Transferring data between a computer and a smartphone is a routine task that every owner of modern technology faces. USB-The cable is out of hand, lost, or simply causes a connection to fail due to hardware problems with the port. POCO Can use the built-in function FTP-This is a very convenient method, because it doesn't require any software to be installed on the phone, and it works on any local Wi-Fi network.
The MIUI File Transfer Protocol (FTP) technology is simple enough to set up security and network visibility. Using this protocol allows you to access the entire file system of your device directly from Windows Explorer or macOS, turning your smartphone into a full-fledged network folder. The main advantage of this approach is the transfer speed, which is limited only by the bandwidth of your router, and there is no need to physically connect the gadget.
In this guide, we will discuss in detail the process of activating the server, configuring access parameters and solving typical connection problems, you will learn how to properly organize the folder structure for easy access from the PC and what security nuances should be considered when working in public networks. Built-in FTP-Xiaomi server only works on local Wi-Fi network and does not support direct connection via mobile Internet 4G/5G Understanding these basic principles will allow you to effectively manage your media library and documents.
Preparing the network and device for work
Before you start setting up a server, you need to make sure that both devices are in the same information space. This is a fundamental requirement of the protocol: your computer and smartphone must be connected to the same router. If you use separate frequency bands (2.4 GHz and 5 GHz), make sure that the router does not include client isolation, which can prevent their mutual detection.
Check the stability of the connection on the smartphone. For comfortable operation, it is recommended that the Wi-Fi signal be confident, since breaks in the connection will interrupt the copying process of files, and it is also worth turning off the power saving mode for the duration of transferring large amounts of data, so that the system does not “sleep” the network module.
- 📡 Make sure your smartphone and PC are connected to the same Wi-Fi network (the same). SSID).
- 🔋 Turn off the power saving mode on the phone to avoid a connection break.
- 🔒 Check the network type in Windows: it should be “Private” and not “Public».
- 📶 Make sure that the router is not activated isolation AP (clientele).
It is important to consider that corporate networks or guest Wi-Fi in cafes often have strict firewall rules that block the ports used for FTP. At home, such problems usually do not occur unless you have set up complex traffic filtering rules yourself. If the devices do not see each other, first check this aspect.
Activation. FTP-server through a standard conductor
In the Android operating system, which underlies the MIUI shell, the server function is built directly into the regular Explorer app. You don't have to search for hidden engineering menus or download third-party utilities. All the necessary tools are in the file management interface, which is available by default on all devices of the brand.
To start the process, open the File Manager application. In the program interface, find the section responsible for remote connections. It is usually located in the top menu or in the Network tab. By clicking on the FTP icon, you will launch a configuration wizard, which will prompt you to create a new server.
☑️ Launch FTP-server
The system will tell you to choose the type of content you store, and you can access the entire internal drive, or you can access the memory card only. SD, If you have it installed, it's a useful access segmentation feature that hides system files from being accidentally changed from the computer, and then you pick up the storage, and the server will start, and it will appear on the screen. IP-address.
⚠️ Note: Do not use the Anonymous Access feature if you are on a public network, as this will allow any device within the range of the router to access your files without a password.
Once activated, the smartphone screen will display an address of the type ftp://192.168.1.XX:Port. This is the address that will need to be entered in the computer explorer. Note the port number, it may differ from the standard 21, which is an additional security measure implemented by the developers of Xiaomi.
Connecting a computer to a smartphone
Once a server is successfully launched on a mobile device, you need to connect from a personal computer. In Windows, you can do this in several ways that do not require additional software installation. The fastest method is to use the address bar in any Explorer window.
Open "My Computer" or any folder. Click the address bar at the top of the window (where the path to the current folder is written) and enter the address displayed on the phone screen. It is important to enter it in its entirety, including the ftp:// prefix and colon before the port number. Once you press the Enter key, the system will try to establish a connection.
ftp://192.168.1.55:2121If you (set) a login and password when you create a server on your phone, Windows will request credentials, enter them exactly as they are shown on your smartphone screen, and tick “Remember credentials” so you don’t re-enter them every time you connect.
💡
For quick access, create a shortcut on your desktop: after a successful connection in Windows, right-click on the network folder that appears and select “Create a shortcut”.
