Owners of Xiaomi, Redmi and Poco smartphones often face situations where important documents or personal photos disappear from public access. This does not always mean deleting files; users often hide them themselves or hide system partitions for the sake of order. In the Android operating system, which is the basis of the MIUI shell and the new HyperOS, there is a mechanism for hiding files that is available without third-party applications.
Understanding how to manage directory visibility is essential to keeping data private and keeping it clean. The standard file manager from a Chinese manufacturer has powerful functionality that is often underrated. In this article, we will go into detail on how to detect and manage hidden objects.
You will learn not only to find lost data, but also to properly configure the display of system files, which is critical for deep memory cleaning or data transfer. We will look at both standard tools and specific features of working with memory in modern versions of firmware.
Disclosure of files in MIUI and HyperOS
Xiaomi's security system provides multiple layers of information protection, and the usual concealment of a folder does not remove it, but only changes the visibility attributes for a standard Explorer, and the file manager ignores such directories in a normal scan, unless the appropriate viewing mode is activated.
And then there's the Hidden Album or Hidden Folder feature, which requires separate authorization, which is not just changing the visibility attribute, but moving data to an encrypted memory area, and accessing it through a special gesture or password.
It is important to distinguish between system hidden folders that start from a dot and user folders that are hidden through privacy settings. The former often contain application configuration data, and the latter contain your personal information. Incorrect interference with system files can lead to instability of the smartphone.
⚠️ Warning: Mindlessly removing hidden system folders (such as those that start with a dot) can result in resetting app settings or losing progress in games.
To work with a file system, you only need access to the root directory or superuser rights in rare cases. In 95% of situations, standard tools provided by the manufacturer are enough, and the main thing is to know where to look for visibility switches.
Why do the files hide themselves?
Use of a Standard Conductor
The easiest way to see all the contents of memory is to use the built-in Explorer app. Unlike many other shells, the MIUI allows you to flexibly configure the display of data. First, open the application and go to the top menu.
In the display settings that open, you need to find the item "Show hidden files." Once this slider is activated, the system will rescan the drive and display all the directories that have the hidden attribute, this applies to both system and user folders.
Visually, these files often feature translucent icons that allow you to immediately understand their status. However, in some versions of the firmware, there may be no visual difference, so you should carefully monitor the names. Hidden folders names in Android Linux-based often begin with a dot symbol.
☑️ Checking the conductor's settings
If the files don't appear after you turn on the option, they may have moved to a secure area, in which case the standard viewer won't see them without additional authorization, check if the Guest or Second Space mode, which have their own isolated storages, is activated.
Access to the Second Space and the Hidden Album
The Second Space feature creates a completely isolated environment on your device, and files created or uploaded there are not visible in the main space, even if you enable the display of hidden files, a level of security higher than simply hiding attributes.
A special password is used to move between spaces, PIN-If you forget you created a second space, check the settings in the Settings menu. → Additional settings → Second space.
The same thing happens with the Hidden Album in the Gallery, where the photos and videos that are added are physically moved into a secure container to be seen:
- 📁 Open the Gallery app and go to the Albums tab».
- 👇 Pull the album list down before a password or fingerprint request appears.
- 🔓 Enter your privacy password or use biometrics to access it.
Files from the hidden album can be returned to the general gallery, but this also requires authorization. Remember, resetting the phone to the factory settings without first leaving the second space will lead to irretrievable data loss in it.
Configuring the display of system files
For advanced users who are engaged in cleaning cache or searching for residual files of remote applications, you need to see absolutely all directories. In Android, there is a division into user data and system files, the latter are often hidden by default to avoid accidental damage.
To enable their display, sometimes it is not enough to just press a button in the Explorer. In some cases, you need to use ADB (Android Debug Bridge) or get Root rights, although modern versions of HyperOS try not to do this. The standard way lies through the developer settings.
Activate the developer mode by repeatedly clicking on the build number in the About Phone section. Once the Developer Menu appears, look for items related to logging or debugging the file system, although direct access to root files through the standard UI is often closed by Google's security policies.
| Type of folder | Location. | Can be removed | Risk of removal |
|---|---|---|---|
| .thumbnails | DCIM /.thumbnails | Yes (to be created again) | Low (slow download of thumbnails) |
| .android | Root of memory | No. | High (system failure) |
| MIUI/.gallery | MIUI /.gallery | No. | Medium (galleries failure) |
| .temp | Different annexes | Yes. | Low (loss of temporary data) |
When you analyze your busy space, look at the size of your folders. If you see a multi-gigabyte directory called.cache or.data, it could be a streaming service or messenger cache, and cleaning those folders through your application settings is safer than manually deleting files.
💡
Use the Cleanup feature in the Security app to delete temporary files. This is safer than manually deleting folders that start from a dot, since the system knows which files can be deleted without harming the application.
Finding hidden folders through your computer
Connecting your smartphone to a PC via USB-cable is one of the most reliable ways to see the real structure of files. Windows or macOS has its own settings for displaying hidden objects that can overlap the settings of the phone.
Once connected, select the USB File Transfer (MTP) mode. In Windows Explorer, you must go to the View tab and tick Hidden Items, only after that you will see folders hidden at the Android file system level.
However, files from Hidden Album or Second Space cannot be seen through a computer without entering a password directly on the phone, which is encrypted and only accessible to the smartphone operating system after successful user authentication.
To work with a file system through a PC, it is often more convenient to use the command line or specialized programs like Total Commander with the ADB plugin. This gives more flexible control over access rights and allows you to copy system logs to diagnose errors.
⚠️ Note: When connecting to your computer, do not agree to debugging requests USB, If you don't trust that PC, it could give a third-party device full access to your files.
Third-party file managers
If the standard Xiaomi tool seems inconvenient or not functional enough, you can always install an alternative. Popular file managers such as Solid Explorer, FX File Explorer or Files by Google often have a more intuitive interface for working with hidden data.
Many of these applications allow you to quickly switch between Hidden and Vidimo modes with a single swipe, and they can highlight folders that take up a lot of space or duplicate files, making it easier to maintain memory.
When installing third-party software, be sure to give it the necessary permissions to access all files. In newer versions of Android (11 and above), the system requires explicit confirmation of access to storage for each application separately.
Some managers allow you to create pseudo-hidden folders by changing their attributes in one click, which is convenient for quickly organizing the workspace without deep encryption, but for truly sensitive data, it is better to use built-in MIUI protections.
💡
Third-party file managers give more freedom in sorting, but Xiaomi’s built-in protector stores passwords and biometric data to access files more reliably.
