How to Make a Secret Folder on Xiaomi: A Complete Guide to Hiding Files

The modern smartphone has become a digital repository of our personal lives, where not only work documents, but also confidential photos, passport scans or private correspondence are stored. Owners of Xiaomi, Redmi and Poco devices often wonder how to securely hide this data from prying eyes without installing dubious applications from third-party sources. Fortunately, the MIUI shell and the new HyperOS offer powerful built-in tools to solve this problem.

Unlike standard Android launchers, Xiaomi's system allows you to create isolated spaces for files that are protected by an additional password or biometrics.hidden_files This is not displayed in the gallery and conductor without authorization, and provides a high level of privacy even when the main screen of the device is unlocked.

In this article, we will discuss in detail the standard methods of data hiding that work on most current models of the brand. You will learn how to use the function “Hidden albums”, how to configure “Second space” for complete data isolation and what are the nuances of working with the file system in new versions of firmware.

Using the built-in hide album function

The easiest and fastest way to hide photos and videos is to use the standard Gallery app, which is ideal if you need to quickly remove a few shots from outsiders without creating complex folder structures. First, open the Gallery app and go to the Albums tab.

Scroll down the album list, and you'll see the Hide Albums option or the lock icon, and once you activate this feature, the system will ask you to give a password or use your fingerprint to access it, and it's important to note that the hidden album password may be different from the screen unlock password, which adds an additional layer of security.

To move the photo to a hidden area, highlight the desired images, click the "More" button (three dots) and select "Add to Hidden Album." The source files will be removed from the shared tape and moved to a secure storage.

• 🔒 Access to hidden photos is protected by a separate PIN-code-key.
• 📸 Hidden albums are not visible in the previews of apps and widgets on the desktop.
• ☁️ When synced with Mi Cloud, hidden albums are also encrypted and uploaded to the cloud.
• 🔄 Recovering a photo back to the shared gallery takes a few seconds through the control menu.

⚠️ WARNING: When you clean up the Gallery app data or reset your phone settings without first unloading, files from the hidden album may be irretrievably lost.

Set up the Second Space for Total Insulation

If you want to not just hide files, but create a completely separate environment with other accounts, applications and files, the Second Space feature is the perfect solution. It's the virtual machine analog built right into the MIUI system. The second space works as a separate smartphone inside your main device.

To activate, go to Settings → Second Space and click “Enable.” The system will prompt you to create a new password or set up a fingerprint sign-in that will immediately open the second space, bypassing the main screen, which allows you to keep personal and work (or secret) content completely separated.

All files downloaded or created in the second space are stored in an isolated partition of memory, and even if you connect your phone to your computer via USB, you won't see the files in the second space until you switch to it and choose the file transfer mode, which makes it extremely effective for storing sensitive information.

• 📱 Complete application isolation: messengers and social networks in the second space are not visible.
• 🔋 The function consumes additional battery and RAM resources in the background.
• 🔄 Transfer of files between spaces is carried out through a special folder-gateway.
• 🛡️ Resetting the main space settings does not affect the data in the second profile.

Hiding Files through File Manager and Explorer

The Explorer app (or File Manager) also allows you to hide not only media files, but documents of any format, which is convenient for hiding folders with documents, archives or audio files. Open the application and go to the Documents or Folders category.

Press and hold your finger on the folder you want to hide, then select the Hide option from the menu. The system will warn that the folder will only be accessible through a special input in the Explorer settings. To view hidden folders, you need to go to the Explorer settings and activate the Show Hidden Files switch by entering the password.

Technically, files are marked with a system stealth flag, but not encrypted with an additional algorithm, as in the second space, so security here is ensured mainly by the software restriction of visibility in the standard interface.

⚠️ Note: Files hidden through standard Explorer may become visible when connecting your phone to your PC in debugging mode or when using root-righted file managers.

Advanced methods: folder.nomedia and renaming

For users who want to hide files from being scanned automatically by media players and a gallery, there is a method to create a tag file: Create a file in the right folder called.nomedia (required to have a point at the beginning), which causes the Android system to ignore the contents of the folder when updating the media library.

It doesn't require passwords or system settings, it works at the file system level. However, it doesn't protect data from being viewed through any file manager if the user knows where to look, it's more of a way to keep the gallery clean than a method of cryptographic protection.

You can also rename a folder by adding a dot at the beginning of the name (e.g.,.Secret). Linux-like systems that run Android are considered hidden by default. To see them in advanced Explorers, you need to enable the option "Show hidden files."

• 📁 The method is effective for hiding folders with memes, screenshots or background music.
• 🔍 Files remain visible for specialized document scanner applications.
• ⚙️ No need to include additional services or battery consumption.
• 🚫 Does not protect data when physically accessing the device’s file system.

Security and Recovery of Hidden Data

Using the hidden features requires responsibility. Forgetting the password from a hidden album or second space, you risk losing access to information forever, as password reset via Mi Account is not possible in all regions and firmware versions. Regular backup is critical.

When selling a phone or transferring it to another user, it's not enough to simply delete files from hidden folders. Data can be recovered by specialists. The only reliable way is to completely reset to factory settings, cleaning all user data, including encrypted sections of the second space.

It is worth considering that some banking-type applications or corporate clients may block work on devices with active second space or/root-rights, considering it a violation of environmental safety.

💡

Before selling your phone, be sure to delete Second Space through settings, rather than just drop the phone, otherwise the data may remain in the hidden memory partition.

⚠️ Note: When updating the firmware MIUI before the major version (for example, with MIUI 13 on MIUI 14 or HyperOS) Second space settings can be reset and files deleted. Always backup before upgrading.

💡

The most reliable way to hide data is to combine Second Space with a complex password that is not associated with your primary Google or Mi Account.
