Transferring files from smartphone to computer seems like a simple task, but Xiaomi Redmi owners often face unexpected difficulties: the phone is not defined as a drive, drivers refuse to install, MIUI blocks access to folders. In this article, we will discuss all working methods for transferring data over USB, including hidden MIUI settings, bypassing typical errors and alternative options for cases where the cable does not help.
Xiaomiβs aggressive security policy in MIUI firmware, which by default restricts access to the file system via USB, protects against viruses but hinders users, shows how to disable these restrictions without risking data, and also tells about little-known features like PTP mode for photos or adb pull for advanced users.
If youβve tried to connect a Redmi Note 10 or Redmi 9A to a PC and youβve seen βDevice not recognized,β donβt be quick to blame the cable. 80% of the time, the problem lies in the phoneβs settings or Windows drivers. Next, step-by-step instructions with illustrations (for key steps) and a USB compatibility table for different Xiaomi models.
1. Preparation of the smartphone: turn on the file transfer mode
Before you connect Xiaomi Redmi to your computer, you need to activate file transfer mode (MTP) in the phone settings, without which Windows will see the device as an "unidentified" or charging battery.
Open the Settings. β Connection and sharing β USB-Connection. Select "File Transfer" here" (MTP). If this is not the case, then your version MIUI Then you'll do it like that:
- π Connect your phone to your PC with the original cable (Chinese no-names often donβt support data transfers).
- π± Unlock the Xiaomi screen β without it, the connection is not activated.
- π In the notification panel will appear notification "USB To transfer files." Tap it and select File Transfer (MTP).
- π If there is no item, go to Settings β About the phone, 7 times tap on the version MIUI, To turn on Developer Mode. Then go back to Additional Settings. β Developer settings and activate Debugging by USB.
Important for Redmi with MIUI 13+: in some regional firmware, the MTP item is hidden due to security policy. To return it, turn off Data Protection in Settings β Privacy (reboot required).
2. Computer setup: drivers and USB modes
Even if Xiaomi is set up correctly, Windows may not recognize it because of a lack of drivers, especially for Windows 7/8 users or those who have recently reinstalled the system.
Follow this algorithm:
- Connect your phone to your PC. If a notification appears "Device not recognized" - right-click on it β Update the driver β Automatic search.
- If you do not find it automatically, download the official Xiaomi drivers (the βToolsβ section) and install them manually through Device Manager.
- Redmi with MediaTek processors (e.g. Redmi 9A) will require an MTK USB Driver.
If the drivers are installed, but the phone is still not visible as a drive:
- π Reboot both devices.
- π Try another one. USB-port (preferably) USB 3.0 blue).
- π₯οΈ Windows. 10/11 Turn off fast loading in power supply parameters.

3. Alternative USB modes: PTP, MIDI and ADB
If MTP doesn't work (a common problem on MIUI 14), try other protocols.
| Regime. | What's the point? | Limitations | Redmi models with support |
|---|---|---|---|
| MTP | Transfer of any files | Slow speed, errors on large files | All models. |
| PTP | Photos and videos (like a camera) | Can't see any other folders. | All models. |
| RNDIS | Internet through USB (USB-tetering) | Not for files. | Redmi with MIUI 12+ |
| ADB | Advanced transmission via command line | Requires skills | All models with unlocked loader |
To switch between modes:
- Connect Xiaomi to the PC.
- Swipe down the notification panel.
- Tap on the notification "USB-connectionβ (if not, see section 1).
- Choose the right mode.
For PTP (photo): This mode is useful if MTP doesn't work, but you only need to reset photos.The computer will see Redmi as a digital camera - the files will be in the DCIM folder.

4. Solving typical connection errors
Even with the right settings, Xiaomi Redmi may not connect to a PC. Consider the most common errors and their solutions:
β οΈ Note: if the phone starts charging when you connect, but is not defined as a drive, check the cable. Cheap cables often have only 2 wires (power), without wires for data transmission.
- π« "Device not identified": Remove all Xiaomi drivers in Device Manager β Controllers USB. Turn off the phone, reboot the PC, reconnect.
- π "Media device MTP No response: Turn on the phone Flight mode, connect USB, Then turn off flight mode. Sometimes it helps to reset the Warehouse and USB customized.
- π΅ Phone connects but folders are empty: It's a bug MIUI. Go to Settings. β Warehouse β Settings (cogs) β Show system files.
- π Charging only, no data transfer: Check if Charging or Optimization is enabled in the settings USB (firmware).
If nothing works, try connecting to another computer (like MacOS or Linux), and if Redmi is there, the problem is with your PC drivers.
π‘
On Redmi Note 11 and later, you may need to confirm access on your phone when you first connect to your PC. If the notification doesnβt appear, unlock the screen and check the notification panel.
5. File transfer without USB: alternative methods
If USB-The connection is not working or the cable is not available, use one of these methods:
- π Mi Drop (built-in app): Open Mi Drop on your phone, select files β Send. β On a PC, open your browser and go to the address provided (e.g. 192.168.1.100:8080).
- βοΈ Cloud services: Upload files to Google Drive, Mi Cloud or Yandex.Disk, then download to PC (>10GB will do for Mega.
- π‘ FTP-server (for advanced): Install the application FX File Explorer or Solid Explorer, Enable FTP-server and connect via FileZilla or Windows Explorer at ftp://IP_phone address:2221.
- πΆ Local area network (SMB): On your phone, turn on Wi-Fi Transfer to Mi Drop or use the LocalSend app (similar to AirDrop).
Wi-Fi transmission speeds are usually lower than USB 3.0, but for documents or photos, that's enough. For 4K video, you'd better use a cable.
π‘
Mi Drop is the easiest solution for transferring files without USB, but only works on one local area network. For larger files (>1 GB), it is better to use cloud or FTP.
6. Optimization of data transfer speed
If files are copied too slowly (for example, a 10GB movie is transmitted for more than an hour), check these options:
- π Use it. USB 3.0: Ports USB 3.0 (blue) is 10 times faster than the USB On the Redmi Note 10 Pro and newer, this is especially noticeable.
- π¦ Archive files: If you transfer a lot of small files (such as photos), pack them into your files. ZIP/RAR. This will reduce the transmission time to 30-50%.
- π« Disable the antivirus: Programs like Kaspersky or Avast scan every file you transfer, slowing down the process.
- π Format the flash drive in exFAT: If you copy to an external drive, format it in exFAT (not exFAT). FAT32) β This will speed up the work with large files.
To check the connection speed, use the CrystalDiskMark utility (serial recording test). Normal indicators for USB 3.0 - 80-120 MB / s. If the speed is below 20 MB / s, the cable or port is a problem.
7 Security: How to protect data during transmission
File transfers over USB or Wi-Fi can be vulnerable to interception, especially on public networks.
- π Encrypt sensitive files: Archive important documents with a password before transfer (for example, through a password). 7-Zip coded AES-256).
- π΅ Turn off Debugging by USB" after use: Mode ADB Opens access to the system. After transferring files, disable it in Developer Settings.
- π¨ Donβt connect to public PCs: In Internet cafes or libraries, computers can be infected with viruses that steal data from connected devices.
- π‘οΈ Use it. VPN Wi-Fi transfer: If you transfer files via Mi Drop or FTP On the public network, turn on VPN (For example, ProtonVPN).
β οΈ Attention: Xiaomi Redmi with unlocked bootloader when connected to PC via USB You can accidentally erase the data by fastboot erase userdata. Always check the commands you type into the user. ADB!
