Modern users often need to quickly transfer photos, documents, or videos between devices. In the age of gigabit speeds, using flash drives or external hard drives seems archaic, especially when both devices are in the same room. Wireless technology Allows you to instantly establish data exchange without having to look for extra cables at hand.
Transferring files over a local network via a Wi-Fi router is not only convenient but also secure, as the data never leaves your home. Unlike cloud storage, there's no waiting for files to be uploaded to the server and then downloaded. Copy speed It directly depends on the capabilities of your router and network adapters, but even at standard frequencies, this method outperforms Bluetooth in all respects.
There are many methods for accomplishing this, from built-in Windows features to third-party utilities. Some methods require minimal configuration, while others provide full control over folder access rights. It's important to choose the option that best suits your operating system and data security requirements.
⚠️ Attention: Make sure both computers are connected to the same Wi-Fi network. If one device is using guest access or is connected to the 2.4 GHz band and the other to the 5 GHz band on different subnets, direct discovery may not work without additional router configuration.
Using the Folder Sharing feature in Windows
The most classic and reliable method, built into the Microsoft operating system, is to use the protocol SMBIt allows you to share any folder on one computer and make it accessible from any other device on the network. To get started, make sure the "Private" profile, not "Public," is selected in the network settings on both computers.
To activate this feature, go to the Control Panel and find the Sharing settings. Here, you'll need to enable network discovery and file sharing. After doing so, the system will allow other computers to see your device in the list of available resources. Without enabling these settings, your computer will be hidden from the outside world, even if the Wi-Fi connection is active.
Next, select the folder you plan to share. Right-click it, select Properties, and go to the "Access" tab. Click "Advanced Settings" and check the "Share" box. You can also configure permissions here: allow read-only access or grant full control, allowing you to delete and modify files.
☑️ Setting up sharing
To connect to the shared folder on the second computer, open File Explorer and enter the IP address of the first computer in the address bar. You can find it by opening the command prompt and entering the command ipconfigIf everything is done correctly, the system will ask for the login and password for the first computer account.
Transfer via Nearby Sharing
More recent versions of Windows 10 and 11 feature a feature similar to AirDrop in the Apple ecosystem. Called Nearby Share, it allows you to transfer files and links between nearby computers. The technology uses a combination of Bluetooth for discovery and Wi-Fi Direct for fast data transfer.
To enable this feature, open "Settings" from the Start menu. Go to "System" and find "Nearby Sharing." Make sure the toggle is turned on. You can also configure the visibility here: "Only my devices" (requires signing in to a single Microsoft account) or "Everyone around me" (available to all devices within range).
The transfer process is as simple as possible for the user. Simply right-click the desired file and select "Share" from the context menu. The system will automatically search for available devices. When the name of the target computer appears on the screen, click it.
⚠️ Attention: Nearby Sharing requires Bluetooth and Wi-Fi to be enabled on both devices. If the receiver is turned off or asleep, sharing will not begin. Also, make sure your firewall isn't blocking incoming connections for this service.
A pop-up notification will appear on the receiving end, asking if they want to save the file. Once confirmed, the transfer will begin over Wi-Fi. This method is typically faster than Bluetooth, but may be slower than directly configuring SMB folders when transferring large amounts of data (tens of gigabytes).
Why might Nearby Sharing not work?
The feature may not activate if Bluetooth or Wi-Fi services are disabled in Device Manager. Drivers are also often the issue: make sure you have the latest drivers for your wireless adapter installed from the manufacturer's official website. Older versions may not support the required discovery protocols.
Using cloud storage as an intermediate link
While this method technically uses the internet rather than a local network, it is often the easiest solution for transferring files between computers that may be in different physical locations but have access to Wi-Fi. Services like Google Drive, Yandex Disk or Dropbox create a virtual space accessible from any device.
Install a cloud storage client on both computers. Files placed in a synced folder on the first computer are automatically uploaded to the cloud and instantly appear on the second computer. This eliminates the need to configure complex network settings or search for IP addresses.
The main advantage of this method is automatic synchronization and the ability to access files from a phone or tablet. However, speed is limited by your internet service provider, especially the uploads channel. With no data limits, this is a convenient way to work with documents and photos.
