Xiaomi smartphone owners often face a situation where important videos disappear from view, although they occupy space in the device’s memory.This can be caused by a system error, accidental transfer of files to system folders, or using the Hidden Folder feature to protect content from prying eyes. Understanding the structure of the MIUI and HyperOS file system is the first step to successfully solving the problem.
There are several ways to detect hidden media content, ranging from standard operating system tools to advanced file manager search methods. It is important not to panic, as in most cases the data is not destroyed, but simply becomes invisible to the standard Gallery. In this article, we will discuss each method in detail so that you can regain access to your records.
Before you start complex manipulations, you need to make sure that files have not been permanently deleted or transferred to cloud storage. Xiaomi’s modern shells have many layers of protection and system filters that can hide content for various reasons. We will look at both software solutions and manual search methods.
Use of the built-in Hidden Folder function
The most common reason for video loss is when a user or application moves it to a secure container. Hidden Folder in MIUI allows you to hide photos, videos, audio files and notes behind a password or a pattern lock. To check if your files are there, open the Gallery app.
At the top of the album list screen, swipe down (pull the album list down). If the feature is activated, a field will appear to enter your password or fingerprint. Once you have successfully logged in, a separate space will open up where sensitive videos could have been moved. If you haven't previously set a password, the system will prompt you to create one when you first log in.
⚠️ Note: If you forgot the password from the hidden folder and did not link your Mi Account to restore, access to the content will be lost without the possibility of resetting.
Inside the hidden folder, files are sorted by type. Go to the video tab to check if they are available. From here, you can move files back to the public by selecting the option "Delete from the hidden folder" or "Show" and check the folder's settings, where you can see the list of hidden applications, if any.
Sometimes users forget that they have activated automatic hiding for certain applications or file types. Check the privacy settings in the Application Protection section to make sure that Gallery or Explorer does not block access to content.
💡
A hidden folder is not deletion, it's encryption of access. Files take up space in memory, but don't show up in shared lists without authorization.
Search through Explorer and System Folders
If you don't see videos in the Gallery, it doesn't mean they're not on the device. Often files lose their metadata or end up in folders that the default system hides from the media scanner. For deep search, you need to use the built-in File Manager app. Run it and go to view all files.
From the top menu, select the Video category or search for the file extension. Type.mp4,.mkv or.mov. The Explorer will display all the video files found in internal memory and on the microSD card, regardless of their location. Pay special attention to the folders with the prefix. (dot) as they are considered hidden in the Linux/Android system.
- 🔍.thumbnails folder – cached thumbnails can be stored here, but sometimes the originals if there is a failure.
- 📁 folder DCIM/.thumbnails — Standard location for temporary camera files, check its contents.
- 🗑️ Recycle Bin - Files could have been deleted accidentally and lie there for up to 30 days.
It’s also worth checking the folders of messengers like WhatsApp, Telegram or Viber. Videos received through these apps are often saved in their own directories, such as Android/media/com.whatsapp. If the file was saved manually, it could get lost in the depths of the directory structure.
What to do if the file is 0 bytes in size?
Analysis of the.Trash folder and recent deletions
Modern versions of the MIUI shell are equipped with a Trash function that prevents irretrievable data loss. When you delete a video from the Gallery, it is not erased instantly, but moved to a special buffer where you store 30 days. To find deleted files, open the Gallery and go to the Albums section.
Scroll down the album list, and you'll find a folder called "Deleted" or "Basket," and you can have hundreds of files that you accidentally deleted weeks ago, select the videos you want, and click "Restore" to return them to the main album.
It's worth noting that cleaning the shopping cart in the Gallery doesn't always sync with the shopping cart in Google Photos or the Mi Cloud. If you've used sync, check the web version of the cloud service. Sometimes the file is deleted locally but remains in the cloud, or vice versa.
| Location. | Storage period | Recovery |
|---|---|---|
| Gallery basket | 30 days | Instantly. |
| Google Photos (Cloud) | 60 days | Through browser/application |
| Mi Cloud | 30 days | Through account settings |
| Third-party annexes | Depends on the software. | Inside the app |
If the Deleted folder is empty, then the files have been permanently erased or their storage period has expired, in which case, standard OS methods will not return them, you will need to use specialized software to recover data, as discussed below.

Enable sync with Mi Cloud or Google Photos right now.This will back up your videos even if they are deleted from your phone.
Checking the display settings and media scanner
Sometimes video files are physically on the device, but the system does not see them due to a failure of the media scanner or display settings. MIUI has an album hiding feature that allows you to remove folders like Screenshots, Downloads or cached game folders from view.
Open the Gallery, go to the Albums tab, and click on the menu icon (three dots or gears). Find Hide/Show albums. Make sure the switches in front of the folders you're interested in are active. If the album is hidden, its contents won't show up in the general stream.
Another reason could be the.nomedia file, which is a hidden system file that prevents the system from scanning it for media files, and if you accidentally created one in the video directory, or if it appeared after installing an application, the Gallery will stop seeing the videos.
- 📂 Go to Explorer and enable the display of hidden files in the settings.
- 🔎 Find the.nomedia file in the missing video folder.
- ❌ Delete this file and restart your smartphone to restart the scanner.
It’s also worth checking if the phone is in a Traffic Savings or Data Limit mode, which can block the download of preview videos from the cloud, creating the illusion of no video.
Data recovery by third-party utilities
When Xiaomi's built-in tools don't help, third-party data recovery apps come to the rescue, and the effectiveness of these programs depends on whether memory sectors have been overwritten with new data, and the sooner you start deletion recovery, the better the chances of success.
One popular solution is the DiskDigger app, which works with and without root rights (in limited mode). Deep scanning may require superuser rights that can be obtained through unlocking the bootloader, although it is a complex and risky process.
⚠️ Warning: Installing recovery apps directly on internal memory may result in overwriting deleted files.It is better to use the PC version or run a scan from a memory card.
To connect your phone to your computer, use USB debugging mode. Enable it in the Developer Menu (to open the menu, you need to click on the build number in About Phone 7 times). Then connect your smartphone to your PC and run the reversing program on your computer.
adb devices
adb shell ls /sdcard/DCIMThis command, via the Android Debug Bridge (ADB), will allow you to check the availability of files at the system level, even if the Gallery does not show them, and if the command line sees files, then the problem is purely software in the MIUI interface.
Loss prevention and memory management
To avoid video loss situations in the future, it is important to properly organize data storage. Xiaomi smartphones internal memory is faster and more reliable, but it is limited. Regularly cleaning the cache and transferring archived videos to an external medium or to the cloud is the best strategy.
Use the Cleanup feature in the Security app to remove duplicate videos. Often users film the same event multiple times, forgetting to delete the failed take, which frees up space and makes navigation easier.
- ☁️ Set up automatic upload in Google Photos when connecting to Wi-Fi.
- 💾 Buy a high-quality microSD card with high speed class (U3/A2).
- 🔄 Check the Downloads folder once a month and delete unnecessary files.
Also keep an eye out for system updates: newer versions of MIUI and HyperOS often fix file system bugs that may have caused files to disappear. Don't ignore notifications about available security updates.
