In the age of ubiquitous digital interaction, the question of how to quickly transfer a large photo archive or work project from a desktop computer to a portable laptop remains extremely pressing. The use of USB drives is becoming a thing of the past, giving way to more elegant and technologically advanced solutions that don't require physical contact between devices. A local area network built on a wireless connection Wi-Fi, provides exactly this opportunity, allowing you to organize data exchange at high speeds comparable to a wired connection.
There are many scenarios where a user needs to synchronize the contents of two machines located in the same room. This could be backing up important documents, transferring a media library for viewing on a larger screen, or simply continuing work on another device. A key advantage of this method is its independence from internet bandwidth, as all traffic circulates exclusively within your home network between the router and clients.
Before proceeding to practical implementation, it is worth noting that modern operating systems such as Windows 10 And Windows 11, have built-in tools for this task. You don't need to install third-party software, although it may be more convenient in some specific cases. Below, we'll detail the main methods, their pros and cons, and provide step-by-step setup instructions.
Preparing equipment and checking the network
The foundation of successful data transfer is a stable connection. To ensure file copy speeds are reliable, both devices—the PC and the laptop—should be connected to the same access point. Ideally, it should be a Wi-Fi network. 802.11ac (Wi-Fi 5) or newer, operating in the 5 GHz range, since the 2.4 GHz frequency is often overloaded by neighboring routers and household appliances.
Make sure your operating system settings set your current network profile to "Private" or "Home," not "Public." In public mode, the system blocks other network members from discovering your device for security reasons, preventing direct file sharing. You can check this through the Network and Sharing Center, where the connection status is displayed.
⚠️ Attention: If you're using a corporate network with client isolation, devices won't be able to see each other even with the correct password. In this case, you'll need to consult with your system administrator or use alternative methods that don't rely on local discovery.
It's also worth checking that the discovery service is enabled on both computers. Without this step, the machines will act as if they were "deaf and dumb," ignoring connection requests. In Windows, this can be configured through the Network Control Panel, where you need to enable network discovery and file sharing.
Method 1: Shared folder (SMB) on the local network
The most classic and reliable method, working at the protocol level SMB (Server Message Block) involves creating a shared folder on one of the computers. This method is ideal for regular work, where you need to frequently access a specific set of files from different devices. Setting it up requires careful consideration, but the results are worth it.
To begin, select the folder on your PC whose files you want to see on your laptop. Right-click it and select "Properties." In the window that opens, go to the "Sharing" tab and click "Advanced." Here, check the "Share this folder" box and click "Permissions." Set "Read" or "Full Control" permissions for the "Everyone" group (or a specific user).
- 📁 Open the Control Panel and go to the Network and Internet section.
- 🔗 Select "Network and Sharing Center".
- 🛠 Click "Change advanced sharing settings."
- ✅ Enable the "Turn on network discovery" and "Turn on file and printer sharing" options.
After setting up access rights on the receiving device (laptop), open File Explorer and enter the source computer's IP address in the address bar. You can find it by running the command prompt (cmd) on the PC and entering the command ipconfigThe address will look like this 192.168.1.XEntering an address in the format \\192.168.1.X will open an authorization window where you need to enter the login and password of the main computer account.

Method 2: Nearby Share
In newer versions of the operating system Windows 10 And Windows 11 A feature similar to Apple AirDrop has been implemented. It allows you to instantly transfer files and links via Bluetooth and Wi-Fi Direct, without the need to create shared folders or know IP addresses. This is ideal for one-time transfers of several documents or photos.
To activate this feature, go to "Settings" (the gear icon in the Start menu), then "System," and find "Nearby Sharing." Turn on the toggle switch. You can also adjust the visibility here: select "Everyone" if you want to receive files from any device within range, or "My devices only" if they are signed in to the same Microsoft account.
The transfer process is extremely simple: simply right-click any file, select "Share" (the arrow icon) from the context menu, and select your laptop from the list of available devices. A notification will appear on the receiving end, which you must confirm to begin the download. Speed depends on the power of the Bluetooth modules and Wi-Fi Direct support.
⚠️ Attention: The Nearby Share feature may not work if Bluetooth is disabled on one of the devices or if the network card drivers don't support Wi-Fi Direct. Antivirus software may also block incoming transfer requests.
Why is my laptop not visible in the list of devices?
