In the age of cloud storage and messaging, local data transfer may seem archaic, but it remains critical for working with large volumes of information. When transferring gigabytes of video archives, project source files, or database backups, local network speeds often exceed the capabilities of the internet. Local Area Network (LAN) Allows direct data exchange between devices without the use of external servers, guaranteeing privacy and high speed.
There are many ways to accomplish this, and the choice of a specific method depends on the operating system, Windows version, and your level of technical expertise. We'll cover both classic methods using built-in Windows tools, as well as alternatives that may be more convenient in certain situations. It's important to understand that connection stability directly depends on signal quality. router and the distance between devices.
Before you begin setup, make sure both devices—the desktop computer and the laptop—are connected to the same wireless network. If you're using a guest network or isolated VLANs, standard discovery methods may not work without adjusting your router's security settings.
Basic network setup and device discovery
The first step to successful data transfer is properly configuring your network profile. Windows may consider your home network "Public" by default, which automatically blocks your computer from being visible to other devices for security reasons. You need to change this status to "Private network" to allow discovery.
To do this, go to Settings → Network & Internet → StatusIn the connection properties section, change the profile to "Private." Then, open "Sharing options" in the "Network and Sharing Center." Here, you need to enable network discovery and file sharing. Network profile determines which firewall rules apply to your connection, so this step cannot be ignored.
⚠️ Warning: If you're in a public place (cafe, airport), enabling network discovery can make your personal files visible to attackers. Use this method only on trusted home or office networks.
After changing settings, the system may take a few seconds or even a restart of the discovery service for the changes to take effect. Check if your computer is visible in the "Network" section of Windows Explorer on the other device. If the devices can see each other but access is denied, the issue lies with the access rights to a specific folder.
It's also worth mentioning that in modern versions of Windows 10 and 11, Microsoft is phasing out older protocols like SMBv1 in favor of more secure versions. Make sure support is enabled on both devices. SMBv2/SMBv3, otherwise the connection may simply fail or be unstable.
This is especially true if you're trying to connect a new Windows 11 laptop to an older Windows 7 computer.
Creating a Shared Folder for Access
The most reliable and traditional way to share data is to create a shared folder. This method requires no additional software and operates on the NTFS file system. You simply select a directory, share it over the network, and it appears on the other device as a network drive.
To share a folder, right-click it, select "Properties," and go to the "Sharing" tab. Click "Advanced" and check "Share." It's best to specify a specific user or the "Everyone" group (with caution) in the permissions, granting them read and write permissions. SMB protocolThe method used for this ensures transparency of operation - the files will appear as part of the local file system.
An important detail is the user account. To access the shared folder from another computer, the system may request a login and password. Credentials The passwords must match those used on the computer where the folder is located, or identical accounts with identical passwords must be created on both computers. On a home network, a special "share" user with a simple password is often created to simplify access.
If you plan to transfer files regularly, it makes sense to map the network folder as a separate drive. In File Explorer, click "This PC" → "Map network drive," select the drive letter, and enter the path to the resource in the following format: \\ComputerName\Folder or \\IP address\FolderThis will eliminate the need to search for the device in the network environment each time.
It's worth noting that the copy speed in a shared folder is limited by the bandwidth of your Wi-Fi connection. When using the 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6) standard, speeds can reach 50-100 MB/s or higher, which is comparable to a wired Fast Ethernet connection, but still inferior to a gigabit cable.
Using Nearby Share in Windows 10/11
In newer versions of the operating system, Microsoft has implemented a feature reminiscent of Apple's AirDrop called "Nearby Sharing." This method is ideal for quickly transferring individual files, photos, or links without the need to set up complex network connections.
To activate the function, go to Settings → System → Shared Files (in Windows 11 the path may be slightly different: Settings → System → User Experience). Turn on the "Nearby Sharing" switch and choose who can see your computer: all nearby devices or only your personal devices linked to a single Microsoft account. Bluetooth Here it is used for the initial discovery and handshake, and the data transfer itself is done via Wi-Fi Direct, which ensures high speed.
☑️ Checking readiness for exchange
The transfer process is extremely user-friendly. Simply right-click the file, select "Share," and your laptop or PC will appear in the list of available devices. The receiving end will receive a notification asking if they want to save the file. This is a great option for irregular transmission small amounts of data.
⚠️ Note: The Nearby Sharing feature may not work correctly if one of the devices has outdated Wi-Fi or Bluetooth drivers installed, or if your antivirus software is blocking discovery packets.
The main advantage of this method is that there's no need to enter passwords or specify IP addresses. However, for large files (tens of gigabytes), this method may be less stable than creating a permanent shared folder, as the connection is established dynamically and can be lost if the signal is lost.
Setting up an FTP server for advanced users
For those who need full control over the transfer process, the best solution would be to deploy their own FTP servers (File Transfer Protocol). This method offers the most flexible access rights settings, action logging, and often faster transfer speeds for large files compared to standard SMB.
Windows has a built-in IIS (Internet Information Services) component that allows you to set up an FTP server, but setting it up can be cumbersome for a beginner. Alternatively, lightweight third-party solutions like FileZilla Server or Total Commander's built-in features are available. When setting up the server, you need to define the root directory, create users, and assign them permissions (read only, write, and delete).
Connection to such a server is carried out through any FTP client (FileZilla Client, WinSCP) or directly through Windows Explorer by entering in the address bar ftp://server-ip-addressThe key here is a static IP address. If the server computer's IP address changes after rebooting the router, the connection from the laptop will be lost.
Using FTP is especially beneficial if you plan to transfer files not only between your devices but also want to access them remotely over the internet (although this requires setting up port forwarding on your router, which is a separate security issue). The protocol is less "chatty" in terms of service packets than SMB, which in some cases provides a speed advantage on unstable connections.
Let's compare the main characteristics of the methods considered in the table below:
| Method | Difficulty of setup | Speed | Security |
|---|---|---|---|
| Shared folder (SMB) | Average | High | Average (depending on passwords) |
| Exchange with the environment | Low | Medium/High | High (encryption) |
| FTP server | High | Very high | Low (no SSL/TLS) |
| Cloud services | Low | Depends on the tariff | High |
Alternative programs and cloud solutions
If you don't want to mess around with Windows network settings, specialized utilities will come to the rescue. Programs like Resilio Sync, SyncTrayzor (wrapper for Syncthing) or ShareDrop They allow you to transfer files over Wi-Fi in just a few clicks. They use P2P technology, creating a direct connection between devices, bypassing cloud servers (data is not stored on third-party servers), but using the internet only for the initial handshake.
Classic cloud storage services like Yandex.Disk, Google Drive, OneDrive, and Dropbox also shouldn't be discounted. To transfer files from a computer to a laptop, simply upload the file to the cloud from one device and download it on the other. This isn't the fastest method for files larger than 100 GB.
