Xiaomi, Redmi and POCO have powerful multimedia capabilities, turning into repositories of vast amounts of personal information. Often, there are situations when you need to remove certain videos from prying eyes, whether they are friends picking up a phone or children. The built-in shell tools MIUI and HyperOS allow you to do this without installing third-party applications, providing reliable data protection.
Android security, coupled with proprietary add-ons, offers multiple levels of content access. A hidden folder is not just a rebranded directory, but a secure space with encryption and password or biometrics, and understanding how this mechanism works will help you organize the file structure of your device.
In this article, we will take a look at all the ways video files can be hidden, and you will learn about the nuances of the Gallery and Explorer, and how to prevent the accidental deletion of important data when cleaning up memory. Local data protection is a basic skill that every smart device owner should possess.
Functional hidden folder in the Xiaomi Gallery
The main tool for working with media files in Xiaomi smartphones is the standard Gallery application. This is where the most convenient interface for hiding videos is implemented. To activate this feature, you need to perform a simple action: open the album and pull the list of albums down until the lock icon appears. Once you enter a password or scan your fingerprint, you will access the Hidden Album.
It's important to understand the difference between a normal deletion and a hidden folder. When you hide a video, the system changes its path in the file system and applies encryption. Standard applications don't see these files until the correct access key is entered, which ensures that even when you connect the phone to your computer in file transfer mode, the content remains inaccessible without authorization.
⚠️ Attention: When you transfer a video to a hidden album, the original file moves. If the process is interrupted due to memory shortage or battery discharge, the file may become corrupted.
The hidden album interface mimics the normal one, allowing you to sort files by date or create separate categories. However, the functionality is limited to viewing and deleting - you can't edit or share videos directly from the hidden album, you need to restore them first. Files in the hidden album are not synchronized with Mi Cloud unless you have a special option to encrypt the cloud.
- 🔒 Access to a hidden album is protected by a separate privacy password, different from the screen unlock password.
- 👁️ In a hidden album, you can hide not only videos, but also photos, notes and audio recordings.
- 📂 The function is available on all current versions MIUI HyperOS without regional restrictions.
Setting up access and security passwords
The security of your data depends on the complexity of the security installed. Xiaomi offers flexible settings for the Privacy Password. This is not the code you unlock the screen with, but a separate key used to access hidden files, hidden applications and On-Air mode (if configured).
You can set up biometric authorization to access hidden videos quickly, and fingerprints and facial recognition can make it much faster to view, eliminating the need to enter code every time, but remember that biometrics is a convenience, not absolute protection, and in critical situations, the system will still require a master password.

Don’t forget about password recovery via Mi. If you forget the hidden folder access code, the only way to get it back is to reset it through the linked account. Without this step, the data will be lost forever, as retrieving your privacy password through email without linking Mi Account is often impossible in new firmware versions.
- 🔑 The privacy password must contain at least 4 characters or 6 digits.
- 👤 Mi Account binding is required to recover a forgotten password.
- 🚫 After 5 failed attempts to enter a password, access is blocked for a certain time.
Hiding Videos Through Explorer and File System
An alternative way to organize files is to use the System Application Explorer, which allows you to hide not only media files, but also documents of all formats. The mechanism of operation is similar to the Gallery: in the list of file categories (Images, Videos, Documents), you need to swipe down to call the authorization window.
The Android file system has a peculiarity: files added to a hidden folder through Explorer disappear from the Gallery and vice versa if applications access the same encrypted data store. However, there are cases of desynchronization of indexes when the video is displayed in Explorer but not visible in the Gallery.
Where are the hidden files physically stored?
Hidden files are moved to the system folder MIUI_Gallery_Cloud It's closed to standard root-right viewing, and the files are renamed.enc or.mi, making them unreadable for third-party players without a decryption key.> When working with large amounts of data through Explorer, you should consider the speed of recording the drive. The operation of moving video weighing several gigabytes can take time. Interrupting this process through Task Manager can result in broken sectors or “phantom” files that take up space but don’t open. 📁 The Explorer allows you to hide folders as a whole, not just individual files. 🔄 Synchronization between the Gallery and the Explorer is automatic, but with a delay. 🗑️ Deleting a file from a hidden folder in Explorer irrevocably erases it from the device. Users often wonder which way to store hidden videos is preferable. In fact, both methods use the same encryption mechanism at the system level, but differ in interface convenience and additional features. The choice depends on your habits and the type of files you hide. The gallery is focused on visual content and provides preview, slideshow and basic editing (after recovery). ☑️ Storage security Check Complex password Installed BiometricsInstalled Mi AccountAccess Free space Files checked for playback: 0 / 5 It is also worth noting the impact on performance: the presence of a huge number of files in a hidden folder (more 1000 The explorer can slow down the opening of the Gallery app when entering a hidden album. The explorer handles larger file lists more stable, as it does not attempt to generate previews for each item. Characteristics Gallery Explorer Support for Video formats, Photos All types of files Viewing convenience High (grid, preview) Average (list) Speed Depends on the amount of media Stable editing Ability Basic No problem solving: Sometimes users are faced with a situation where the video refuses to hide or disappears after moving. Most often, the reason is a lack of space, and the operation of hiding is actually copying a file to an encrypted area and deleting the original, and if there is not enough memory for temporary duplication, the process will end in error. Another common problem is the conflict of application versions. MIUI or HyperOS old cached Gallery data may cause crashes, in which case you need to clear the application data through the settings menu (Settings) → Annexes → All applications → gallery → This won't delete your photos, but it will reset the settings for displaying albums. ⚠️ Warning: Do not attempt to rename files inside a hidden folder through third-party root-access file managers.This will violate the integrity of the media database and cause the Gallery to stop seeing the contents even though the files will physically be in place. It's also worth checking your power saving settings. Aggressive energy saving modes can block background encryption processes. If you're moving a big video, try turning off the power saving mode and restart the device. 📉 Lack of memory is the cause №1 Mistakes When Hiding Files. 🐛 Firmware bugs are solved by cleaning the cache or updating the software. ⚡ Energy saving can interrupt long-term recording operations. Recovery and management of hidden data Returning video from a hidden folder to the public domain is as easy as hiding it. In the Gallery or Explorer interface, you need to select the files you want, click the menu button, and select the option “Delete from Hidden Album” or “Restore”; the files will return to the original directories they were in before the hiding. When you delete a video from a hidden album, the system requests confirmation of the operation, warning you that you can't recover through the cart, and this level of security is higher than with a normal deletion, where the file is in the basket for another 30 days. Backup via Mi Cloud does not include hidden files by default, so to keep them safe, you need to manually transfer them to a regular folder before the backup or use local backup with encryption. 💡A hidden folder is a convenient tool for quick protection from prying eyes, but not a substitute for full-fledged encryption of data for transfer to third parties (FAQ) Can you recover a video that's been deleted from a hidden album?

Are you seeing hidden videos when you connect your phone to your computer? No. USB file transfer mode (MTP) The computer sees only open memory, the hidden data is only accessible through the interface of the smartphone itself after authorization, do hidden videos take up space in the Mi Cloud cloud? By default, the hidden album sync with the cloud is disabled. However, in the hidden album settings, you can enable the sync option, then the videos will be uploaded to the cloud in encrypted form and take up space in your Mi Cloud storage. What will happen to the hidden videos when you update the firmware (OTA) Hidden files are saved and remain available after rebooting. Problems can only occur when switching between major versions of Android (for example, from Android 13 to 14) or when installing custom firmware, which may require re-authorization.
