Xiaomi's internal smartphone drive isn't just a place to store photos and apps, it's hidden system files, cache, account data, and even MIUI backups. But some folders are limited by default, because the manufacturer blocks critical partitions from changing to prevent crashes, and the problem is that even experienced users sometimes can't find the files they want or get the rights to edit them.
This article will help you understand how to get full access to Xiaomi internal memory, from basic methods through standard Explorer to advanced solutions using ADB and computer. We will look at all the current ways for devices on MIUI 12-14 and HyperOS, including bypassing restrictions on models with a locked bootloader.
If you just need to copy photos or music, you just need to connect your phone to your PC, but you need to take additional steps to work with system folders (/data, /system) or hidden files. Below you will find step-by-step instructions for different scenarios, as well as warnings about possible risks.
1. Access via standard MIUI conductor
The easiest way to view files on Xiaomi is to use the built-in File Manager app, which is pre-installed on all devices with MIUI and HyperOS, but has limitations: some system folders are hidden and editing protected files is blocked.
To open the conductor:
- Click on the Files icon on the home screen or in the app menu.
- Select the Device tab (or βInternal Memoryβ).
- Scroll down the list β all available folders will be displayed here: DCIM (photo), Downloads (downloads), Music, etc.
What can be done without additional rights:
- π View and copy media files, documents, APK.
- π Use a search by file name (the button of the magnifier at the top).
- ποΈ Delete unnecessary files (except system files).
- π Move data between folders or to a SD- card.
Limitations of the standard conductor:
β οΈ Warning: Folders /data/data (application data), /system (system files) and /vendor are not displayed here. Trying to access them through third-party file managers (e.g. Solid Explorer) will result in a "No permission" or "Folder is empty" error.
If you need to edit files in these sections, go to the following methods.
2. Connect to the PC in file transfer mode (MTP)
The way for those who prefer to manage files via a computer is suitable for all Xiaomi models, including Redmi, POCO and Black Shark, but does not allow access to system partitions.
Step-by-step:
- Connect your smartphone to your PC via the original USB- cable (cheap cables may not support data transfer).
- The phone will have a notification, "Charge over USB," and tap it.
- Select βFile Transferβ (or MTP β Media Transfer Protocol).
- On the computer, a conductor window with internal memory folders will open.
What you can see in MTP mode:
| folder | Contents | Access. |
|---|---|---|
| DCIM | Photo and video from the camera | Reading/writing |
| Downloads | Uploaded files from the browser | Reading/writing |
| Music | Audio files | Reading/writing |
| Android | Obb (game data) and data (limited) folders | Partial |
| MIUI | Backups, themes, wallpaper | Only reading. |
Challenges and solutions:
- π Computer can't see phone: Try another cable or port USB. On the phone, check that MTP mode is selected, not Charge only.
- π No folder access: System directories (/data, /system) are hidden even in MTP mode. You need root or ADB to view them.
- π’ Slow gear: Use USB 3.0 (port blue) and high speed cable.
π‘
If Windows doesnβt recognize the device, install Mi PC Suite drivers from Xiaomiβs official website. Linux may require manual adjustment of the udev rules.
3.Use ADB to Access Hidden Folders
Android Debug Bridge (ADB) is a debugging tool that allows you to manage files on your smartphone via the computerβs command line, an advantage of which is that you can view and copy files from system folders without root rights, but editing is still limited.
What you need:
- π₯οΈ Computer with Windows, macOS or Linux.
- π± Included debugging by USB phone-on.
- π§ Installed ADB- Drivers.
Instructions:
- Activate Developer Mode: Go to Settings β About Phone. Tap 7 times on MIUI Version. You will see a notification that says, "You've become a developer." Go back to the main settings menu, find a new section called "Developers" and turn on "Debugging on USB" and confirm permission.
"File transfer"
adb devicesWait for the serial number of the device to appear.
adb shell ls /sdcard/To copy the file to the PC:
adb pull /sdcard/Download/file.txt C:\Users\YourName\Desktop\ADB commands for working with files:
| Team team. | Description |
|---|---|
| adb shell ls / folder/ | Viewing the contents of the folder |
| adb pull /path/to/file C:\folder\on\pc | Download a file from your phone to your PC |
| adb push C:\file\on\pc/path/on/phone | Download a file from the PC to the phone |
| adb shell cp /source/path /target/path | Copying a file inside your phone |
Important: Adb shell rm or adb shell mv commands to delete/move files in system folders (/data, /system) require root rights. Without them, you will get a Permission denied error.

