Xiaomi smartphones today have a huge amount of internal memory, but this is often not enough to work with multimedia. Users actively use cloud storage or connect external drives via USB-OTG. However, there is a more flexible and reliable way to organize access to data – the NFS technology (Network File System), which allows you to turn your phone into a full-fledged terminal for working with files on a remote server or home computer.
Unlike the standard protocol. SMB, which is often found in Windows, NFS This is especially true for owners of low-end models of the Redmi or Poco series, where every megahertz of the processor is accounted for. 4K, Music without buffering and real-time documents.
The process of integrating this technology into the MIUI or HyperOS shell has its own security nuances related to Android. You will not only need to configure the server part correctly, but also choose a compatible client application. In this article, we will discuss all the stages of connection, from choosing software to debugging hidden network settings.
Principles of network storage on Android
Technology NFS It was developed in the 80s by Sun Microsystems and has since become the de facto standard for Unix-like systems. In the context of mobile devices, Android acts as a client that requests access to the file system of a remote machine. NAS-storage, router USB-port or regular PC running Linux.
The main advantage is the transparency of access. For a smartphone operating system, the connected folder looks like part of the local memory. You can open video files directly in the player without downloading them beforehand. This saves space and speeds up the work with content. However, unlike Windows, where support is built in, Xiaomi requires a third-party file manager with the corresponding plugin.
⚠️ Attention: Protocol NFS Do not use it on public Wi-Fi networks without additional protection, such as VPN tunnel.
Modern versions of Android strictly control the access of applications to the network and the file system. When you first try to connect, the system can request permission to access the local network. If you use a dual-band router, make sure that the smartphone and the server are in the same subnet, preferably at 5 GHz for maximum bandwidth.
💡
Use static. IP-address NFS, not to reconfigure the connection every time the router gives a new address to the DHCP.
Choosing the Right File Manager
Xiaomi’s standard Files Explorer has limited functionality and often does not support direct mounting. NFS-So the first step is to install a specialized application, and the market leader is already MiXplorer, which has built-in support for all popular protocols.
The alternative is ES Explorer (older versions) or CX File Explorer, which are user-friendly and run on the shells of MIUI 12, 13, 14 and the new HyperOS. It is important to choose versions of applications that are regularly updated, as Google changes security policies, blocking access to the network in older builds.
- 📱 MiXplorer – the most powerful combine with support for plugins, ideal for advanced users.
- 📂 CX File Explorer is lightweight, fast, with modern design and excellent support SMB/NFS.
- 📀 Owlfiles is a specialized multimedia client, able to mount discs as local.
- 🛠 Solid Explorer is a paid, but very high-quality manager with encryption and cloud synchronization.
When installed from Google Play, some features may be cut down due to store policies, such as access to the root file system or specific codecs. Full functionality often requires downloading a version from the developer’s official website or from alternative repositories like F-Droid.

Preparation of the server part and the network
Before you grab the phone, you need to make sure the source of the files is ready to go. NAS from Synology or QNAP, setup NFS It's usually in the File Services section, where you need to activate the protocol and write permissions for specific folders. IP-address of your smartphone or allow access to all hosts on the local network.
Linux users will need to edit the configuration file /etc/exports. It adds a path to the shared directory and access parameters. /media/data 192.168.1.0/24(rw,sync,no_subtree_check) The service will be re-launched by the exportfs team after the changes. -ra.
| Parameter | Importance for the home network | Description |
|---|
| IP Server | 192.168.1.X | Static server address |
| Port | 2049 | Standard NFS port |
| Access | Read/Write | Reading and writing rights |
| Security | sys | Type of authentication (usually) |
Owners of Keenetic or Asus routers with connected USB-You need to go to the web interface of the administrator «USB-Applications or Network Environments are activated NFS.

If the server requires authentication (password), enter the user's data. NFS open-access IP, So you can leave the login fields blank. Click OK or Save. If all the options are entered correctly, a new icon will appear in the Explorer side menu with the name of your network. You click on it and you will mount the partition. The files are now available for viewing, copying and editing. Read speed should be comparable to the speed of your Wi-Fi connection. ⚠️ Note: If you lose communication with the server (for example, the router rebooted), the file manager may freeze when you try to access the server. In such cases, it helps to force the application to stop through the Android settings. MIUI It's known for its aggressive power saving system, which can kill the background processes of the file manager. → Annexes → All applications, find your explorer, and select Autostart. Allow it to run in the background and remove battery consumption restrictions. Also, check your network settings. Go to Settings. → Wi-Fi → Click on your network. → Settings IP. Make sure you are “static” or «DHCP», But most importantly, it does not include isolation of customers (AP Isolation), if it is controlled from a phone, this feature prevents devices on the same network from seeing each other. To improve security, you can configure access on the server only for a specific purpose. MAC-Addresses of your Xiaomi smartphone. You can find it in the settings. → The phone. → This will protect your network from accidentally connecting neighbor devices if they end up on the same subnet. 🔒 Enable a firewall on the router for incoming connections from the external network. 📱 Use guest Wi-Fi network for IoT devices, separating them from the main files. 🔐 Change the router administrator passwords regularly and NAS-storage. 🚫 Turn it off. WPS The common problem is the error "waiting time has expired" or "Access denied" The first usually indicates network problems: Check if the phone is "seeing" by the server via the ping command (available in some advanced managers or through the terminal). The second one is about incorrect server-side rights or port locks (>4GB). If the file system on the server is formatted in FAT32, You can’t write a larger file, even if you have an exFAT or a larger file. NTFS. Make sure the server folder uses a modern file system that supports large files. If the video stutters when playing, try to lower the bitrate of the stream in the player settings or switch to a wired connection via a USB-Ethernet adapter for Xiaomi. Wireless standard Wi-Fi 5 (802.11ac) It is necessary for comfortable viewing 4K So, why is it that files are not being written to the server? NFS for yours IP-address or user has read-only rights. /etc/exports on Linux or the settings of the sharing on NAS, Add rw (read-write) and make sure there is free space on the disk. Can I use it? NFS Is it technically possible, but it's not recommended without VPN. Direct port crossing NFS (2049) Internet is dangerous because the protocol does not have built-in authorization (SSH) How do you speed up copying? Make sure you're using 5 GHz. Check if your neighbors are congested with Wi-Fi. In your router settings, try changing the channel width to 40 or 80 MHz. Also, the speed can rest on the write speed of the disk itself on the server (especially if it is an old one). USB 2.0 drive? Does my Xiaomi support NFS - No Root? NFS At the application level, no superuser rights (Root) are required. All modern file managers are user-friendly. Root may only be needed if you want to mount a network drive as part of the system's local file system, but for normal use, it's redundant. What if you lose your connection after a MIUI update? Android security updates often change the rules of network access. Re-authorize the application when you first start. Check if your static IP settings have reset. At the very least, try to delete your Wi-Fi network profile and reconnect by entering your password.