Comparison of data transfer methods:
| Method | Speed | Difficulty of setup | Internet addiction |
|---|---|---|---|
| Shared Access (SMB) | High (up to 50-100 MB/s) | Average | No (local network only) |
| Nearby Sharing | Medium/High | Low | No (uses Wi-Fi Direct) |
| Cloud services | Depends on the tariff | Very low | Yes (required) |
| FTP server | High | High | No (local network) |
Specialized programs for transmission (TeamViewer, AnyDesk)
Remote control programs such as TeamViewer, AnyDesk or RustDesk, have built-in file transfer modules. Although their primary purpose is remote assistance, the "File Transfer" feature also works perfectly within a local network. This is a great option if standard Windows tools fail.
Install the program on both computers. Enter the remote device's ID and password in the appropriate fields. Once the connection is established, find the "File Manager" or "File Transfer" button in the program interface. A two-pane interface will open, displaying your PC's file system on the left and the remote computer's file system on the right.
Simply drag and drop the desired objects from one panel to another. The programs automatically compress data during transfer, which can speed up the process if there's network interference. They also bypass most firewall configuration issues by using their own secure communication channels.
⚠️ Attention: Remote access program interfaces are frequently updated. Button locations and tab names may differ from those described. If you can't find the transfer function, look for the folder icon or use the action menu at the top of the program window.
The unique feature of such utilities is that they can even work over the internet if the computers are located in different cities. However, for purely local transmissions (within a single apartment), they can create an unnecessary load on the processor due to traffic encryption, although modern processors handle this seamlessly.
Creating an FTP Server for Advanced Users
For those who prefer full control and don't want to depend on Windows settings, the ideal solution would be to deploy your own FTP serversThis is a classic file transfer protocol that works reliably on all operating systems, including Linux, macOS, and Windows.
There are many free server programs available, such as: FileZilla ServerAfter installation, you need to create a user, set a password, and specify the root folder to which access will be granted. In the server settings, specify the port (default 21) and ensure it is open in the firewall.
To connect on the client side, you can use any browser or file explorer. Enter the address in the address bar in the format ftp://192.168.1.XXThe system will prompt you for your previously entered login and password. After authorization, you will be able to access the files as you would any other network drive.
An example command to quickly check the availability of the FTP port:
telnet 192.168.1.105 21
The advantage of FTP is its versatility and the ability to fine-tune access rights for different users. You can create a guest account with write-only access (so they can share files with you) and a separate administrator account with full rights.
Is it possible to transfer files without a router?
Yes, you can create a direct Wi-Fi connection between laptops. To do this, launch "Mobile Hotspot" in Windows or use the command netsh wlan start hostednetwork. One laptop will become an access point, and the other will connect to it as a regular Wi-Fi router. Then, set up sharing in the same way as a regular network.
Troubleshooting and Questions (FAQ)
Despite the simplicity of the technology, users often encounter difficulties during initial setup. Below are answers to the most frequently asked questions to help you troubleshoot without calling a specialist.
Why can't computers see each other on the network?
Most often, the problem lies with the network profile. If Windows considers your network "Public," it hides your computer from detection for security reasons. Go to "Settings" → "Network & Internet" → "Wi-Fi" and switch the profile to "Private." Also, check that "Function Discovery Resource Publishing" is enabled in the "Services" menu.
What is the maximum transfer speed for Wi-Fi?
Speed depends on the Wi-Fi standard. At 2.4 GHz (N standard), actual speeds rarely exceed 3-4 MB/s. At 5 GHz (AC and AX standards), speeds can reach 40-80 MB/s and higher, comparable to fast flash drives. For large files, be sure to use the 5 GHz band.
Is it safe to transfer files through a shared folder?
Yes, if you're on a trusted home network. However, always set a password on the user account being granted access. Never share with "Full Control" permissions for all users without a password if others may be connecting to your Wi-Fi.
Is it possible to transfer a file from Windows to Mac or Linux?
Absolutely. The SMB protocol used by Windows is supported by macOS (via Finder → Go → Connect to Server) and Linux (via Nautilus or Dolphin). FTP or cross-platform programs like Resilio Sync are also universal options.
