The modern pace of work and play requires constant information exchange between devices. Often, situations arise when you need to transfer gigabytes of photos, video archives, or heavy projects from one computer to another, but you don't have an external hard drive or flash drive of sufficient capacity at hand. It's in these situations that a wireless network becomes a real lifesaver, allowing you to set up a fast and convenient communication channel.
Transferring data from PC to PC via Wi-Fi It's not only convenient but also cost-effective, as it eliminates the need for additional equipment like network cables. A local network created by a router allows you to connect all devices in your home into a single ecosystem. You can access files on your desktop computer directly from your laptop while lying on the couch, or copy a work project in minutes.
In this article, we'll look at several proven methods for organizing file sharing. We'll examine standard operating system tools. Windows 10 And Windows 11We'll cover several options that don't require third-party software, as well as more advanced methods for experienced users. Whether you need to transfer a single document or create a full-fledged storage solution, you'll find a solution.
Preparing equipment and checking the network
Before setting up complex software, you need to ensure that the physical data transfer network is working properly. Both computers must be connected to the same wireless network. If one laptop is on the guest network and the other on the main network, or if one is using mobile data, a direct connection will not be established.
The most important parameter is network profile typeBy default, Windows may treat new networks as public, hiding your computer from detection by other devices for security reasons. To share files, you need to change this status to "Private Network." This will allow the system to open ports for local traffic.
⚠️ Important: Changing the network profile to "Private" is only allowed on trusted home or office networks. In public places (cafes, airports), always leave the profile set to "Public" to prevent intruders from scanning your ports.
It's also worth checking that Wi-Fi is enabled on both devices and that they can see each other. A simple test is to try pinging one computer's address from the other. If the packets get through, the physical connection is established, and you can move on to software configuration.
Setting up a shared folder in Windows 10 and 11
The most native and stable method, requiring no additional software, is to use the "Sharing" feature. This method is ideal for regularly sharing documents within a family or small office. First, select the folder whose contents you want to see on the second computer.
Right-click the folder and select "Properties." Go to the "Sharing" tab and click "Advanced." Here, check "Share this folder" and click "Permissions." In the window that opens, you can fine-tune the permissions: allow only reading of files or grant full permission to modify and delete.
However, simply allowing access isn't enough. You need to make sure network discovery is enabled in the Network and Sharing Center. Go to Control Panel → Network and Internet → Network and Sharing Center → Change advanced sharing settingsIn the "Private" profile, enable the following options:
- 🔹 Enable network discovery
- 🔹 Enable file and printer sharing
- 🔹 Allow Windows to manage HomeGroup connections
After applying the settings, the folder will be visible in the "Network" section on the second computer. If the system prompts for a username and password, enter the credentials of the user on the computer where the folder is located. This is a standard procedure for protecting data from unauthorized access.
☑️ Sharing setup checklist
Using Nearby Sharing
For one-time transfer of small files or photos, Windows 10 and 11 have a convenient built-in function Nearby Sharing (Around Us). It works similarly to AirDrop in the Apple ecosystem, using a combination of Bluetooth for discovery and Wi-Fi Direct for fast data transfer. This eliminates the need to configure complex network permissions.
To activate the function, open the Settings (keys Win + I), go to the "System" section and find "Shared Folders" or "Nearby." Turn on the toggle and select the visibility: "Everyone" or "Only my devices." Make sure Bluetooth and Wi-Fi are enabled on both computers.
The transfer process is extremely simple: simply open the file, click the "Share" button in the context menu or within the app, and select the desired PC from the list of available devices. The receiving end will receive a notification about the transfer request. Once confirmed, the file will be copied to the "Downloads" folder.
Why might the Close feature not work?
This feature requires Bluetooth Low Energy support and certain Wi-Fi drivers. If the devices are too far apart (more than 10 meters) or one of the computers is in sleep mode, detection may not work. This feature is also often blocked by third-party antivirus software.
The main advantage of this method is that it eliminates the need to know users' IP addresses or passwords. However, transfer speeds may be slower than using an SMB share, due to the additional overhead of discovery protocols. For files up to 500 MB in size, this is an excellent choice.
Setting up an FTP server for advanced users
If you require more flexible control over data transfer, create FTP servers (File Transfer Protocol) is the optimal solution. This method allows you to transfer files between different operating systems, such as from Windows to Linux or macOS, and provides a user-friendly management interface.
