Owners of modern smartphones Xiaomi, Redmi and POCO often face the need to protect their personal data from prying eyes.Whether it is confidential documents, work photos or just personal photos that you do not want to show guests when you pick up the phone. The standard gallery and file manager MIUI offer built-in tools to solve this problem, but their functionality is not always obvious at first glance.
Android, which is based on the MIUI shell or the new HyperOS, has flexible privacy settings. However, users often look for ways to not just hide the application icon, but to put files in secure storage. This prevents accidental deleting or viewing of content without authorization. In this article, we will discuss in detail all available methods of hiding folders, from the regular system tools to the use of third-party utilities.
Keep in mind that hiding files is not the same as encrypting them, although in the context of Xiaomi mobile devices, these processes often go hand in hand. When you put data in a hidden album or folder, the system applies additional layers of protection to them, requiring you to enter a password, a pattern lock or a fingerprint to access.
Use of the Hidden Album function in the Gallery
The most popular and easiest way to hide photos and videos is to use the built-in Hidden Album feature, which is integrated directly into the standard Gallery app and does not require additional software to be installed. To activate this feature, you must first enable it in the settings, since by default it can be disabled for the purpose of minimalizing the interface.
The activation process starts with opening the Gallery app, and you have to go to the Albums tab and scroll to the bottom, and you'll find Hide Albums, which you want to put into active position, and then the system will ask you to set a password to access, and you can use the same password you used to unlock the screen, or you can create a unique security code.
☑️ Setup of a Hidden Album
Once you have access control over hidden files, it becomes intuitive. When you're viewing album thumbnails, you just pull down to open the password window, and this action hides the content from the casual eye.
⚠️ Warning: When you reset your phone to factory settings without first logging out of your Mi Account or deleting your password for accessing a hidden album, you risk losing access to your data forever.
To move existing photos to a secure area, select the desired images in the shared tape, click the "More" button (three dots) and select the "Add to Hidden Album" option, while the original will be removed from public access and moved to encrypted storage. If you decide to return the photo back, the procedure is similar, but already inside the hidden album itself.
💡
Use different passwords to unlock the screen and for a hidden album, which will create an additional layer of protection: even if someone recognizes your primary pin, they will not be able to access personal photos.
Hiding folders through File Explorer
If you want to hide not only media files, but also documents, archives or folders with application data, Xiaomi’s standard Explorer comes to the rescue. This tool allows you to hide entire directories, making them invisible in normal file system viewing mode. The mechanism of work here is different from the gallery, because it affects the structure of the device’s files.
To get started, open the Explorer app and go to Documents or Folders. In the upper right corner or in the settings menu (three bars or dots), find Hide Files. Activating this feature will require identification through a password or biometrics, similar to setting up a hidden album. Once enabled, a special folder will appear in the interface that is protected.
The tricky thing about the Explorer is that it doesn't just hide the folder icon, it changes file attributes or moves them to a restricted system directory, and files added to the hidden Explorer folder stop showing up in other applications, such as music players or video players, until you retrieve them back.
- 📂 Open Explorer and go to File Category.
- 🔒 Click on the menu and select “Hide Files”, then confirm the action.
- 📥 Move the required documents to the hidden folder that appears.
- 👁️ To see hidden files in normal mode, go back to the menu and turn off the display of hidden files.
It is worth noting that when you copy files to a hidden Explorer folder, the originals may remain in place if you use Copy instead of Move. For maximum privacy, always choose to move.
Second Space Mode for Total Insulation
The most radical and effective way to hide not just folders, but entire applications and their data is to use the Second Space function, which is not just hiding files, but creating a full-fledged second operating environment inside your smartphone. To the system, it looks like two different phones in the same case.
Activation of Second Space is done via the Settings menu → Special Options → Second Space. When you first start up, the system will suggest setting up a separate lock screen that will differ from the main one. For example, you can assign different fingerprints to enter the first and second spaces. When you touch the sensor with a certain finger, you will immediately be taken to a hidden profile.
