In today's digital world, the need to quickly transfer a ton of photos, video archives, or work documents from one device to another arises daily. Using USB drives for these purposes is becoming an anachronism, especially when both computers are already connected to the same wireless network. Wireless data transmission Saves time and eliminates the need to search for physical media, allowing you to focus on the result rather than the process of connecting cables.
There are many scenarios where this is required local information exchange: moving to a new laptop, setting up a team collaboration in the office, or simply wanting to watch a movie stored on a desktop computer on a portable device in another room. It's important to understand that the speed of such copying directly depends on the bandwidth of your Wi-Fi router and the communication standard it supports. If your equipment operates in the 5 GHz band, the process will be significantly faster than using the crowded 2.4 GHz band.
In this article, we'll take a detailed look at proven methods for organizing data exchange, from built-in operating system functions to specialized software. You'll learn how to set up public access You'll learn how to do it securely and what nuances to consider when working with large amounts of information. Regardless of your Windows version, you'll be able to find the right option for your situation.
Preparing equipment and checking the network
Before configuring the software components, you need to ensure the physical infrastructure is ready. Both computers must be connected to the same router. This is a fundamental requirement, without which local area network (LAN) it won't work even if both devices can see the internet.
Check your connection type in your network settings. Windows may classify your connection as "Public," which automatically blocks other users from discovering your device. For proper operation, you need to change the network profile to "Private" or "Home."
- 📡 Make sure both PCs are on the same subnet (usually the addresses look like 192.168.1.X and 192.168.1.Y).
- 🔒 Disable third-party firewalls during setup if they block local connections.
- 📶 For transferring files larger than 10 GB, it is recommended to use the standard Wi-Fi 5 (AC) or Wi-Fi 6 (AX).
⚠️ Attention: If you're on a corporate or university network, administrators often block ports required for file sharing between clients. In this case, local transfers may be impossible without changing router rules.
Shared Folder Method: The Classic Windows Method
The most reliable and built-in method is to create a shared folder with the correct access rights. This method requires no additional software and operates at the protocol level. SMB (Server Message Block)It is ideal for regular use on a home network.
To begin, select the folder you want to share. Right-click it and select "Properties." Go to the "Sharing" tab and click "Advanced." Check the "Share this folder" box.
Next comes a critical step: setting permissions. Click the "Permissions" button and ensure that the "Everyone" group (or a specific user) has "Read" or "Modify" permissions if you plan to upload and remove files from this computer.
☑️ Setting up a shared folder
Now, to access this resource from another computer, open File Explorer and enter the IP address of the first computer in the address bar. You can find it by launching the command line (cmd) and entering the command ipconfigLook for the line "IPv4 address".
\\192.168.1.45After entering the address, the system may request the login and password of the user account that owns the folder on the first PC. This is a normal security procedure. SMB protocol.
⚠️ Attention: Operating system interfaces and settings menus may vary slightly depending on the Windows version (10, 11) and installed security updates. If you don't see the options described, check the latest Microsoft help.
Using Nearby Sharing
Newer versions of Windows 10 and Windows 11 have a handy feature that works on the principle Apple AirDrop. It allows you to transfer files and links via Bluetooth And Wi-Fi Direct without complex network share setup.
To enable this feature, go to "Settings" (the gear icon in the Start menu). Select "System," then find "Nearby Sharing." Toggle the slider to "On."
Here you can also configure your device's visibility. Two options are available: "Everyone nearby" (visible to all devices within range) and "My devices only" (visible only to PCs signed in with your Microsoft account). For maximum security, it's best to choose the latter option.
The transfer process is simple: simply open the file, click the "Share" button in the app menu, and select the target computer from the list. A notification will appear on the receiving device, requiring confirmation.
- 🚀 The transfer speed is limited by Bluetooth capabilities when detected, but the file flies via Wi-Fi.
- 🔐 Login to the same account is required Microsoft on both devices for the "My Devices" mode.
- 📂 This feature is best suited for transferring individual documents and photos rather than folders.
Why isn't the device in "Share with others"?
