The use of cloud storage has become a standard, but the need to quickly transfer gigabytes of video, backups or work documents within a home network has not disappeared. A local area network (LAN) provides speeds unavailable for most Internet channels and allows you to work with files directly from your computer’s hard drive.
For owners of mobile devices based on Android this means the ability to view movies stored on a PC or edit documents without first downloading. Shared folder becomes a bridge between stationary storage and smartphone mobility.
The setup process may seem complicated due to the variety of versions of operating systems and file managers. However, understanding the basic principles of the protocol SMB and correctly setting access rights in Windows will solve 90% of potential problems. Let's look at each stage in detail.
Preparing the network environment and Windows device
Before trying to connect the phone to the computer, you need to make sure that both devices are on the same logical network. This is a fundamental requirement for local data sharing to work.
Check that your smartphone and PC are connected to the same one Wi-Fi router. If the computer is connected by cable and the phone via Wi-Fi, make sure that they are on the same subnet (usually these are addresses like 192.168.1.x).
In some cases, isolation of clients on the router can block the connection.
⚠️ Attention: If you have a guest Wi-Fi network configured, devices in it often do not see the main local network. Switch your phone to the main network.
Next you need to find out IP address your computer. This is a unique identifier by which the phone will search for the required resource. Open Command Prompt in Windows by pressing Win + Rtype cmd and press Enter. In the black window, enter the command:
ipconfig
Find the line "IPv4 address" in the section of your active connection. Write down these numbers, they will be useful for setting up the client on your smartphone.
Write down the computer's IP address on a piece of paper or send it to yourself in a messenger, since entering it from the phone's on-screen keyboard is inconvenient, and it's easy to make a mistake in one number.
Setting up a shared folder and access rights in Windows
The most common error - an attempt to connect a folder that physically exists, but does not have network permissions. Simply creating a directory is not enough.
Find the folder you want to open access to, right-click on it and select "Properties". Go to the "Access" tab and click the "Advanced settings" button. Check the box "Share this folder."
Now the critical point is user rights. Click the "Permissions" button. By default, there may be a group "Everyone" with read-only rights. If you need to not only download, but also write files from your phone to your PC, select the group and check the “Full Control” or “Change” box.
Also check the “Security” tab in the folder properties. Make sure that the user you log into Windows as has read and write permissions. Without this, the system may allow you onto the network, but will block access to files at the NTFS file system level.
In modern versions of Windows 10 and 11, sharing settings may be hidden in the Network and Sharing Center. Make sure that the "Enable file and printer sharing" option is enabled in the "Private" network profile.
☑️ Checking Windows settings
Selecting and setting up a file manager on Android
Standard Explorers Smartphones often have reduced functionality for working with network resources. For reliable operation, it is better to use specialized applications, such as CX File Explorer, Solid Explorer or Microsoft LAN Manager.
Let's consider the setup using the example of a popular open source manager. After installing the app, look for the Network section or the plus icon to add a new connection. Select the protocol SMB (sometimes it is called “Local Network” or “Windows”).
In the “Server” or “Host” field, enter the same IP address that you found out through the command line earlier. The port is usually left standard - 445.
Next, authorization will be required. Enter the username and password for your Windows account. Anonymous login works rarely and only with special Windows security settings, so it is better to use your credentials.
After entering the data, click “Login” or “Connect”. If everything is correct, you will see a list of shared folders on your computer.
Solving problems with the SMB protocol and versions
One of the most common reasons for connection failure is incompatibility of SMB protocol versions. Older versions of Android or specific firmware may not support the latest one, which requires encryption, which is enabled by default in Windows 10/11. SMB v3, which requires encryption and is enabled by default in Windows 10/11.
And vice versa: if your phone tries to connect via the old SMB v1, and it is disabled on the computer for security reasons (which is correct), the connection will not be established.
⚠️ Attention: The SMBv1 protocol is vulnerable to ransomware viruses. Never turn it on on your computer all the time. Use it only to temporarily solve problems with old devices.
