Transferring data between computers on a local network has become less of a challenge with the advent of modern operating systems. You no longer need to search for a USB flash drive or connect an external hard drive if both devices are within range of the same wireless network. Transfer speed Wi-Fi often exceeds the capabilities of Bluetooth, and the convenience lies in the absence of unnecessary wires.
There are many ways to organize information exchange, from built-in Windows and macOS features to specialized software. The choice of a specific method depends on your goals: whether you need to transfer a single document or set up permanent access to a media library. In this article, we'll discuss the most effective workflows that will help you exchange files in a matter of seconds.
The main requirement for all the methods described below is that both laptops must be connected to the same access point. This could be a home router or a mobile phone internet connection, as long as the devices' IP addresses are on the same subnet. Wi-Fi Direct allows you to transfer data even without a router, creating a direct connection between devices.
Setting up a shared folder in Windows over a local network
The most classic and reliable method, requiring no additional software, is to use the built-in shared folder mechanism. This method is ideal for office work or regularly exchanging large amounts of data between desktop workstations. First, ensure that network discovery is enabled on both computers.
Go to the control panel and find the section Network and Sharing CenterIn the left menu, select "Change advanced sharing settings." Here, you'll need to enable "Turn on network discovery" and "Turn on file and printer sharing" for the current network profile (usually a "Private" network).
After configuring your network settings, select the folder you want to share with other users. Right-click it, select "Properties," and then go to the "Sharing" tab. Click the "Sharing" button and add the user "Everyone," assigning them the necessary permissions (read or read and write).
- 📂 Open File Explorer and enter in the address bar
\\Computer IP addressto access the resources of another laptop. - 🔐 When prompted for a password, enter the credentials of the user logged in to the remote computer.
- 🖥️ For convenience, you can right-click on the network folder and select "Mount as network drive" so that it appears as a separate drive in "My Computer."
⚠️ Warning: If computers are in different domains or workgroups, authorization issues may occur. Ensure computer names are unique and do not contain Cyrillic characters, as older SMB protocols may incorrectly handle Russian characters in hostnames.
Using Nearby Share in Windows 10 and 11
In newer versions of the operating system, Microsoft has implemented a convenient tool called Nearby Sharing. This mechanism uses a combination of Bluetooth for device discovery and Wi-Fi for direct data transfer, providing high speed and ease of use, similar to AirDrop in the Apple ecosystem.
To activate the feature, open the system settings via the menu Start → Settings → SystemFind the "Nearby Sharing" section and toggle the slider to "On." You can also adjust the visibility here: select "Everyone" if you want to share files with any device within range, or "Just My Devices" if both laptops are linked to the same Microsoft account.
The transfer process is as simple as possible: simply right-click the file you want to send and select "Share" from the context menu. The system will automatically search for available devices. When a notification appears on the target laptop, all you have to do is accept the request to receive the data.
It's important to note that this method works most reliably when both devices are running the same version of Windows or similar builds. The encryption protocol ensures the security of transmitted data, but when working in public places (cafes, airports), it's best to use the "Only My Devices" visibility mode.
Organizing transfers between Windows and macOS
Cross-platform data sharing is often challenging due to differences in file systems and security protocols. However, using standard SMB protocols, you can easily establish communication between a Windows PC and a MacBook laptop. This allows you to create a unified media library or work environment without purchasing an expensive NAS server.
On the Windows side, you need to create a shared folder as described in the first section, but with one important addition. In the advanced sharing settings, enable the "Turn off password-protected sharing" option (only for trusted home networks!) so that the Mac can connect without complex account management.
On macOS, open Finder and from the menu at the top, select Go → Connect to Server (or click Cmd + K). In the address field, enter the IP address of the Windows machine in the format smb://192.168.1.XXThe system will prompt you for your Windows account username and password, after which it will mount the network folder as an external drive.
| Parameter | Windows (Source) | macOS (Client) |
|---|---|---|
| Protocol | SMB/CIFS | SMB (via Finder) |
| Addressing | IP address or PC name | smb://IP address |
| Access rights | Read/Write | Depends on Windows settings |
| Speed | Depends on the router | Depends on the router |
⚠️ Note: macOS may block connections to older versions of the SMB protocol (SMBv1), which are sometimes used in older Windows versions (XP, 7), by default. It is recommended to use SMBv2 or SMBv3 by enabling them in Windows Features, as SMBv1 has security vulnerabilities.
What to do if Mac can't see Windows on the network?