4. Obtaining root rights for full access
Whether you need to edit system files, delete pre-installed applications or change MIUI settings at a deep level, you canβt do without superuser rights (root) Warning: this will void the warranty and can lead to a device blink (breakdown) if you do not care.
How to get root on Xiaomi:
Squeeze Magisk for root:
- Download Magisk from GitHub.
- In TWRP, select βInstallβ and specify the path to the Magisk.zip file.
- After download, check root permissions through the Magisk Manager app.
What root does:
- π Full access to /data, /system, /vendor.
- ποΈ Ability to remove system applications (bloatware).
- βοΈ Edit build.prop files, hosts, and other configurations.
- π± Install custom firmware (LineageOS, Pixel Experience).
β οΈ Warning: On HyperOS devices (e.g. Xiaomi 14, Redmi Note 13), root is complicated by new security mechanisms. Use current Magisk versions (26.0+) and proven guides for your model.
What happens if you remove the system application?
5. Alternative methods: FTP- server and Wireless ADB
If you don't have a cable on hand, or if you want to manage files over Wi-Fi, use one of these methods, which is convenient for fast data transfer without a physical connection.
1. FTP- server via the application (without root):
- π± Install FX File Explorer or Solid Explorer from Google Play.
- π In the application settings, find the FTP- server and turn it on.
- π₯οΈ On a PC, open the explorer and enter the address of the ftp://192.168.x.x:port (the data will be displayed in the application).
- π A login/password may be required to access (as set out in FTP settings).
2. Wireless ADB (over Wi-Fi):
- Connect your phone to your PC via USB and do: Adb tcpip 5555
- Turn off the cable and connect via Wi-Fi: adb connect 192.168.x.x:5555 (replace IP with the current phone address).
- You can now use all adb commands without wire.
Limitations of wireless methods:
- πΆ The transmission speed is lower than that of USB 3.0.
- π Without root, you won't have access to system folders.
- π Increased battery consumption.
π‘
For temporary access to files (for example, copy the error log) enough FTP or Wireless ADB. For constant work with system data need root or ADB via USB.
6. Solving common errors
When working with internal memory Xiaomi users often face typical problems.
1. "Folder is empty" or "No access":
- π Reason: No permission to view system folders.
- π§ Solution: Use ADB to copy files (see 3. Get root (section 4). For the /data/data folder, try the command: adb shell run-as com.example.app cat /data/data/com.example.app/file.txt > file.txt (replace com.example.app with the desired application package).
2.The computer does not see the phone in MTP mode:
- π Cause: Faulty cable, outdated drivers, or failure in settings USB.
- π§ Solution: Try another cable (original from Xiaomi). On your phone, go to Settings β Additional β For Developers and select βRevoke Permissions USBβ, then connect again. On PC, update drivers through Device Manager (section βControllers USBβ).
3. The error "Permission denied" in ADB:
- π Reason: Not enough licenses for surgery.
- π§ Solution: To read system files, use: adb shell su -c "cat /system/build.prop" (root required). If you want access to application files, use run-as (see above).
4.After receiving root, files were lost:
- ποΈ Cause: Incorrect partition mounting in TWRP or failure in Magisk firmware.
- π§ Solution: Reboot to TWRP and check if partitions (Mount β System, Data) are being mounted. If files are missing after firmware, restore them from the backup TWRP.
7 Security: How to avoid losing data
Working with internal memory is always fraught with risks.
- π₯ Delete critical files β brick (phone not turned on).
- π Incorrect editing build.prop β cyclic reboot.
- π Data loss when settings are reset or firmware is lost.
How to minimize the risks:
- Backup: Through TWRP: select Backup and select Data, System, Boot. Through MIUI: Settings β About Phone β Backup (does not save system files!).
Check the commands:
adb shell rm -rf /
Use reliable sources:
TWRP
Magisk
Test the changes:
β οΈ Warning: On HyperOS devices (2023-2026), locking a bootloader can lead to hard-brick (irrecoverable breakage) if you use outdated versions of the unlock tools. Always check that the Mi Unlock Tool is compatible with your model.
Checklist before critical operations:
Backup in TWRP| Check battery power (minimum 50%) | Download current versions of tools (ADB, Magisk) | Disable antivirus on PC (can block ADB) | Keep the original firmware on hand to restore-->