If you don't see the target device in the list of available devices for sharing, check that Bluetooth is enabled on both computers. Also, make sure both devices are on the same Wi-Fi network. Restarting the discovery service can sometimes help: in the command prompt with administrator privileges, run netsh wlan set hostednetwork mode=allowIf the problem persists, try temporarily disabling your firewall to test.
Method 3: Create an FTP server on your computer
For advanced users who require maximum flexibility and cross-platform support, rolling out your own is a great solution. FTP serversThis method allows you to connect to files not only from another Windows laptop, but also from smartphones, tablets, and Linux systems using any FTP client.
In Windows 10 and 11, the FTP server component is built into the system but disabled by default. To enable it, open Control Panel, select Programs and Features, then Turn Windows features on or off. Find Internet Information Services (IIS) in the list, expand the branch, and check the box next to FTP Server. After applying the changes, the system will install the necessary files.
The server is configured through IIS Manager. You need to create a new site, specify the path to the folder containing the files, and configure access rights (anonymous or authorized). After the server is launched, the connection is established via the address ftp://computer-IP-addressTo easily manage files on your laptop, you can use a free client. FileZilla or the built-in Windows Explorer.
The advantage of FTP is the ability to interrupt a large file transfer and resume it later, as well as convenient file system navigation, similar to working with regular folders. However, it's important to keep security in mind: while this isn't a critical issue when transferring over a local network, using FTP over the internet without SSL encryption is extremely dangerous.
Comparison of data transfer methods
The optimal method depends on your specific needs, the volume of data transferred, and the frequency of use. Below is a comparison table to help you decide which method is right for you.
| Method | Speed | Difficulty of setup | Best use |
|---|---|---|---|
| Shared folder (SMB) | High (up to 50 MB/s) | Average | Constant work with files |
| Exchange with the environment | Average (5-10 MB/s) | Low | Fast transfer of photos/documents |
| FTP server | High (up to 50 MB/s) | High | Access from different OS and devices |
| Cloud storage | Depends on the tariff | Low | Synchronization via the Internet |
| Network cable (LAN) | Maximum (100+ MB/s) | Low | Transferring hundreds of GB of data |
As the table shows, for regular use between two Windows computers, creating a shared folder is the most efficient option. It provides better performance and transparency. If you just need to share a few pictures, the "Nearby Share" feature will save you time on setup.
Alternative solutions: Cloud and software
Hybrid methods that use Wi-Fi for internet access shouldn't be discounted either. Services like Google Drive, Dropbox or Yandex.Disk Allows you to download a file to your PC and instantly view it on your laptop. This is convenient if your devices are in different physical locations, but your speed is limited by your provider's plan.
There are also specialized programs for transferring files over a local network, such as Feem or Snapdrop (works through a browser). They create a temporary tunnel between devices, bypassing complex Windows settings. The main difference between these programs is that they often use WebRTC technology to directly connect browsers, allowing data to be transmitted even without installing additional software.
Using third-party software is advisable in heterogeneous networks where Windows, macOS, Android, and Linux are running simultaneously. In such environments, standard Windows tools may be unstable or require complex firewall configurations.
⚠️ Attention: Program interfaces and the location of settings in Windows may change with the release of new updates. If you can't find the menu item described, use the system settings search or refer to the help for your specific software version.
Frequently Asked Questions (FAQ)
Why does the speed drop to 1-2 MB/s when transferring files via Wi-Fi?
Slow speeds are most often caused by using the 2.4 GHz band, which is highly susceptible to interference. Speed may also be limited by the older Wi-Fi standard (802.11g/n) on one of your devices. Try switching to a 5 GHz network and ensure your router supports modern standards.
Is it possible to transfer files if the router is not at hand?
Yes, you can create a hotspot directly on one of the laptops (using the "Mobile Hotspot" feature in Windows 10/11). The second computer will connect to this virtual network, and you can use shared folder or FTP methods, as they will be on the same local network.
Is it safe to share folders?
If you're on a trusted home network with a strong Wi-Fi password, the risks are minimal. However, it's not recommended to enable sharing with "Everyone" (without a password) if guests are allowed to connect to your network. Always use password protection for your Windows account.
How do I find out the IP address of a computer to connect to?
Open command prompt (press Win+R, enter cmd and press Enter). In the black window, enter the command ipconfigFind the "IPv4 Address" line in the section for your wireless adapter—this is the address you need (e.g., 192.168.0.15).
