Where hidden files are stored in Xiaomi Explorer: system folders and secret MIUI directories

Why hidden files in Xiaomi are not visible by default

Xiaomi’s MIUI-based smartphones hide some system files and folders from the user, a standard practice for Android devices, for three key reasons: security (so that the user does not accidentally delete critical data), simplification of the interface (hiding technical details from beginners), and compliance with Google’s policies (some system files are not designed for manual editing).

However, there are times when access to hidden files is necessary: recovering deleted data, manually configuring configurations, cleaning the app cache or installing custom firmware. Unlike β€œpure” Android, where it is enough to enable the display of hidden files in the settings, in MIUI this process can be complicated by additional layers of protection, for example, system folders like /data or /system require root rights, and some directories (for example,.thumbnails or.nomedia) simply do not display without special actions.

It is important to understand the difference between hidden user files (e.g., application configs with a dot at the beginning of the name) and system hidden data (Android folders, update cache). The former can be made visible through Explorer settings, while the latter often require additional tools or even unlocking the bootloader.

How to enable the display of hidden files in the standard MIUI Explorer

The easiest way to see hidden files is to use Xiaomi’s built-in Explorer (aka File Manager or Explorer).The algorithm of actions depends on the version of MIUI, but the general scheme looks like this:

  1. Open the Explorer app (the folder icon on the desktop or in the application menu).
  2. Slip along three horizontal lines (☰) in the upper left corner to open the side menu.
  3. Select Settings (or Settings in global firmware).
  4. Scroll down to Advanced and activate the Show Hidden Files switch.
  5. Return to the root directory (/) and update the file list with the swipe down.

After that, folders and files will appear in Explorer, whose names begin with a dot (for example,.config,.cache or.config.android_secure). However, this method will not show system directories like /data or /system β€” They need root access or ADB-team.

If your Explorer does not have a β€œShow Hidden Files” option, update the application via Google Play or install an alternative file manager, such as Solid Explorer or FX File Explorer.

Where to look for hidden files: Key system folders Xiaomi

Hidden files in Xiaomi are distributed in several major directories, and their location depends on the type of data:

  • πŸ“ Personal hidden files of the user: stored in /storage/emulated/0/ (internal memory or SD-map (/storage/XXXX-XXXX/). You can find folders like.thumbnails (image miniatures),.nomedia (files excluded from the media scanner),.cache (app cache) here).
  • πŸ”§ Application configuration files: usually in the /data/data/[Application name packet app]/ For example, WhatsApp settings are stored in /data/data/com.whatsapp/. Access only to root!
  • πŸ”„ Cash updates. MIUI: folder /cache/ It contains temporary update files and system logs, and cleaning up this folder can help with crashes. OTA-updates.
  • πŸ“± System settings: catalog /system/ It includes firmware, kernel and pre-installed applications. Changes without root can be a knock on the device!

MIUI/storage/emulated/0/MIUITopics, wallpaper, system logYes.
data/data/Application user dataNo.
lost.dir/storage/emulated/0/lost.dirRecovered files after failuresYes.

The /data/local/tmp folder is often used to temporarily store files when installing APKs through ADB or recovering backups, and cleaning it can solve the β€œinsufficient space” issues with updates.

How to Access System Hidden Folders Without Root

If you need to view or copy files from protected directories (e.g, /data or /system), But root is not allowed, you can use it. ADB-This method works on all Xiaomi devices with debugging enabled. USB.

Instructions:

  1. Activate Developer Mode: Go to Settings β†’ About Phone and tap 7 times on the MIUI Version.
  2. Return to Settings β†’ Additional β†’ For developers and enable USB debugging.
  3. Connect your smartphone to your PC, install it ADB-Drivers and open the command line.
  4. Execute the command to copy the file (example for /data/local.prop):
adb pull /data/local.prop C:\Xiaomi_Backup\

To view the contents of the folder without copying, use:

adb shell ls /data/app/

Limitations of the method:

  • ⚠️ Reading is possible, but writing or deleting files in system folders without root is prohibited.
  • ⚠️ Some directories (e.g, /data/data/com.xiaomi.*/) They can be blocked even for reading.
  • ⚠️ Adb push commands (download files to your device) in protected folders will not work.
What if the ADB can’t see the device?
1. Check if the debugging is included USB developer-setting. 2. Install the original Xiaomi drivers from the site [en.miui.com/a-234.html](https://en.miui.com/a-234.html). 3. Try another one. USB-cable (preferably original). 4. In Windows Device Manager, update the driver for Android Device manually by specifying the folder with ADB.

Top.-5 Hidden files and folders that you should know

Not all hidden files are equally useful, but some can be useful for diagnosing or optimizing your smartphone.

