Owners of Xiaomi, Redmi, and POCO devices often face the challenge of finding certain data that is not displayed in a standard gallery or explorer. Hidden files can take up gigabytes of memory, contain important system logs, or sensitive application data. Understanding the structure of the MIUI and HyperOS file system is critical for deep cleaning or backup.
By default, Android hides files that start from a dot, as well as system directories, so that the user does not accidentally delete critical components. However, when you connect to a computer or use advanced file managers, this “invisibility” disappears. You need to know the exact ways so that you do not get confused in hundreds of folders.
In this article, we will not only look at the standard paths, but also the nuances of accessing protected partitions, we will look at how to enable the display of hidden objects and the risks of tampering with system files, this guide will help you effectively manage your smartphone memory.
Basic structure of Android file system on Xiaomi
Xiaomi’s smartphone file system is based on the Linux architecture, which implies a clear hierarchy. The root directory is denoted by the symbol /, and all branches diverge from it. User data is usually stored in the /sdcard/ or /storage/emulated/0/ section, which is physically located in the device’s internal memory.
It is important to understand the difference between system partition and user storage: System files are protected by access rights and are not visible without special permissions. User files are available immediately, but some of them can be marked as hidden by application developers.
The standard MIUI Explorer hides technical debris and logs by default, requires third-party software or special debugging modes to work with them, and knowing the folder structure helps you quickly find heavy files left behind by remote applications.
- 📂 /data/ — root folder of the system, access to which is closed without Root-rights.
- 📂 /sdcard/ — emulation of an external memory card where your photos and downloads lie.
- 📂 /system/ — partition with the operating system, the change of which can lead to a brick.
⚠️ Warning: Direct file editing in system partitions can disrupt the bootloader or cause a cyclical device reboot.
How to enable the display of hidden files in the Explorer
To see files starting from a point (e.g..thumbnails), you need to change your display settings. In the standard Xiaomi Explorer app, this option is often hidden in the deep menu or not at all. FX File Explorer.
In the native interface, sometimes switching the folder view or activating the "Show Hidden Files" mode in the application settings helps, but the functionality is limited. Third-party managers give full control over the visibility of objects.
Once you turn on the option, you'll see a lot of new folders. Don't be too quick to delete everything. Many of them contain cache that speeds up applications, or game configuration files.
When working with the file system, it is important to be careful: removing the system cache can temporarily slow down the smartphone until it recreates the necessary files again.
The main paths to hidden folders and garbage
The most interesting ones for users are folders that occupy space but are not visible in the gallery, primarily.thumbnails, where you store thumbnails of your photos, which can grow to several gigabytes.
Also worth paying attention to is the Android/data/ folder. It stores the game cache and application data. In modern versions of Android, access to this folder is limited, but you can access it through a PC or special permissions.
The table below shows the main paths to hidden data that users often search for:
| The way to the folder | Description of the contents | Can I remove it? |
|---|---|---|
| DCIM/.thumbnails | Photo and video miniatures | Yes (recreated) |
| Android/data/ | Cash of games and apps | Careful (logins will fly) |
| MIUI/debug_log/ | Logs of system debugging | Yes. |
| .android/ | Android system data | No. |
Cleaning the.thumbnails folder is a safe way to free up space, but the system will create it again once you open the gallery, and more complex manipulations are required to clean it permanently.
💡
To keep the.thumbnails folder from growing, some users create a file with the same name instead of a folder, but without extension.This blocks the creation of thumbnails, but the gallery can run slower.
Access to system files through Root rights
To access truly hidden files located in /data/, superuser or Root rights are required. Obtaining these rights removes security restrictions, but deprives of warranties and can disrupt banking applications.
The process of getting Root usually involves unlocking the bootloader and installing Magisk.This is a complex procedure that requires you to follow the instructions for your specific Xiaomi model.
Once you have the rights, you can see and edit files at the root of the system, which allows you to remove embedded software that cannot be removed by standard methods.
⚠️ Warning: Making changes to system files with Root rights without a backup can cause a smartphone to fail completely.Always back up!
Using Root-enabled file managers, such as Root Explorer or MiXplorer, allows you to navigate safely through system directories.The interface warns you of the dangers before editing critical files.

Hidden files of WhatsApp, Telegram and messengers
Messengers create their own hidden directories to store temporary files and sent media. WhatsApp is a WhatsApp/Media/.Statuses folder that stores the statuses of contacts you have viewed.
Telegram stores the cache in the folder Android/data/org.telegram.messenger/files. There can be gigabytes of videos and photos that have been formally deleted from the chat, but remained in the memory of the phone.
Cleaning these folders regularly helps to free up space, but deleting files from active messenger folders can result in loss of correspondence history or media within the application.
- 📸 WhatsApp Status – a hidden folder with statuses that can be saved.
- 📄 Telegram Cache – temporary files that can be cleaned through the settings of the application.
- 🎵 Voice Messages – Voice recordings and voice messages are often hidden in Audio subfolders.
To clean up the Telegram cache, it is safer to use the built-in Data and Memory Use feature than to climb into the file system manually, ensuring that important files are not accidentally deleted.

Access issues in Android 11, 12, 13 and later
Starting with Android 11, Google has imposed strict restrictions on access to the Android/data and Android/obb folder. Standard conductors no longer see their contents. This is done for security, but makes life difficult for advanced users.
To get around this limitation on Xiaomi, you can use special methods, such as activating hidden mode Explorer through ADB or using file managers who are able to request special permissions (for example, Material Files).
The ADB command to temporarily remove restrictions is complex, but it is effective, and it allows you to access data from other applications for a specific session.
adb shell appops set com.android.permissioncontroller ALLOW_ACCESS_RESTRICTED_SETTINGS allowOnce the command is executed and the Explorer restarted, access to the secure folders can be restored, but with each security update, Google closes these loopholes, requiring new solutions.
⚠️ Attention: Use ADB commands require a driver installed and minimal command line knowledge. A syntax error may fail or cause a system error.
Owners of HyperOS devices should be especially careful, as the new shell strengthens file system protection, and some methods that worked on MIUI 14 may not work.
💡
Android/data access restrictions are a security measure that Google cannot completely circumvent without Root rights or complex ADB manipulations.