Once you have successfully logged in, your phone's folders will open in the conductor window, and you can copy, delete and rename files just like you would if you were using a regular flash drive, and the speed of copying will depend on the quality of the Wi-Fi signal and the capabilities of your router's network adapter.
Security and access settings
Data security is a priority when it comes to LAN transmission. Although FTP is an old protocol, implementation in MIUI minimizes risks. The main protection tool is the mandatory setting of a password for connection. Never leave the server open for anonymous access unless you are in a completely isolated test environment.
When you create a server, the system will suggest you set a username and password. Use complex character combinations, especially if your home Wi-Fi network has access to guests, which will prevent unauthorized access to your personal photos and documents even if your Wi-Fi password is hacked.
| Parameter | Recommended value | Safety impact |
|---|---|---|
| Access. | Password only. | High (blocks anonymous) |
| Warehouse | SD-map (if possible) | Medium (isolates system files) |
| Port port | Non-standard (not 21) | Low (scanner protection) |
| Network | Private (Private) | High (hiding from other people's PCs) |
You should also pay attention to the settings of the Windows firewall. When you first connect, the system may ask for permission to network discovery. Allow access only for private networks. If you are in an office or cafe, choose Cancel or Public Network to hide your computer from other network participants.
⚠️ Attention: Protocol FTP Transmit data, including passwords, in plain form. Do not use this method to transmit critical data on public access networks (cafes, airports).
Working with the file system and limitations
When connecting through FTP You get access to the logical structure of files, but not to all system partitions. Android has a strict security policy that limits the access of applications (including built-in ones). FTP-servers) to other system folders, you can work freely with folders DCIM, Download, Music and other user directories.
However, attempts to write files to the root of the system or to folders of system applications can be blocked, which is normal behavior to protect the integrity of the operating system. For the average user who needs to transfer photos, videos or documents, these rights are quite enough.
Why aren't some of the files visible?
When transferring large files (e.g., video to 4K), keep an eye on the process. If the transfer is interrupted in the middle, the file may become corrupted. FTP does not always correctly handle the reconnection to reload the file, so in such cases it is easier to start copying again.
Another important aspect is filename encoding. While current systems are great at UTF-8, transferring Cyrillic-name files to very old operating systems (like Windows XP) can cause problems displaying titles, so rename files using the Latin alphabet before transferring them.
Solving Typical Connection Problems
Despite the ease of setting up, users may encounter a situation where the computer can’t see the phone or the connection is cut off. Most often the problem lies in the settings of the Windows network. If the address is entered with an error “Can’t access the folder”, check whether FTP support is enabled in Windows components (although this is rarely required for a basic connection, sometimes resetting the network settings helps).
A common cause of failures is aggressive power saving. The smartphone screen may go out and the system will turn off the Wi-Fi module to save charge. To avoid this, increase the time before turning off the screen or connect the phone to the charger during transmission.
- 🔄 Restart your router if your devices stop “seeing” each other.
- 📱 Check if the phone is “Flight” or Wi-Fi is turned off.
- 🛡️ Temporarily disable antivirus on PC to check connection lock.
- 🔌 Make sure that the phone does not include traffic saving mode.
⚠️ Note: If you change your router or password from Wi-Fi, address FTP-server (IP-The address will change. You'll have to re-enter the new address in the computer explorer.
And there's also the problem with antivirus software, and some of the security systems on the PC can see incoming software. FTP-connection as a suspicious activity and block it, in which case you need to add an exception to the settings of the firewall of antivirus for local addresses (range) 192.168.x.x).
💡
Connection stability is directly dependent on the quality of the Wi-Fi signal; if there are frequent breaks, try to approach the router or switch to a frequency of 2.4 GHz, which has a longer range.
Alternative methods of data transmission
While FTP is a powerful tool, it’s not always the most convenient solution for fast transfer of a pair of photos. There are other methods in the Xiaomi and Android ecosystem for such cases, such as Mi Share technology, which allows you to instantly share files with other Xiaomi devices and Android smartphones.
You can also use cloud services like Google Drive, Dropbox or the built-in Mi Cloud to work with your computer, which automatically synchronize data but require internet access and have limits on free storage, and FTP benefits from being local and not consuming ISP traffic.
Another option is to use specialized file manager applications with Wi-Fi Transfer support, which often have a friendlier web interest to manage files via a browser. FTP-client MIUI It is the lightest and does not require additions.