In Space Two, you'll have a completely clean system: your Wi-Fi settings, your Google and Mi accounts, your apps, and of course your file system. The files stored here are completely invisible to your main profile. Even when you connect your phone to your computer in file transfer mode, the contents of Space Two won't show up unless you're logged in.
| Parameter | Main space | Second space |
|---|---|---|
| Access to files | Full access | Isolated. |
| Installed annexes | Independent recruitment | Independent recruitment |
| Notifications | Come to the main profile | They only come in when they enter. |
| Battery consumption | Standard. | Background processes can consume charge |
Switching between spaces is done quickly through a notification curtain or a special label on the desktop, ideal for separating work and personal life or storing highly sensitive information, but it is worth considering that having a second active profile can slightly increase battery consumption.
💡
The second space is the only way to make apps and their data completely invisible to the main user, creating the effect of two different smartphones.
Hiding system folders with.nomedia
For more advanced users who want to hide folders with media files from being scanned by the gallery, but leave them accessible through the file manager, there is a method using a special token. Adding a file named.nomedia to the directory tells the Android operating system that this folder does not have media files for indexing.
To use this method, you will need a file manager with access to hidden system files (for example, Total Commander or MiXplorer, since a standard Explorer may not show files that start from a dot). Create a new file in the desired folder and call it.nomedia (without extension).
This method doesn't password-protect files or encrypt them; it only hides them from being automatically displayed in a gallery and other multimedia applications. Anyone who has access to the file system and knows about the folder's existence will be able to open and view the contents of the folder, so it's a good way to organize file space, but not to provide security.
File name:.nomedia
Location: Inside a folder that you need to hide from the gallery
Effect: Files stop showing up in the galleryNomedia changes may not take effect instantly, sometimes requiring you to restart your device or clear the Media Storage app cache in your application settings so that the system can re-scan the file system and apply the changes.
Use of third-party safe applications
If MIUI is not enough, Google Play offers a variety of specialized applications to hide files, such as Calculator Vault, KeepSafe or Private Photo Vault, disguised as conventional utilities (calculators, voice recorders), but when you enter special code opens hidden storage.
The main advantage of these apps is that they can set a fake password, so if you're forced to unlock your phone, you can type in a code that opens up an empty or pre-prepared storage of unimportant files, while hiding real data, and many of them take a face picture of someone who has mistyped the password several times.
- 🛡️ Encryption: Files inside such applications are often encrypted, making them impossible to read without a password even when connected to a PC.
- ☁️ Cloud redundancy: Many apps offer automatic uploading of hidden photos to the cloud in case of a phone breakdown.
- 🎭 Masking: The app icon can look like a system utility or calculator without causing suspicion.
However, using third-party software carries risks: Unlike Xiaomi’s system solutions, data in third-party applications can be lost when you uninstall an application unless you set up a backup, and free versions of such programs are often overloaded with advertising, and paid ones require subscriptions.
Risks of using third-party safes
Access and data recovery issues
Despite the convenience of hiding features, users often face a situation where file access is lost, which can occur due to a forgotten password, a system failure, or a switch to a phone from another manufacturer. In the Xiaomi ecosystem, restoring access to hidden files is closely linked to a Mi Account account.
If you forgot the password from the hidden album but linked a Mi Account, you can try to restore access via i.mi.com or the Forgot Password feature on the input screen.The system will send the confirmation code to the linked phone number or email.However, if the account was not tied or the phone was reset to factory settings, the chances of recovery are minimal due to the high level of encryption.
⚠️ Note: Find Device will not help you recover deleted hidden files. Hiding files is a local operation, and without a backup in the cloud, Mi Cloud or Google Photos will not be able to return data after a reset.
When you switch to a new Xiaomi smartphone, to see hidden files, you will need to log in to your Mi Account and enable hidden album sync in the cloud settings. The files will download automatically. If you change the brand of the phone, pre-extract all files from the hidden album to the regular folder, otherwise on a new device (such as Samsung or iPhone) you will not be able to access them using standard means.
💡
Make regular backups of important hidden files to your computer or external hard drive. Don't rely solely on your phone's internal memory, as a physical device breakdown can permanently shut down access to data.
