Xiaomi smartphone users often face the situation when you need to hide confidential photos, documents or videos from prying eyes. The standard gallery and file manager can show all the contents of memory, which is not always convenient if the device is used by other family members or colleagues. The MIUI and HyperOS operating system implement a special data protection mechanism, which is often called “Personal folder” or “Hidden Space”.
But finding this partition isn't as easy as it might seem. Unlike regular apps, it doesn't have to be accessed on the default home screen, and requires specific actions or gestures. Understanding the structure of the Android file system and the features of the Xiaomi shell will help you not only hide files, but also manage them competently.
In this guide, we will take a look at all the ways to detect and activate secure storage. You will learn about native security tools, hidden directories in the system and cloud services that can serve as a personal archive. Data security is a priority for any smartphone owner, and using these features correctly will be the first step to protecting your digital life.
Use of the “Hidden Files” function in the Explorer
The most common way to hide data on Xiaomi devices is to use the built-in Explorer feature, which does not create a separate visible folder in the shared list, but encrypts the content and hides it in the system partition, which is only accessible after you enter a password. To activate this mode, open the standard Explorer application and go to the Images or Documents category.
Next, swipe from top to bottom across the screen, simulating the “update” action. If the function has not been previously configured, the system will prompt you to create a password and a check question. Once you set the security at the bottom of the file list, the Hidden Files section will appear, and this is where your personal data is stored, and it will not be displayed in the gallery or other applications without authorization.
It is important to understand that files moved to this partition are physically left on the device, but their metadata is hidden from the system’s media scanner, which means that thumbnails of photos will not be visible, and notifications about new files in messengers may not come if they are saved to a hidden area.
☑️ Set up a hidden folder
Note that when you reset your settings to factory settings without first logging out or decrypting hidden files, access to them can be lost forever. Xiaomi’s security system ties the encryption keys to the current configuration of the device, so backing up passwords is a critical step before any manipulation of system settings.
Searching for system directory.MIUI_Gallery_Cloud
The Android file system on which it is based MIUI, There are many service folders that start with a dot, and they're considered hidden by default, and they don't show up in standard browsing mode.MIUI_Gallery_Cloud, which is often used to sync albums and may contain cached versions of your personal photos.
To see these objects, you'll need a file manager with extended access rights or the "Show hidden files" option enabled in the Explorer settings. The path to this directory usually looks like /storage/emulated/0/DCIM/.MIUI_Gallery_Cloud. Inside may be subfolders with the names of the albums you created in the gallery.
- 📁 The point at the beginning of the name is a standard marker for hiding a folder in Linux and Android.
- 🔒 Lack of access – some system folders may not be readable even with user rights.
- 🔄 Sync – The contents of this folder can automatically upload to the Mi Cloud.
It is not recommended to delete or modify files in the system hidden folders without understanding their purpose. This can lead to incorrect gallery operation, loss of thumbnails or sync errors with the cloud service. If your goal is simply to free up space, you should use built-in memory cleaning tools.
⚠️ Warning: Direct editing of files in hidden system directories can compromise the integrity of the database of media files.
Why can a folder be empty?
Personal folder in the Mi Drive (Mi Cloud) app
Xiaomi’s cloud storage, known as Mi Drive, is also noteworthy, and in some regions and firmware versions, it is integrated directly into the system and offers a Private Folder feature inside the cloud, which allows files to be stored not on the physical media of the phone, but on the company’s servers, protected by an additional password.
To access this functionality, you need to open the Mi Drive app or go to the Mi Cloud settings via the phone's settings menu. Here you will find a section offering to create a secure space. Files placed there will only be available after you enter a separate password, which may differ from the unlock password of the screen.
Using a cloud-based personal folder has its advantages, especially if you change devices frequently or fear losing your smartphone physically, and even if your device is damaged, your data will remain safe on the server, but you should keep in mind that the amount of free storage is limited, and you will have to pay for expanding the space.
The speed of access to these files depends on the quality of the Internet connection. If you are in a bad network reception zone, downloading large-scale videos from your personal cloud folder can take considerable time.
Create a secure profile through the Second Space
MIUI's Second Space is a powerful tool that creates a completely isolated environment inside a smartphone. In fact, you get two phones in one: the main and the guest (or personal) phone, the most radical and reliable way to hide not just a folder, but entire apps and their data.
You can activate this function via the Settings path → Additional Settings → Second Space. Once you create a profile, you can switch between the main and second space using a special shortcut on the lock screen or fingerprint. All files, installed applications and accounts in the second space are completely independent.
Inside the second space, you can create your "personal folder" in any convenient way, and it will be completely invisible to the user of the main profile. Even when you connect the phone to the computer in file transfer mode, the contents of the second space will not appear without changing the context.
| Characteristics | Hidden files | Second space |
|---|---|---|
| Level of protection | Medium (password to folder) | High (separate OS) |
| Visibility of applications | Appendices visible | Applications hidden |
| Impact on the battery | Minimum | Medium (background processes) |
| Difficulty setting up | Low. | Medium |
The second space is especially relevant if you want to separate work and personal data, for example, in the main profile, messengers for work can be installed, and in the second, personal social networks and banking applications, which ensures maximum privacy and order.
Working with an Android folder and accessing application data
In the newer versions of Android (11, 12, 13 and above), which are installed on modern Xiaomi smartphones, access to the Android system folder and its data subdirectories was significantly limited for security reasons.
Now, a standard file manager can show these folders empty or require special permission at each login. To access personal application files in this zone, you sometimes need to use third-party SAF (Storage Access Framework) Explorers or connect to a PC.
- 📂 The Data Path: /storage/emulated/0/Android/data/.
- 🛡️ Restrictions: the system blocks direct access to other people’s application data.
- 🔍 Media Search: Often the files you search for are in the files subfolder inside the application directory.
If you’re trying to find personal correspondence or files saved from Telegram or WhatsApp and standard methods don’t work, try using the built-in export functionality in the application.
💡
Use the Cleanup feature in the Security app to find large files that take up space but are not visible in standard folders.
Restoring access and solving problems
Often users forget the password from the hidden folder or lose access to the account through which it was created. In the case of native hidden Xiaomi files, password reset is possible only through the answer to the control question you asked when you created. If the question is forgotten or the answer is wrong, the data, alas, will not be restored due to the encryption used.
For cloud-based personal folders, the recovery process is simpler: just use the standard procedure for retrieving a Mi Account or Google Account via email or phone number, and once you log in to your account on a new device, all the data in your Mi Drive personal folder will be available.
If hidden files are missing after a system update, check the display settings in Explorer. Sometimes after a major MIUI update, privacy settings may be reset, and the hidden file section simply stops showing until you re-authorize.
⚠️ Warning: There is no universal master password or code to unlock hidden Xiaomi folders.Any programs promising to do so are likely malicious.
💡
The only reliable way to not lose access to your personal folder is to remember your security question and password, or use cloud sync with a reliable account.