Often, the problem lies in Windows Firewall settings. Try temporarily disabling the firewall to test. If that helps, add an exception rule for "File and Printer Sharing" in the Defender Firewall settings. Also, make sure the "Private" profile is selected in the network settings, not "Public."
Third-party utilities for fast transfer (Send Anywhere, Shareit)
If fiddling with network settings and access rights seems too complicated, specialized applications will come to the rescue. Programs like Send Anywhere, Feem or LocalSend create their own secure connection over the local network, ignoring the operating system's restrictions.
The operating principle of these programs is the same for all: you install the client on both laptops (or use the web version on one of them). The application generates a unique 6-digit key or QR code. Enter this key on the receiving device, and the connection is established. The transfer speed is limited only by the capabilities of your Wi-Fi router.
The main advantage of such solutions is their cross-platform nature and independence from OS versions. You can transfer a file from Windows 11 to a MacBook running macOS Ventura or even to a Linux machine without setting up SMB or NFS. Furthermore, many of these utilities support internet transfers if a local network is unavailable.
- 🚀 LocalSend — a completely free, open-source solution that does not require the Internet to operate, only a local network.
- 🌐 Send Anywhere — allows you to transfer files up to 10 GB in size without registration, but with a link lifetime limitation (10 minutes).
- 📱 Feem — Works great in offline mode (via Wi-Fi Direct), creating its own network if the router is unavailable.
Cloud storage as an intermediate link
Cloud services such as Google Drive, Yandex.Disk or DropboxAlthough this method technically uses an internet connection rather than direct Wi-Fi transfer, it is often faster and more reliable when the connection between devices is unstable. The file is uploaded to the server and instantly available on the second laptop.
This method is ideal if your laptops are physically separated but connected to the same account. Synchronization happens in the background. You simply copy a file to the cloud storage folder on the first laptop, and it automatically appears on the second.
However, if the internet connection is limited and the files are tens of gigabytes in size, this method is inferior to local transfer. In this case, the cloud is used more as an archive than a transport. A stable internet connection is required, which is not always available.
⚠️ Please note: When using cloud services, be aware of disk space limits. Free plans are typically limited to 5-15 GB. For transferring large amounts of data (such as a system backup), it's best to use a local network or an external SSD.
Diagnosing network problems and bottlenecks
Even with proper configuration, transfer speeds can be disappointing. Often, the bottleneck isn't software, but rather the wireless network's performance. If your router only operates in the 2.4 GHz band, the actual speed is unlikely to exceed 3-4 MB/s, which is significantly slower than a wired connection.
To achieve maximum speeds (20-50 MB/s and higher), both laptops and the router must support the standard. 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6) and operated in the 5 GHz band. This frequency range has less interference from neighboring networks and household appliances.
It's also worth checking your network card's power settings. Windows may automatically disable the adapter to save power, which can cause connection drops when transferring large files. In Device Manager, under the Wi-Fi adapter properties, on the "Power Management" tab, uncheck "Allow the computer to turn off this device."
☑️ Checklist for maximum speed
If the speed is still slow, try temporarily disabling your antivirus software. Some security suites scan every network packet passing through, which creates significant latency. Once the transfer is complete, be sure to re-enable your antivirus.
Frequently Asked Questions (FAQ)
Is it possible to transfer files via Wi-Fi without a router?
Yes, it's possible. In Windows 10 and 11, you can create a mobile hotspot (share Wi-Fi from your laptop) that a second laptop can connect to. Many programs (Feem, Shareit) can also create a direct Wi-Fi Direct connection between devices without an access point.
Why is the network transfer speed only 1-2 MB/s?
Most likely, you're using the 2.4 GHz band, which is heavily polluted, or one of your devices is connected via the 802.11n (Wi-Fi 4) standard with a single antenna. Distance to the router and the presence of obstacles (such as walls) can also play a role. Switching to 5 GHz solves the problem in 90% of cases.
Is it safe to enable folder sharing on public Wi-Fi?
Absolutely not. Always select the "Public" network profile in cafes or airports. In this mode, Windows blocks incoming connections and hides your computer from other network users, protecting your data from intruders.
How to transfer a file larger than 4 GB if the file system is FAT32?
The problem isn't with the transfer method, but with the file system of the flash drive or disk if you're using them as an intermediate storage device. FAT32 doesn't support files larger than 4 GB. Format the disk to NTFS or exFAT, or use a network transfer, which doesn't have these limitations.