If the connection fails, try forcing the protocol version in the settings of your file manager on Android. This is usually the "SMB Version" option in the Add Server menu. Try switching from "Auto" to SMB 2.0 or SMB 3.0.
It's also worth checking your Windows Firewall settings. Sometimes it blocks incoming connections for the File and Printer Sharing application.
How to temporarily enable SMB v1 support in Windows (only if all else fails)
Go to Control Panel → apps and Features → Turn Windows features on or off. Find "SMB 1.0/CIFS File Sharing Support" and enable the client and server. Restart your PC. Don't forget to disable this after work!
Connecting via FTP as an alternative method
If fiddling with Windows permissions and the SMB protocol seems too complicated or unstable, there is a great alternative - the protocol FTP. It is easier to set up and often works more stable over the Internet, although it is also effective within a local network.
To do this, you do not need to configure folders in Windows. It is enough to install an application on your phone that turns it into a server, or vice versa - launch an FTP server on your PC (for example, through FileZilla Server) and connect to it from your phone as a client.
But more often, users need the opposite: access PC files from their phone. In this case, install a lightweight FTP server on your computer. Many file managers for PCs have a built-in "FTP Access" function.
The advantage of this method is that it often does not require entering a Windows account password if you configure a specific user inside the FTP server.
Connection methods comparison table
To make it easier for you to choose the appropriate method for integrating your smartphone and computer, we have prepared a comparative table of the main characteristics.
| Characteristics | SMB (Shared folder) | FTP Server | Cloud services |
|---|---|---|---|
| Transfer speed | High (up to 50-100 MB/s) | Medium/High | Depends on the Internet tariff |
| Setting complexity | Medium/High | Low | Very Low |
| Access from outside (not at home) | Requires VPN or static IP | Requires forwarding ports | Works everywhere |
| Security | Depends on the SMB version | Password protection | High (encryption) |
As can be seen from the table, for home use without access to the global network SMB remains the gold standard for speed and ease of integration.
To watch heavy video (4K) within your home network, use only a wired connection or SMB over 5 GHz Wi-Fi to avoid buffering.
Common errors and how to fix them
Even with correct configuration, failures may occur. The error code 0x80004005 often indicates problems with access rights or a disabled network discovery service.
If the phone sees the computer, but asks for a password that does not work, try creating a new local user on the PC with a simple password and giving him rights to the folder. Sometimes domain accounts conflict with the home network.
Another problem is the “sleep mode” of the computer. If the PC goes to sleep, the network adapter may turn off and communication is interrupted. Go to Control Panel → Power Options → Configure power plan → Change advanced power settings. In the "Wireless LAN Adapter Settings" or "Media Settings" section, disable turning off the device to save power.
⚠️ Attention: Windows Settings interfaces may vary depending on the build (Home, Pro, Enterprise) and updates. If you don't find what you're looking for, try searching for options in the Start menu.
Also make sure that the network type in Windows is set to "Private" and not "Public". In a public profile, the system by default hides the computer from other devices.
Frequently asked questions (FAQ)
Why does the phone not see the computer on the network, although both are connected to Wi-Fi?
Most likely, the AP Isolation function is enabled on the router, which prohibits devices see each other. Also check if the network type on your computer is “Public”.
Is it possible to connect to a shared folder via the mobile data (4G/5G)?
Directly - no, since these are different networks. To do this, you will need to set up a VPN server on your home router or use a static “white” IP address from your provider, which is difficult and unsafe for beginners.
Is it safe to store Windows passwords in the file manager on your phone?
Most modern managers (Solid Explorer, CX) encrypt their databases data. However, if your phone is lost, the risk of your PC files being accessed increases. It is recommended to use a complex password on the Android device itself.
How to transfer files faster: via Wi-Fi or cable?
Definitely via cable. Use a USB-C to Ethernet adapter for your phone if it supports this feature, or connect your phone via USB in file transfer mode (MTP), although MTP is often slower and more unstable than SMB over fast Wi-Fi.
