Xiaomi’s current smartphones, powered by the MIUI shell or the new HyperOS, have become more than just communication devices, but digital repositories of our personal lives: documents, work projects, and personal photos and videos that are better restricted from prying eyes. The standard location of files makes them vulnerable if a phone is in the hands of a curious friend or lost.
Fortunately, Xiaomi engineers have built powerful privacy protection tools that don’t require third-party software to be installed, and you can hide a folder on Xiaomi’s Android in a number of ways: using the Hidden Album feature in the gallery, or creating secure folders through the system Explorer, which provide different levels of access and are suitable for different use cases.
In this article, we will take a look at all the available methods of hiding data, from simple gallery settings to creating an isolated Second Space space, how to set up biometric protection and what to do if you forget the password from hidden files.
Why hide files and folders on Xiaomi
The need to hide certain data often arises not only from paranoia but also from practical security. Privacy in the digital age is becoming a luxury that is easy to provide with the right settings. Hiding folders prevents colleagues, children or screens from accidentally viewing personal photos.
It's also an efficient way to structure space, and some users prefer to remove rarely used but important system or work directories from the public domain so as not to clutter up the interface, and MIUI allows you to do this natively, without the risk of damaging the system, as is the case with questionable applications from the store.
⚠️ Warning: Hiding a folder is not the same as military-standard encryption. If the device is hacked by professional data recovery methods, hidden files can theoretically be found, although they will not be available to the average user.
Xiaomi’s built-in tools are preferable to third-party lockers, as system tools have deeper access to the file system and are better optimized to work with the device’s memory.
Hiding photos and videos through the Gallery
The most popular user request is “how to hide a folder,” but most often it is about media files. The built-in Gallery app on Xiaomi smartphones has a special feature called “Hidden Album,” which is ideal for photos and videos, since it completely removes them from the shared tape and even from the file system for standard viewing.
To activate this feature, you need to open the Gallery app and go to the Albums tab. Scroll down the album list to the bottom. There you will find the Hidden Album item. The first time you click, the system will prompt you to enable this feature and set a password or use biometrics.
Once activated, the algorithm becomes intuitive, so you can move files there in a number of ways, making it easy to do in any situation.
- 📸 Select a photo in the tape, click “More” and select “Add to a Hidden Album».
- 📁 Open the hidden album itself, click the add button and select files from memory.
- 🖐 Use the swipe-down gesture in album viewing mode (if enabled in the settings).
It is important to understand that files in a hidden album take up space on the phone, but they cannot be seen through a standard conductor or when connecting the phone to a computer via USB in file transfer mode until a password is entered. MIUI encrypts the display of this data.
Creating Hidden Folders Through a Explorer
If your goal is to hide not only the media, but also documents, archives or other media. APK-File Manager, which allows you to create hidden folders that you can't see in normal file system mode.
To get started, open the Explorer app, and at the top of the screen you'll see tabs, one of which is called Folders, and that's where you access directory management, and unlike a gallery, it creates a separate, secure space.
Open Explorer -> Tab "Folders" -> Press "Hidden folders" -> Enable the functionOnce the function is enabled, you will be prompted to set a password. The password from the hidden folder in Explorer may differ from the screen unlock password, which increases security, and it is recommended to use a complex digital code or pattern lock.
When the function is activated, you can move any files to that storage. Just select the file in normal mode, click "More" and select "Hide." The file will disappear from the current location and only appear inside the secure directory.

Second Space setup for complete isolation
For users who want the highest level of privacy, Xiaomi offers Second Space, which is not just a hidden folder, but a full-fledged second operating system inside your smartphone, and has its own apps, settings, and files completely isolated from the main space.
Switching between spaces is instantaneous and can be configured through a special label on the desktop or, more conveniently, through a fingerprint, where you assign one finger to enter the main space and the other to enter the second, hidden space.
This method is ideal for separating Work and Personal, or if you give a phone to a child to play with but don't want it to get to your bank apps or personal photos.
- 🔒 Complete isolation: applications do not see files from the main space.
- 👤 Different accounts: You can log in to different Google or Mi accounts.
- ⚡ Quick switching: via fingerprint or password.
To activate Second Space, go to Settings, find the Additional (or Advanced Settings) section, and select Second Space. Follow the configuration wizard's instructions.

Use of the “Protection” application and encryption
MIUI has another powerful tool, Security, which combines antivirus, cleanup and privacy, and it's where you can find additional settings to hide data if standard methods don't show up for some reason.
The Protection section often duplicates the entrance to hidden albums and folders, but you can also set up Application Protection here. While this doesn't hide the folder completely, it puts a password on the Explorer or Gallery login itself, which is an effective barrier.
In addition, you can activate Guest Mode or Child Mode in the security settings, which temporarily restricts access to certain features and folders, making them invisible to the current user.
| Method | Type of data | Level of protection | Difficulty setting up |
|---|---|---|---|
| Hidden album | Photos, Videos | Medium. | Low. |
| Conductor | All files. | High-pitched | Low. |
| Second Space | Complete system | Maximum | Medium |
| Application lockdown | Access to the software | Basic | Low. |
Combining these methods yields the best results, for example, you can put documents in a hidden Explorer folder and then put a password on the Explorer application itself.
💡
Change passwords from hidden storages regularly, especially if you have given the screen unlock code to trusted people.The old password can remain in the person's memory and become a vulnerability.
Restoration of access and frequent problems
Security is a balance between convenience and security. Often users are faced with the problem of “how to hide a folder”, forget about it and subsequently can not find their files or remember the password. Android on Xiaomi there is no “magical” button to reset passwords from hidden folders without losing data, as this is contrary to the concept of security.
When you set a password to a hidden album or folder, the system urges you to link Mi Account, which is a critical step. If you forget the password, it's through the account that you can try to restore access. Without linking to a cloud account, the chances of returning data tend to zero.
⚠️ Warning: Resetting your phone to factory settings won’t delete files from the hidden album if they’re physically on internal memory, but can make them unavailable to the system if you don’t backup encryption keys.
If you change your phone and move data, the hidden folders may not automatically show up, but you need to re-activate the concealment function in the new device and log into the same Mi Account so that the system can "see" the protected containers.
A common mistake is to try to find hidden files through a computer. When connected via USB, Xiaomi's hidden folders don't appear in Windows/macOS Explorer, which often scares users who think the files are missing. They're not gone, they're just hidden by the shell software layer.
💡
The main key to recovery is Mi Account. Never ignore the system's offer to link your account to the file hiding feature, otherwise you risk losing access to the data forever.
