Modern Xiaomi smartphones offer huge opportunities for multimedia and work, but even 256 or 512 GB of internal memory can suddenly run out. Users often face a situation where the system reports overflowing and standard cleaning methods do not give visible results. The question of how to enter Xiaomi memory at a deep level becomes critical to maintaining the performance of the device.
In this article, we will explore not only the standard paths through settings, but also more advanced methods of accessing the file system. You will learn how to analyze hidden partitions, remove system debris and safely manage data without losing important information. Understanding the structure of the MIUI or HyperOS storage will allow you to extend the life of the gadget.
Donβt ignore the space-short signals, as this can lead to a freeze in the interface or the inability to install updates.Weβll look at tools that help you become a full owner of your device, rather than just a user limited by standard resolutions.
Standard access through the settings menu
The safest and most accessible way to view the contents of the storage is to use the built-in operating system tools, so you go to the main menu and select Settings. Then scroll down to About Phone, where you can see the device information.
In the window that opens, you'll see a graphical display of the occupied space, and you'll click on it and you'll be taken to a detailed view, where the space is broken down into categories: apps, images, videos, documents, etc. The Xiaomi shell Android system automatically sorts files, making it easier to find large objects.
It also has a cleanup feature that automatically finds cache and temporary files, but it is worth noting that this method only shows user data and does not give access to system partitions hidden from the eyes of the average user.

The standard menu only shows user data and does not allow you to delete system files without root rights.
For more in-depth analysis, it is recommended to use the built-in Explorer. Find the Explorer (or File Manager) application on the desktop. At the bottom of the screen, select the Analyzer or Folders tab to see the directory structure in /storage/emulated/0.
Using the Engineering Menu for Diagnostics
There is a hidden partition of the system, known as the engineering menu, that allows you to access technical memory information. To go there, open the Phone app and type the combination ##6484##. Some models may have different code, such as #4636## for testing.
In the CIT (Customer Information Test) menu, you can find memory tests that show the actual state of the drive, the number of rewrites and the presence of (bad) sectors, which is useful if the phone has started to work slowly or often freezes.
β οΈ Note: Making changes to the engineering menu without an accurate understanding of the processes can cause communication modules or cameras to malfunction.
The engineering menu also allows you to check the type of memory you have installed (eUFS or eMMC) and its speed, which is important when buying a used device or diagnosing after a fall. MIUI information is not available.
Advanced analysis via ADB and computer
Deep immersion in the file system requires a computer connection and USB debugging, a technique that allows you to see hidden folders that are not displayed in a standard conductor and manage them with shell rights.
First, activate Developer Mode. Go to Settings β About Phone and quickly click 7 times on the MIUI Version (or OS Version) bar. After the notification "You became a developer" appears, go to Additional β For Developers and turn on the USB Debugging Toggle.
Connect your smartphone to your PC with a cable. On your computer, install the Android Debug Bridge (ADB) platform. Open the command line and enter a command to check the connection:
adb devicesThe phone will have a request for debugging permission β confirm it. Now you can display a list of all files and folders, including system ones. For example, the command adb shell ls -l /data will show the contents of the protected data partition (root required for full access).
βοΈ Preparation for work with ADB
With ADB, you can not only view, but also force the removal of undeleteable system applications (bloatware), freeing up space. However, be careful: removing critical components can lead to a bootloop.
Working with root rights and file managers
Full access to all memory partitions, including /system, /vendor and /data, is only possible if superuser (Root) rights are available.
Once root access is available, the best way to log in to memory is with an advanced file manager, such as Root Explorer or MiXplorer, which allows you to mount partitions in read/write mode.
| Memory section | Description | Can I remove it? |
|---|---|---|
| /system | Android and MIUI system files | Experienced (high risk) only |
| /data | User data and applications | Selectively (appendix data) |
| /cache | Temporary system files | Safe (cleansed itself) |
| /sdcard | Internal memory (photos, music) | Yeah (personal files) |
When working with root access, it is critical to understand the difference between symbolic links and real files. Deleting the system library in /system/lib can make the phone unusable. Always back up (TWRP or Mi Flash) before tampering.
What is the Data section in Xiaomi?
Cleaning up hidden debris and app cache
The bulk of memory is often occupied not by files, but by bloated caches of messengers and social networks. Telegram, WhatsApp and Instagram can take up tens of gigabytes, storing old media files in hidden folders.
To find them, use Explorer and follow the Android/data path. This is where the folders of all installed applications are located. For example, Telegram cache is often located on the path org.telegram.messenger/files. It is safe to remove the contents of the cache folder inside the application directories.
Also worth looking at is the.thumbnails folder at the root of the internal memory (hidden folder, turn on hidden files) that stores thumbnails of images from the gallery that can grow to huge sizes, and cleaning this folder regularly frees up space.
β οΈ Attention: Folder Android/obb It contains cache data for games, and if you delete files from here, you'll have to download them again when you start.
To automate the process, you can use the built-in Security app from Xiaomi. It can find large files and duplicates, but sometimes misses a deep cache, so manual control through the file manager is necessary.
Frequent problems and their solution
Users often encounter an error called βInsufficient Memoryβ even when there is free space, which may be due to a /data partition overflow or file system errors, in which case rebooting to Recovery mode and selecting the Wipe Cache Partition (not to be confused with a full reset) help.
Another problem is the inability to write a file to a memory card or internal memory, often solved by checking access rights in application settings or formatting the drive into an exFAT or NTFS file system (with support).

If the phone says "Memory is full", but there is free space, try to turn off the device, remove the device. SIM-card and memory card (if any), then turn it back on.
In rare cases, you need to flash your device and clean all partitions, which is an extreme measure that puts your phone back into a store-like state. Before you do that, make sure you save important data to your cloud service or computer.