  1. .thumbnails (in DCIM): Contains thumbnails of all photos and videos. Cleaning this folder won't delete the originals, but will free up space (sometimes up to a few gigabytes).
  2. Android/obb/: This is where additional game data (e.g., Genshin Impact graphics packages or Call of Duty Mobile) is stored. Deleting files will cause game crashes!
  3. MIUI/debug_log/: System log files that are useful in diagnosing errors, anr_trace contains information about "hangs" of applications.
  4. .nomedia: A file without an extension that prevents a media scanner (gallery, music player) from displaying the contents of a folder.
  5. Lost.dir: Recovered files after incorrect extraction SD-file system failures or maps often contain fragmented data.

Dangerous actions with hidden files: what not to do

Working with hidden files requires caution, and even seemingly harmless actions can lead to data loss, application failures, or system failures.

⚠️ Note: Delete or modify files in the folder /system Without root and knowledge of the structure of Android will lead to a device blink (completely inoperable). EDL-regime.

  • 🚫 Removal Android/secure: It's where the encrypted data of the applications is stored, and the loss of it is equivalent to the deletion of the programs themselves.
  • 🚫 Editing build.prop: this file in /system It contains the firmware parameters. Incorrect edits will lead to a load cycle.
  • 🚫 Cleanup /data/dalvik-cache: Dalvik virtual machine cache. its removal will cause massive app crashes after reboot.
  • 🚫 Modifying files in /efs: stored IMEI, Serial numbers and module calibration data (Wi-Fi, Bluetooth) will cause network loss!

If you accidentally delete an important hidden file, try to restore it with utilities like DiskDigger or Recuva (for internal memory you need root).

πŸ’‘

Before any manipulation of hidden files, create a full backup via adb backup or TWRP. This will save the data in case of an error.

Alternative file managers for working with hidden files

Standard MIUI Explorer is limited in functionality. For advanced work with hidden files, we recommend using third-party applications:

AnnexAdvantagesDeficienciesNeeds root?
Solid ExplorerDual-panel interface, cloud storage, FTPPaid version for advanced functionsNo (but will show more files)
FX File ExplorerBuilt-in text editor, ADB-integrationDifficult for beginnersOptionally.
Root ExplorerFull access to /data and /systemOnly for rooted devicesYes.
MiXplorerLightweight, archive support, SMBThere is no official support for Google PlayNo.

For root-access devices, Root Explorer or FX File Explorer are the best choice, allowing you to mount system partitions in read/write mode. If root is not available, Solid Explorer or MiXplorer will show more hidden files than standard Explorer, bypassing some of the limitations of MIUI.

When you first start an alternative manager, give them all the permissions you want (especially storage and debugging) and most of these apps have a Show hidden files option that you need to manually activate.

Frequently asked questions

Can I see hidden files on Xiaomi without a computer?
Yes, it is enough to enable the display of hidden files in the settings of standard Explorer or install a third-party file manager (for example, Solid Explorer). /data or /system rootless ADB will not be available.
Why are some folders still not visible after you turn on the hidden files display?
It's got to do with restrictions. MIUI And Android, folders with critical data (e.g, /data/data/) They're hidden at the core level, and you need root access or special access to view them. ADB-Also check if there are additional restrictions in the firmware (for example, in the Chinese versions). MIUI).
How to hide your files from outsiders in Xiaomi?
There are several ways: Rename the folder by adding a point to the beginning of the name (for example,.my photo). Create a.nomedia file in the folder, which hides its content from the Gallery and Music. Use the built-in Private Folder in Explorer (available on global firmware). Install third-party encryption applications, such as Andrognito or Hide Something. Importantly, renaming the folder does not protect data from power users - files will remain accessible through Explorer with hidden elements enabled.
What if after deleting hidden files, the smartphone began to slow down?
You probably deleted the cache or configuration files of the system applications. Try: Reboot the device (sometimes the system restores deleted files automatically); Clear the cache in the Settings β†’ Applications β†’ Application Management section (select "Clear Cache" for all applications); Restore files from the backup (if any); Reset the settings to factory settings (Settings β†’ Phone β†’ Resetting). If the problem persists, the file system may be damaged, in this case only the firmware will help.
How do hidden files affect Xiaomi’s performance?
Hidden files by themselves do not slow down the smartphone, but their excessive number can lead to: πŸ“‰ Slowdown: Thousands of thumbnails in.thumbnails or cache files in.cache increase storage scan time. πŸ”‹ Increased battery consumption: background processes (e.g., media scanners) waste resources on processing unnecessary data. πŸ—ƒοΈ Occupied space: folders like Android/obb It can take up gigabytes, even if you haven't played a game in a long time. 2–3 Months to clean:.thumbnails (miniatures).cache in application folders Android/obb For remote games lost.dir (if there are no important files)
