Owners of Xiaomi, Redmi and POCO smartphones often face the need to make room for memory or find long-lost documents.The MIUI shell and the new HyperOS have a complex directory structure where system files and user data can be hidden from the eyes of the average user. This is done to protect important system components from accidental deletion, but sometimes prevents you from finding the right one.
Understanding how the Android file system works on Android devices allows not only to clean up, but also to speed up the work of the gadget. The standard interface does not always display all the contents of the storage, so you need to use special tools or change the display settings. In this article, we will discuss all the ways to detect and control hidden objects.
Before you start manipulating system directories, it is important to be aware of the risks: removing the wrong elements can cause malfunctions in applications or the operating system itself. Hidden files often contain program configurations, cache and temporary data necessary for the correct functioning of the software.
⚠️ Note: Be extremely careful when deleting files in system folders. Deleting objects with the ".." prefix or from the Android directory can cause app settings to lose.
Configure the display of hidden objects in a standard conductor
The easiest way to see hidden elements is to use Xiaomi’s built-in Explorer tool, which hides system folders and files that start from a point by default so as not to overload the interface. To change this behavior, you need to go to the settings of the application itself.
Open the Explorer app and go to the Overview tab or click on the menu icon (three bars). In the list that appears, select Settings. Here you are interested in the option "Show hidden files." By activating this switch, you will access previously invisible directories.
Once this function is enabled at the root of internal memory and on the SD card, folders that start with a dot (e.g.,.thumbnails) will appear, and system directories that are usually hidden will also be visible, allowing you to manually control the contents of the storage.
💡
If the standard Explorer doesn’t show the files you want even after you turn on the option, try restarting the device. Sometimes the interface cache prevents you from updating the list instantly.
It’s worth noting that some system partitions will still be unavailable for viewing without root rights, a security restriction on Android that prevents the user from modifying critical components to run the OS.
Finding hidden folders through your computer
If the smartphone interface seems inconvenient to work with a lot of data, you can connect the device to the computer. When connecting over USB, you need to select the MTP file transfer mode. On Windows, hidden folders can also be invisible by default.
To see all files on a Xiaomi connected through Windows, open “This Computer” and go to the folder properties (via the View tab at the top of the Explorer panel). In the window that opens, look for the View section and check the box opposite to “Show Hidden Files, Folders and Disks.”
Once you have the settings, all the hidden directories on your smartphone will be displayed on your screen, and they will look translucent, and this is a convenient way to mass-copy or delete data, because the keyboard and mouse provide faster speeds.
☑️ Checking the connection to the PC
Only the user’s internal memory and external map will be available.
Use of Third-Party File Managers
Staff tools don’t always have enough functionality for advanced users, and third-party file managers like Total Commander, Solid Explorer, or FX File Explorer provide more flexible tools for working with hidden data.
These applications often have a built-in system file display feature without having to change global settings, and they also allow you to sort files by size, date of change or type, making it easier to find “heavy” hidden objects taking up space.
Some managers support access to the root file system if the device has superuser rights, which allows access to all memory areas, including those where the logs and databases of the MIUI system services are stored.
When using third-party software, pay attention to the permissions requested. The file manager does not need access to contacts or a microphone to work with the file system. Excessive requests may indicate hidden data collection.
Analysis of system folders and junk files
A smartphone accumulates many temporary files, often hidden in folders with names like.cache or within application directories, and understanding the structure helps to safely clear memory.
The Android folder, which contains data and obb subfolders, which store game and application data, can cause content to be deleted, or it can cause game progress to be reset or program settings to be lost.
And there are also.thumbnails folders that store thumbnails of gallery images, which can take several gigabytes, and can be deleted, but the system will recreate them the next time you open the gallery.
⚠️ Attention: Folder.MI The data contains data from the Xiaomi Cloud service, which can disrupt the synchronization of photos and contacts.
For safe cleaning, it is better to use the built-in Cleanup tool in the Security app, which automatically detects secure cache and residues from remote applications without affecting important hidden configurations.
Table of the main hidden directories Xiaomi
Below is a table describing the most common hidden folders that can be found on Xiaomi, Redmi and POCO devices.
| The name of the folder | Description of the contents | Can I remove it? |
|---|---|---|
| .thumbnails | Photos and videos from the gallery | Yes (recreated) |
| .cache | Temporary data of various applications | Yeah (makes room) |
| .MI | Sync files with Mi Cloud | No (risk of data loss) |
| Android/data | Data of installed applications and games | Only specific applications |
| .Trash | Removed File Recycle Bin (in some versions) | Yes (final removal) |
Knowing the purpose of these directories helps avoid errors, for example, cleaning the.thumbnails folder can temporarily speed up the gallery, but when it first starts, it will again start consuming the CPU resources to generate thumbnails.
💡
Regular cleaning of the folder.thumbnails and the messenger cache is the most effective way to free up space without deleting personal photos.
Security and concealment of personal data
The file hiding feature works the other way around: you can hide your personal data from prying eyes. The MIUI shell has a built-in Hide Files feature that moves selected objects to a secure area.
To access these files, you need to enter a special password or fingerprint that was set when you set up the privacy protection function, and they are located on a path that does not appear in normal viewing mode.
This feature is recommended for storing scans of documents, personal videos or financial information, and even if the phone falls into the wrong hands, you will not be able to access this data without a password.
How do I turn on file hiding?
Remember that when you reset your phone to a factory setting, all hidden files will be permanently deleted along with the rest of your data. Always back up important information.
