Modern home or office local segment Networks often include multiple computing devices that require constant interaction. Data transfer via external drives becomes archaic and slow, especially when working with data volumes exceeding tens of gigabytes. Using a wireless interface Wi-Fi Allows you to organize instant exchange without unnecessary cables if you properly configure the operating system software environment.
In the operating system Windows 10 The network discovery and sharing mechanisms have undergone significant changes compared to their predecessors. It is important for the user to understand the basic principles of the protocol. SMB and resource naming rules to avoid common access errors. Ignoring security settings or network profiles can result in computers simply not "seeing" each other in the list of available devices.
Effective file sharing requires not only technical setup but also an understanding of how network permissions work. SMB protocol version 2 and above is a mandatory standard for secure data transfer in modern Windows 10 builds., as older versions are vulnerable to network attacks. Below, we'll walk you through a step-by-step process that will allow you to create a secure environment for sharing documents, photos, and multimedia.
Checking network settings and connection profile
The first step to successfully organizing data exchange is to correctly configure the network profile. Windows 10 By default, it classifies new connections as "Public," hiding your computer from other devices for security purposes. To work on a home or office network, you need to switch the profile to "Private" to allow device discovery.
Open the Start menu and go to Settings by selecting the gear icon. In the window that opens, select the "Network & Internet" category, then find "Status" in the left menu. Click the "Change connection properties" link under the image of your current network. Wi-Fi.
In the menu that opens, select "Private." This will enable the necessary discovery services and make your PC visible to other authorized users. Without this step, any further manipulation of shared folders will be futile, as the system will block incoming requests.
Setting up sharing options
After changing the network profile, you should activate the resource sharing functionality. The system provides flexible access management tools, allowing you to choose which features will be available to other users. It's important to distinguish between the settings for the current account and guest access.
Return to the Network & Internet menu and find the "Sharing Settings" link (sometimes hidden under "Advanced Settings"). Here you'll see three main profiles: Private Network, Guest or Public Network, and All Networks. Make sure the following options are enabled under "Private (Current Profile)":
- 📡 Enable network discovery (and installation of network devices)
- 📂 Enable file and printer sharing
- 🔒 Allow Windows to manage HomeGroup connections
To simplify access within a trusted home network, you can enable the "Turn on sharing so network users can read and write files in Public folders" option. However, if security is a priority, it's best to leave this option disabled and configure access permissions individually for each folder.
⚠️ Important: Enabling the "Turn off password-protected sharing" option in the "All Networks" section allows you to connect to your resources without entering a username and password. Use this mode only in fully trusted home networks where there are no unauthorized devices.
Creating and sharing a shared folder
The central element of file sharing is the resource that other computers will have access to. You can share any directory on your hard drive, whether it's the root folder of a project or a separate directory for media files. Setting access permissions requires careful consideration to avoid sharing unnecessary information.
Create a new folder or select an existing one, right-click it, and select "Properties." Go to the "Sharing" tab and click "Advanced." Check "Share this folder" and specify a name for the resource as it will appear on the network.
Next, you need to configure user permissions. Click "Permissions" and select a group or a specific user. For full file sharing (read and write), check "Full Control" or "Modify." Be sure to apply the changes by clicking "OK" in all open properties windows.
☑️ Setting up folder access rights
Mapping a network drive and searching for resources
Once the resources are configured, the question arises: how to access them from another computer? Operating system Windows offers several ways to navigate your local network, from automatic detection to manual mapping of network drives for easy, ongoing operation.
The easiest way is to open File Explorer and go to the Network section. All available computers on the local network should be displayed here. If the device isn't displayed, you can try entering its network address directly into File Explorer's address bar using the following syntax: \\ComputerName or IP address.
For permanent use, it's convenient to map the remote folder as a local drive. In File Explorer, right-click "This PC" and select "Map network drive." Select the drive letter from the list, enter the path to the folder (e.g., \\DESKTOP-PC\Share) and check the box "Reconnect at logon".
The system may prompt you for credentials. Enter the username and password for the account on the computer where the folder is located. If the accounts match on both computers, login may occur automatically.
What to do if your computer is not visible on the network?
Try entering the IP address directly. Also, ensure that the "Function Discovery Resource Publishing" and "Discovery Manager" services are enabled on both computers in services.msc.
Comparison of data transfer methods over a local area network
There are many ways to transfer files, and choosing the best method depends on your needs, file size, and security requirements. Understanding the differences between them will help you avoid frustration when working with large amounts of data.
Below is a table comparing the main characteristics of the different approaches to data exchange in the environment. Windows 10:
| Method | Speed | Difficulty of setup | Security |
|---|---|---|---|
| Shared folder (SMB) | High (depending on Wi-Fi) | Average | High (with password) |
| Close interaction | Low/Medium | Low | Average |
| OneDrive (Cloud) | Depends on the Internet | Low | Very high |
| FTP server | High | High | Medium (no encryption) |
The Near Share method built into Windows 10 is convenient for one-time transfers of small files between nearby devices, but it relies heavily on Bluetooth support and can be unstable. For regular work with large archives or video libraries, a classic shared folder remains the undisputed leader in performance.
⚠️ Please note: Wi-Fi data transfer speeds may drop significantly in the presence of interference or when using the 2.4 GHz standard. For transferring files larger than 10 GB, it is recommended to use the 5 GHz band or a cable connection.
Solving common access problems
Even with proper configuration, users often encounter access errors such as "No access," "Incorrect username or password," or computers not appearing on the network at all. These issues are usually rooted in service configuration details or antivirus software.
One common cause is a disabled sharing service. Click Win + R, enter services.msc and find services related to SMB and discovery. Ensure that the Function Discovery Resource Publishing and Discovery Manager services are running and have the startup type set to Automatic.
It's also worth checking your firewall settings. Sometimes third-party antivirus programs block incoming connections, deeming them suspicious. Try temporarily disabling the firewall or adding an exception for your private network to see if the problem goes away.
If the system consistently returns an error when entering a password, try creating a new local user on the receiving computer with a simple password (without special characters) and granting access rights to that user. This often circumvents issues with domain security policies or complex Microsoft Account passwords.
Frequently Asked Questions (FAQ)
Is it possible to transfer files between Windows 10 and macOS or Linux?
Yes, this is possible. macOS and Linux support the SMB protocol. On a Mac, use Finder -> Go -> Connect to Server and enter the Windows PC's address. On Linux, use a file manager (Nautilus, Dolphin) and select "Connect to Server," specifying the SMB protocol.
Why is the Wi-Fi transfer speed very low (less than 1 MB/s)?
Slow speeds may be caused by using an older Wi-Fi standard (802.11g/n), being too far away from the router, interference from neighboring networks, or operating in the 2.4 GHz band. Also, check if your antivirus software is restricting your network activity.
Do computers need to be in the same workgroup?
By default, Windows uses the WORKGROUP workgroup. For stable operation on a home network, it is advisable to have all computers set to the same workgroup name. You can check this in System -> Advanced system settings.
How to deny access to a specific folder to a specific user?
In the folder properties, on the "Security" tab, select the user and check the "Deny" box for the desired actions, or simply remove them from the list of users with access. Explicitly denying them takes precedence.
