Owners of Xiaomi, Redmi and POCO smartphones often face the need to quickly transfer large amounts of data between the phone and the computer without the use of cables. The NFS (Network File System) protocol, or its more common Android analog SMB, allows you to turn a device into a full-fledged network drive, which allows you to view movies, edit documents or make backups right in the network environment.
However, the standard security settings for the MIUI and HyperOS shells hide these features from inexperienced users by default. To activate the ability to access the file system from the outside, you need to perform a number of specific actions in the settings menu and file managers. In this article, we will discuss in detail how to open access, which applications to use and how to avoid typical connection errors.
It is important to note that the term "open" NFS" Android is often confused with server inclusion. SMB creation FTP-server, as native support for the server part NFS And we're going to look at all the current ways to network data that work consistently on the Chinese manufacturer's modern devices.
Understanding Network Protocols on Android
Before you start setting up, it’s important to understand the terms. When you talk about network access to files on Xiaomi, most often you mean one of three protocols: SMB, FTP or WebDAV. NFS protocol has historically been used in Unix systems and requires specific server applications on Android, whereas SMB is built into most conductors out of the box.
The Server Message Block (SMB) is the most convenient solution for integrating a smartphone into a Windows home network, which allows you to see your phone as a network drive in My Computer, and it provides high transfer speeds and supports large files, which is critical for a media library.
The alternative is FTP, which is easier to set up but less functional in terms of access rights. The choice of method depends on your goals: for automatic backups, FTP is better for you, and for comfortable watching video from a TV or PC, SMB is better.
⚠️ Note: When you open your network, your smartphone becomes visible to other devices on the local network. Make sure you are connected to a secure home Wi-Fi, not a public network at a cafe or airport.
Modern versions of Android have strict background restrictions, which means that for network storage to work properly, you need to configure permissions and exclude the application from power saving mode.
Device and network preparation
The first step before you open files is to properly prepare the network infrastructure: both devices — a Xiaomi smartphone and a computer (or TV) must be on the same subnet, which means that they must be connected to the same router.
It also needs to be recorded. IP-Smartphone address: In dynamic mode, the address may change after rebooting, causing the connection to break. IP in the router settings or manually prescribe it in the Wi-Fi settings on the phone itself.
- 📶 Make sure both devices are connected to 2.4GHz or 5GHz Wi-Fi (it is important to keep client-isolated guest networks out of service).
- 📱 Check that your smartphone has Wi-Fi and mobile data on (for some system checks).
- 🔋 Charge the device to at least 40% as active network activity consumes the battery quickly.
In the Wi-Fi settings on Xiaomi, go to your network details and select Settings IP". Change the meaning of c DHCP Static. Write down the current one. IP-address, gateway and DNS, to re-register them, saving the current values, or simply remember the address that the router gave.
Use of the built-in file manager
The easiest way to open network storage on Xiaomi does not require installing third-party software. MI File Manager has a hidden function of creating FTP-The server, which is often mistakenly called NFS-access due to similarity of the final result.
To activate, open the Files app and go to the Files tab (not Categories or Recents). At the top of the screen, find the menu icon (three bars or dots) and select Remote Management or Network Access.
☑️ Checking before starting the server
After turning on, you will see the message "Successfully connected" and the address of the view ftp://192.168.1.XX:XXXX. This address should be entered in the address bar of the conductor on the computer. It is important that the built-in server only works while the application is open or the phone screen is active unless an exception is configured.
Why is FTP slower than SMB?
If you need a protocol, SMB And so when you can access your phone folders as a network drive, it's harder to do that with built-in tools. SMB-protocol over the Android file system.
Configuring through third-party server applications
To fully implement the idea of "opening" NFS/SMB" It is recommended to use applications such as WiFi File Transfer, Portal or Solid Explorer with a plugin. LAN. These tools allow you to configure a permanent server with authorization.
Consider an example of setting up a customized Solid Explorer based combine, and after installation, go to the application settings and find the Servers or LAN section. You need to activate the SMB server. You need to specify the username and password that will be requested when you connect to your PC.
| Parameter | Default value | Recommended value | Description |
|---|---|---|---|
| Port port | 445 or 139 | Any free (>1024) | Port number for connection |
| Anonymous access | Off. | Off. | Allows entry without password (unsafe) |
| Access to the root | Prohibited. | If necessary, | It gives you access to the entire file system. |
| Coding | UTF-8 | UTF-8 | To correctly display Russian file names |
After running the server in the application, on the computer in the Explorer, select "Connect network disk." Enter the address in the format \\IP-Address/share. If the system requests credentials, enter the data specified in the application.
Some users prefer to raise the full NFS-server via Termux terminal emulators, but this requires Linux command line skills and root rights, which goes beyond basic configuration.
Solving visibility and access problems
A common problem after a user tries to open access is that the computer can't see the phone or the connection is reset, and 90 percent of the time, the MIUI security system is to blame, which kills background processes to save energy.
You need to go to the battery settings, find the running application server and set the "No restrictions" mode, and it is also worth fixing the application in the menu of running tasks (swipe down the application card and press the lock).
⚠️ Warning: Antivirus programs or firewalls on the router can block ports used for the purpose of SMB (Check the security settings of your router.
If the connection error occurs "Incorrect login or password", try in the settings SMB-Server on the phone to enable support for older versions of the protocol (SMBv1), Windows 10 and 11 by default disable this protocol, but in home networks without Internet access, this is permissible.
Another reason could be the wrong subnet mask. Make sure that the first three digits are on your PC and phone. IP-addresses are the same (for example, 192.168.1.X), The last one is different.
Alternative methods of transmission and synchronization
If the NFS or SMB tinkering seems too complicated, there are more modern methods, such as Mi Drop (now ShareMe) that allows files to be transferred over Wi-Fi Direct without a router, creating a direct access point.
For automatic synchronization of photos and documents, cloud services built into the Xiaomi Cloud ecosystem or third-party solutions like Google Photos and Yandex Disk are great. They work in the background and do not require manual IP-address configuration.
💡
Use the application "Mi PC Suite" or its analogues for wireless file management, if you do not need a network disk, but just convenient uploading photos.
However, it is network access via SMB/FTP that gives you the maximum flexibility: you can mount your phone’s memory like a regular drive, work with video editors directly, or use your phone as a cheap network storage (NAS) for torrents.
For advanced users, the path is open through ADB (Android Debug Bridge) with commands you can throw ports and organize tunnels, but this requires a PC and a Xiaomi USB Driver installed.
Safety and optimization of work
A permanently open port on your smartphone is a potential vulnerability. If you use your phone as a server regularly, make sure to set a complex password in the server application settings. Don't rely on Wi-Fi router protection as the only barrier.
Check the list of connected clients in the server app regularly. If you see an unfamiliar device, change your password immediately and recheck your router's settings for filtering. MAC-address.
💡
The optimal balance between convenience and security is to turn the server on only for the time necessary and use a static IP with password protection.
Also, watch the temperature of the device. When you actively transfer large files, the processor and Wi-Fi module heat up. Remove the case if it interferes with heat transfer, and do not cover the phone while you are working.
In conclusion, “open NFS" Xiaomi is a networking process that turns your gadget into a powerful data tool. FTP, sideways SMB-The server or cloud technology depends on your specific tasks and level of technical training.