You don't need to buy expensive server hardware to implement this. You can use the built-in IIS (Internet Information Services) component in Windows or lightweight third-party utilities like FileZilla ServerAfter installing the server, you create a user, set a password, and specify the root folder to which access will be granted.
Connecting to such a server is done through any browser or file manager. Enter the address in the address bar in the format ftp://192.168.1.XX, where XX is the IP address of the server computer. The system will prompt you for the login and password you specified during setup.
| Parameter | Shared folder (SMB) | FTP server | Cloud services |
|---|---|---|---|
| Speed | High (depending on Wi-Fi) | Very high | Limited by provider tariff |
| Security | Medium (local area network) | High (with encryption) | Depends on the provider |
| Difficulty of setup | Low | Medium/High | Very low |
| Access from outside | Locally only | Possible (static IP required) | From anywhere in the world |
Using FTP is especially useful when automating backup processes or configuring access to media files on a Smart TV. The protocol supports resuming interrupted downloads, which is critical when transferring large amounts of data over an unstable connection.
Third-party programs for fast transfer
When built-in Windows tools seem too cumbersome or unstable, specialized utilities come to the rescue. Programs like Resilio Sync, Send Anywhere or Feem create their own secure network on top of your Wi-Fi infrastructure, minimizing the impact of system settings.
The principle behind their operation is usually simple: you install the program on both PCs, and they find each other using a unique code or QR code. Data is transferred directly (P2P) over the local network, without loading the internet or passing through the developers' servers, guaranteeing privacy.
- 🚀 Resilio Sync: Ideal for constantly synchronizing folders in the background.
- 📤 Send Anywhere: The best choice for one-time file transfer using a 6-digit code.
- 🔒 LocalSend: An open, encrypted solution that works offline.
A unique feature of such programs is that they often bypass Windows Firewall restrictions automatically by requesting permission to create a rule upon first launch. This eliminates the need for the user to manually delve into network settings.
However, it's important to remember that installing additional software increases the attack surface. Download programs only from the developers' official websites. On corporate networks, the use of such utilities may be prohibited by information security policies.
Troubleshooting and connection diagnostics
Even with proper configuration, errors can still occur. One of the most common issues is computers not seeing each other on the network. In this case, the first thing to check is Windows services. Click Win + R, enter services.msc and find services related to SMB And Network DiscoveryThey must be running and have the startup type set to Automatic.
Another common blocker is antivirus software. Third-party security suites can block incoming connections, deeming them suspicious. Try temporarily disabling your firewall or adding your home network to the list of trusted zones in your antivirus settings.
⚠️ Important: If you're using a dual-band router (2.4 GHz and 5 GHz), make sure both devices are connected to the same frequency. Some older routers may not be able to correctly forward discovery packets between different frequency bands.
It's also worth checking if your network adapter has a background work restriction. Find your Wi-Fi adapter in Device Manager, open its properties, and under the Power Management tab, uncheck "Allow the computer to turn off this device to save power." This will prevent the connection from dropping when the computer is idle.
Comparison of methods and selection of the optimal one
The choice of transfer method depends on your specific needs. For daily document management in the office or at home, setting up a shared folder is best. This requires a one-time setup, but then works seamlessly without the need for additional programs.
If you need to quickly transfer a couple of photos from your laptop to a friend's PC or to your own second computer, the "Nearby" feature or utilities like Send Anywhere are quicker to implement. They don't require IP addresses or access rights, and work on a click-and-send basis.
For professionals working with large amounts of data (video editors, designers), creating a dedicated FTP server or using a NAS (network-attached storage) system is the most productive solution. This ensures the maximum speed available to your Wi-Fi equipment.
Why is the speed of file transfer via Wi-Fi lower than via cable?
The wireless interface operates in half-duplex mode (reception and transmission are not simultaneous) and is susceptible to interference from other networks and household appliances. Furthermore, some bandwidth is consumed by overhead and error correction, reducing the actual file transfer speed by 30-50% compared to a gigabit cable.
Is it possible to transfer files if the router is not at hand?
Yes, modern versions of Windows allow you to create a direct Wi-Fi connection (Ad-Hoc) or use the Mobile Hotspot feature. One computer broadcasts the Wi-Fi, the other connects to it, and you set up a shared folder just as if both were connected to a home router.
Is it safe to share passwords and documents through a shared folder?
Data transmission is relatively secure within a home network protected by a WPA2/WPA3 password. However, if unauthorized access is available to your Wi-Fi network, your data may be intercepted. For critical files, use password-protected archives or specialized traffic encryption software.
