Users of Xiaomi, Redmi and Poco smartphones often face the need to hide personal photos or important documents from prying eyes. The standard MIUI shell and its current version of HyperOS offer built-in mechanisms for this, but they are not always obvious at first glance. Hidden folders can be invisible in the gallery, but still occupy space in memory or be accessible through a file manager.
In this article, we will explore all the ways to find and manage hidden files on your device, where data is physically stored, how to get into a secret album, and what to do if folders are lost after a system update. Understanding the structure of the Android file system will help you better control your digital security.
The mechanism of operation of hidden files in MIUI and HyperOS
Xiaomi’s system uses a special encryption and renaming algorithm to hide content, so when you send a file to a hidden album, it doesn’t just hide, it moves to a secure memory area with a changed name. This is done in order to even connect the smartphone to the computer through USB-cable in file transfer mode, this data remained inaccessible without a password.
The technical implementation of the concealment process involves changing the file attributes and moving it to a system directory that is not displayed by standard viewers, PIN-This provides a high level of security, but makes it difficult for the owner to find files if necessary.
💡
Hidden files are encrypted separately from the main system, so recovering them after resetting settings without a backup in Mi Cloud is impossible.
It is important to understand the difference between simply hidden files (via visibility settings) and files in Hidden Album. The former can be seen in Explorer if you enable system files to be displayed, while the latter are securely encrypted. Files from the hidden album are physically moved to the partition. MIUI_Gallery_Cloud, This makes them invisible to most third-party applications.
How to find a hidden album through the Gallery
The easiest way to access hidden photos and videos is to use the standard Gallery app, which works on all current firmware versions, including MIUI 12, 13, 14 and HyperOS. The interface may vary slightly, but the logic of action remains the same for all models.
To enter the hidden section, you need to make a specific gesture that is not conspicuous. Open the Gallery app and go to the Albums tab. Then pull the list of albums down until there is a vibration or visual effect, then release your finger. The system will request a password or biometric authentication.
Once you have successfully logged in, the hidden album interface will open, where you can view content, add new files or delete them. Note that the files added here disappear from the main "Recent" and "Photos" feeds, which ensures privacy.
- 📷 Open the Gallery app on the home screen.
- 👆 Go to the Albums tab at the bottom of the screen.
- ⬇️ Pull your finger down the center of the screen and hold for a split second.
- 🔒 Enter your privacy protection password or use your fingerprint.
If the gesture doesn’t work, make sure the hidden album feature is activated in the settings. Sometimes after major Android updates, privacy settings may be reset, requiring re-activation.
Finding hidden folders through the file manager
For more advanced users who need to work not only with media files, but also with documents, archives or other media. APK-In Xiaomi, it's called "Files" or "Files," and this tool allows you to see the structure of directories, including those that are usually hidden from the user's eyes.
To see all folders, including system and hidden, you need to activate the appropriate display mode. Standard folders that start from a dot (for example,.thumbnails) are hidden by default in Android. However, folders created by the user to hide data often have special attributes.
⚠️ Warning: When working with the file system, be extremely careful. Deleting system files or changing their structure can lead to unstable smartphone operation or data loss.
To enable the hidden elements display, open Explorer, click on the menu (three bars or dots) and select Settings. Find Show Hidden Files and activate it. Then folders with translucent icons will appear in the memory root and internal directories.
☑️ Checking the conductor settings
The hidden gallery album in the conductor looks like an encrypted file or folder with the name MIUI_Gallery_Cloud Or something like that, which is only accessible through login, and you can't just copy files from there without first "disclosing" them in the Gallery.
Setting up visibility and confidentiality parameters
Xiaomi's ecosystem offers flexible privacy management tools, so you can not only hide albums, but also hide entire apps, messages, or settings, all of which are combined under the Privacy Protection section.
To access the advanced settings, go to Settings → Privacy Protection → Hidden Album. Here you can change the password, configure the hidden album icon in the gallery (so it doesn’t cornen your eyes or is on hand), and manage cloud sync.
Syncing hidden files with Mi Cloud is a separate topic, and if it is enabled, your hidden photos will be shared on other devices that log in to the same Mi Account, which is convenient but requires attention to account security.
| Parameter | Description | Recommendation |
|---|---|---|
| Security password | A separate PIN or pattern lock | Use a different screen unlock code |
| Fingerprint. | Enable for quick access | |
| Synchronization | Upload to the cloud | Only if there is a backup importance |
| Visibility | Gallery display | Hide the icon for maximum secrecy |
Remember that changing your privacy password does not change the password for encrypting files already hidden. Old files will only remain accessible with the old password until you move them again.
What to do if you forget the password from the hidden album?
Using the Second Space mode for isolation
If a standard hidden album isn’t enough, Xiaomi offers a “Second Space” feature, which is a fully isolated environment inside your smartphone, with its own desktop, its own apps, and its own file system.
Switching between the main and second spaces is done by fingerprint or password. To an outsider, your phone will look like normal, even if it is unlocked (in the main space), a level of security comparable to having two different phones.
In Second Space, you can install separate versions of social networks, banking apps, and store files there, and the data in those spaces doesn't overlap unless you set up file transfers yourself, which is the perfect way to separate work and personal life, or hide very sensitive information.
- 🛡️ Go to Settings. → Second space.
- 🚀 Click on “Enable Second Space” and follow the instructions.
- 👆 Set up a separate unlock method (e.g., another finger).
- 📂 Transfer files through the built-in File Transfer tool».
⚠️ Attention: Deleting the second space will permanently delete all the data stored inside it.
Problems with folder visibility after Android update
Frequently, after updating the firmware from MIUI 13 to 14 or switching to HyperOS, users find that hidden folders have disappeared or stopped showing correctly, due to changes in Google’s security policy and the reworking of file managers.
Newer versions of Android (11, 12, 13, 14) severely restrict applications from accessing the file system (Scoped Storage), old methods of hiding through file renaming may stop working or files may become visible in third-party explorers if you do not update your privacy settings.
💡
After a major system update, always check the Privacy Protection settings and re-activate the hidden album so that the files are re-indexed correctly.
If you're updated and can't find files, try logging into the hidden album through a gallery gesture. Often the files stay in place, but the shortcut or access to them is "lost" in the interface. Also check if the sync has turned off, which could restore the album metadata.
In some cases, cleaning the cache of the Gallery and Security app helps. Go to Settings → Apps → All apps, find what you want and select Clear Cache. Don't confuse it with Clear Data, otherwise the settings may reset.
