocol (RDP) tool allows you to view the PC screen on your laptop and control it with your mouse.
This feature is only available in Windows Pro and higher. On the Home edition, the computer can only act as a client, not a server. To enable the server, go to Settings → System → Remote Desktop and toggle the switch.
To connect from a laptop, enter the computer name or its IP address in the Remote Desktop Connection app. The system will prompt you for the username and password of the host PC's user account.
There's an important caveat: when connecting via RDP, the host computer's local screen is locked. You won't be able to work on the PC keyboard and see the image on the laptop at the same time unless you use special workarounds.
| Method | Speed | Complexity | Best use |
|---|---|---|---|
| Shared folder | High | Average | Constant work with documents |
| Exchange with the environment | Average | Low | Fast photo/file transfer |
| Remote Desk | Depends on the network | High | Administration and assistance |
| Third-party software | High | Low | Universal transmission |
Third-party synchronization programs
If built-in Windows tools seem too complex or unstable, specialized utilities can help. They often work faster and don't require in-depth knowledge of network protocols.
A popular solution is the program SyncTraySizer (interface for Syncthing) or Resilio SyncThese apps create a P2P connection between devices. All you need to do is install the program on both computers, add a folder to sync, and enter the connection key (a QR code or a set of characters).
Another option is to use FTP servers. You can run a simple server on your PC (for example, using Total Commander or FileZilla Server), and then connect to it as a network drive on your laptop. This gives you direct access to the entire file system.
For gaming streamers or those who need minimal latency, there are programs like ParsecThey allow the desktop image to be displayed with minimal latency, effectively turning the laptop into a thin client for a powerful PC.
⚠️ Attention: When using third-party software, always download it from the developers' official websites. File-sharing programs are often targeted for malicious code.
Visibility Problems and Their Solutions
Despite proper configuration, computers may not "see" each other. Most often, the problem lies in Windows services. The Function Discovery Resource Publication service must be running.
To check, click Win + R, enter services.mscFind the specified service in the list, double-click it, and select the startup type as "Automatic," then click "Start." Do the same for the "DNS Client" service.
Antivirus software can also block the connection. If you're using a third-party antivirus (Kaspersky, ESET, Avast), check its network settings. They often have a "Public Network" profile, which should be changed to "Trusted" or "Home."
In rare cases, resetting the TCP/IP stack can help. Open a command prompt as administrator and enter:
netsh int ip reset
netsh winsock reset
After executing the commands, a system reboot is required. This will reset the network settings to factory defaults, removing any potential conflicts.
Questions and Answers (FAQ)
Is it possible to connect a laptop and a PC directly without a router?
Yes, this is possible. You can create a virtual hotspot on one device (using the "Mobile Hotspot" feature in Windows) and connect the second device to this network. The speed will depend on the power of the Wi-Fi adapter creating the hotspot.
Why does the speed drop to 1-2 MB/s when transferring files?
Wi-Fi speeds vary greatly depending on the band. If you're using the 2.4 GHz band, actual speeds rarely exceed 3-4 MB/s due to interference. For faster file transfers, use the 5 GHz band, where speeds can reach 40-80 MB/s.
Do I need the same password to log in to both computers?
No, account passwords can be different. However, to simplify access to shared folders without constant authorization requests, it's sometimes easier to create the same user with the same password on both PCs or disable the password prompt in the advanced sharing settings (not recommended for office networks).
Does this method work between Windows and macOS?
Yes, but there are some caveats. macOS uses the SMB protocol to access Windows shared folders. In Finder, select Go → Connect to Server and enter the IP address of your Windows PC. Reverse access (from Windows to Mac) requires setting up sharing on the Mac and may require entering your Apple ID account credentials.
Is it safe to keep public access open all the time?
If you're on a home network behind a router with NAT, the risk is minimal. However, if you frequently connect to public Wi-Fi, be sure to switch your network profile to "Public" to hide your PC from prying eyes.