A common issue is privacy settings. Go to Settings -> Privacy -> General and make sure discovery is enabled. Also, check that Bluetooth is enabled on both computers, as it's used for the initial handshake.
Third-party utilities for fast transfer (P2P)
If Windows' built-in tools seem too cumbersome or unstable, specialized programs can help. They create a temporary tunnel between computers, often using technology P2P (Peer-to-Peer), which ensures maximum speed.
One of the most popular solutions is the utility Send Anywhere or FeemThe principle is simple: you install the program (or open the web version) on both computers. The application generates a unique six-digit code or QR code.
Enter the code on the receiving device, and the direct data transfer begins. The main advantage of such programs is that they often bypass local network restrictions, even working over the internet if the computers are in different locations but connected to the global network.
| Program | Transmission type | Size limitation | Do you need internet? |
|---|---|---|---|
| Send Anywhere | P2P / Server | No (web: 10 GB) | Just for starters |
| Feem v4 | Local Wi-Fi | No | No (LAN) |
| Resilio Sync | Synchronization | No | Just for starters |
| ShareMouse | Clipboard | Depends on the OS | No (LAN) |
Using third-party software is especially important when you need to transfer files between different operating systems, for example, with Windows on macOS or Linux, where native protocols may conflict.
Setting up an FTP server on your computer
For advanced users who require regular access to files from various devices (including smartphones and tablets), the optimal solution is to deploy FTP servers (File Transfer Protocol)This turns your PC into a full-fledged file storage.
In Windows, you can use the built-in IIS component or download a lightweight server, for example, FileZilla ServerAfter installation, you will need to create a user, assign a password, and specify the root directory to which access will be granted.
Connection is made through any FTP client (for example, FileZilla Client or standard conductor) at the address ftp://computer-IP-addressThis method is good because it allows you to manage access rights more flexibly than a standard shared folder.
Furthermore, the FTP protocol allows for the resumption of interrupted transfers, which is critical when working with unstable Wi-Fi signals and large files. You can be confident that if the connection is interrupted, you won't have to start copying gigabytes of data all over again.
user: adminpass:
host: 192.168.1.45
port: 21
⚠️ Attention: Don't open FTP ports (the default is 21) for access from the external network (the internet) unless you've configured encryption (FTPS) and have a sophisticated security system in place. This could create a security breach in your home network.
Solving speed and visibility issues
Even with proper configuration, users often experience slow copy speeds or computers disappearing from the network list. The problem is often rooted in the network card's power saving settings.
Go to "Device Manager," find your Wi-Fi adapter, open its properties, and go to the "Power Management" tab. Uncheck "Allow the computer to turn off this device to save power." This will prevent the adapter from going to sleep while transmitting.
It's also worth checking whether traffic encryption is enabled at the router level, which can reduce performance, or whether outdated security standards are being used, such as WEP or TKIPA modern network requires a standard. WPA2-AES or WPA3.
- 📉 Low speed is often caused by interference from microwave ovens or neighboring routers on the 2.4 GHz channel.
- 🔄 Restarting the Function Discovery Resource Publishing service in Windows may restore the PC's visibility.
- 🛡️ Antivirus programs often block incoming connections; add an exception for your local network.
FAQ: Frequently Asked Questions
Is it possible to transfer files if one PC is Windows and the other is macOS?
Yes, this is possible. macOS supports the SMB protocol out of the box. In Finder, select "Go" -> "Connect to Server" and enter the IP address of your Windows computer. You will be asked to enter your Windows username and password.
Why is the transfer so slow even though the router is powerful?
The speed may be limited by an old network adapter on one of your computers (for example, only 100 Mbps instead of 1 Gbps) or by high airborne noise. Try switching to 5 GHz.
Is it safe to transmit banking information over a public network?
Transferring files within your home network is relatively safe if you have a strong Wi-Fi password. However, for particularly sensitive data, it's best to use encrypted archives with a password before sending.
How do I find out the IP address of another computer on the network?
On the target computer, open a command prompt and type ipconfigYou're interested in the IPv4 address line. The address can also often be found in the connection status in the system tray.
