Sharing files between devices within a home or office network is no longer a complex task requiring flash drives or external drives. Modern operating systems allow for quick access to data using only the capabilities of a local network built over Wi-Fi routerThis is especially relevant for multimedia systems, document collaboration, or backing up information to another PC without using cables.
The setup process may seem complicated at first glance, but if you break it down into logical steps, everything becomes intuitive. You won't need any special software—all the necessary functionality is already built in. WindowsThe main thing is to properly configure security settings and network discovery so that computers can "see" each other in the wireless space.
In this article, we'll detail the process for creating shared folders, explore the nuances of working with passwords and access rights, and address common user issues. Following these instructions will help you establish a stable data connection between a laptop and a desktop PC, or between two workstations.
Preparing the network infrastructure and checking the connection
The first and most important condition for successful shared access is that both computers are on the same local network. This means that the devices must be connected to the same Wi-Fi router, regardless of whether they're using a wireless connection or an Ethernet cable. If one computer is connected to the guest Wi-Fi network and the other to the main network, they won't be able to exchange data.
Make sure the network type in your system is set to "Private" and not "Public." By default, Windows hides your computer from other devices by blocking necessary protocols when using a public profile for security reasons. You can check this by opening Network and Internet settings in Control Panel.
It's also worth checking the visibility of your devices. Open File Explorer and go to the "Network" section. If you see your computer and possibly other devices (printers, media boxes), then the basic setup is correct. Missing devices often indicate that services are being blocked by an antivirus or firewall.
- 📡 Both computers must be connected to the same router.
- 🔒 Network type must be set to "Private" mode.
- 👁️🗨️ Network discovery is enabled in Windows settings.
Setting up sharing options in Windows
After confirming the physical connection, you need to enable the appropriate software permissions. Go to Control Panel, select Network and Sharing Center, and click Change advanced sharing settings. This is where the key switches for controlling your PC's visibility are hidden.
In the "Private" (current) profile, you must enable network discovery and file and printer sharing. These actions allow the operating system to respond to requests from other devices on the network and broadcast information about available resources. Without these options enabled, the computer will be "invisible" to neighboring Wi-Fi users.
⚠️ Attention: Enabling sharing in the "All Networks" profile (Guest or Public) can make your files accessible to others if you're in a cafe or office. Always check the active profile before changing settings.
Pay special attention to the "All Networks" section. Here you'll find an important option called "Password-protected sharing." If enabled, anyone attempting to access your shared folder will be required to enter the username and password for your computer account. Disabling this feature will simplify access, but will reduce security.
Creating and sharing a folder on the first computer
Now let's move on to creating the resource you plan to share. Create a new folder in a convenient location (for example, on drive D or at the root of drive C) or select an existing one. Right-click it and select "Properties," then go to the "Sharing" tab.
Click the "Advanced Settings" button and check the "Share this folder" box. The "Share Name" field will default to the folder name, but you can change it to anything you want network users to see. This is useful if you want to hide the actual directory structure.
Next, you need to configure permissions. Click the "Permissions" button and select the "Everyone" group (or a specific user if you're working on a domain or with specific accounts). Here, you can grant or deny full access, modify, or read-only permissions. For file-sharing applications, "Read" and "Modify" permissions are usually sufficient.
Quick access path to settings:
Folder Options → Sharing Tab → Advanced Settings → Permissions
It's also important to check the "Security" tab in the folder's properties. Even if you've granted access through the "Sharing" tab, NTFS system permissions may be blocking access. Ensure that "Everyone" with read and execute permissions is listed in the Groups and Users list.
- 📂 Create a folder or select an existing one to share.
- ⚙️ Use "Advanced Setup" for flexible control.
- 🔑 Set "Full Control" or "Modify" permissions for users.
Finding a network path and connecting on a second computer
Once the folder is shared, move on to the second computer. The most reliable way to access shared files is using a network path. This consists of two backslashes followed by the IP address of the first computer or its network name, for example: \\192.168.1.5 or \\COMP-NAME.
You can find out the IP address of the first computer by launching the command prompt (cmd) and entering the command ipconfigWe're interested in the "IPv4 address" line. By entering this address into the address bar of File Explorer on the second PC, you'll see a list of all shared folders. If the system prompts you for credentials, enter the username and password from the first computer.
☑️ Checking the connection to a shared folder
For easy, permanent use, you can map a network folder as a separate drive. In File Explorer, click "This PC," then select "Map network drive" from the menu. Select any available drive letter (e.g., Z:) and enter the path to the resource in the "Folder" field. Check "Restore at logon" to make the drive appear automatically after a reboot.
⚠️ Attention: If you receive an "Unable to access" error when connecting, try using the IP address instead of the computer name. DNS issues often interfere with name resolution on home networks.
Troubleshooting common errors and visibility issues
Despite standard procedures, users often encounter a situation where computers cannot see each other. One of the most common causes is a disabled "Function Discovery Resource Publishing" service. Check its status in the service. services.msc and make sure it is running and running in automatic mode.
Another common issue is blocked ports by antivirus software or Windows Firewall. If you're confident your home network is secure, try temporarily disabling the firewall to test. If the folder becomes accessible after this, you'll need to add an exception rule for the SMB protocol (ports 139 and 445).
It is also worth paying attention to the work of services Function Discovery Resource Publication And SSDP DiscoveryIn new versions of Windows 10 and 11, they are often disabled by default, which hides the computer from the list of network devices, even if IP access works correctly.
| Problem | Probable cause | Solution |
|---|---|---|
| Access Error 0x80070035 | Invalid path or name | Check syntax \\ |
| Password prompt in a loop | Mismatch of credentials | Disable password protection or create identical logins |
| The computer is not visible on the network | Network discovery is disabled | Enable in Network and Sharing Center |
| Slow copy speed | Weak Wi-Fi signal | Move closer to the router or use 5 GHz |
Secret registry setting for older networks
If all else fails, you can try changing the LocalAccountTokenFilterPolicy registry entry, setting its value to 1. This often helps when connecting between different versions of Windows, but requires caution.
Security Issues and Wi-Fi Speed Optimization
When setting up shared access, it's important to balance convenience and security. Open, password-less access is convenient for a home network, but it's strictly not recommended if your Wi-Fi is accessible to strangers. An attacker within range of your router could theoretically access your files.
Wi-Fi data transfer speeds directly depend on the wireless standard and signal strength. If you plan to transfer large amounts of data (4K movies, game archives), using the 2.4 GHz band may become a bottleneck. Switching to 5 GHz will significantly increase channel throughput.
Regularly check the list of connected devices on your router. Unexpected "guests" on your network can not only steal traffic but also attempt to scan open ports. Changing your Wi-Fi password to a complex one and using WPA3 (or WPA2) encryption are basic measures to protect your local environment.
Frequently Asked Questions (FAQ)
Is it possible to create a shared folder between Windows 10 and Windows 7?
Yes, this is possible, but it requires additional configuration. Windows 10 disables the SMBv1 protocol by default, which is often used in Windows 7. However, enabling SMBv1 is unsafe. It's best to configure both computers to use SMBv2/3 by updating Group Policy settings and enabling support for older protocols only when absolutely necessary.
Why is my password always rejected when I enter it?
A common cause is a blank account password. Windows prevents network logon for users without a password for security reasons. Create a password for your account or temporarily allow logon for accounts with blank passwords in the local security policy (this is not recommended).
How do I disable a shared folder if I no longer need it?
Return to the folder properties on the first computer, go to the "Sharing" tab, click "Advanced," and uncheck "Share this folder." Once these settings are applied, the folder will only be accessible locally.
Does a router affect file transfer speed?
Yes, directly. The speed is limited by the slowest link in the chain. If your router only supports the 802.11n standard (150 Mbps), files won't transfer faster than that, even if you have gigabit internet and fast computers.
