Users of Xiaomi, Redmi and Poco smartphones often face the need to make room or find an application installation file. Understanding where these programs are physically located is key to managing the device’s memory correctly. In the Android operating system, which runs the MIUI shell or HyperOS, files are distributed according to a strict logical structure.
Unlike computers where the user is used to seeing all programs in the Program Files folder, on mobile devices, the path to data is often hidden from the eyes of the average user. However, when you access hidden directories or use special tools, you can see that applications take up not only visible space, but also reserved system partitions. Android file system divides data into user and system, which ensures the stability of the gadget.
In this article, we will discuss in detail where exactly Xiaomi stores applications, how to find them. APK-You will learn to distinguish between user data and system files, allowing you to efficiently clean memory without risking damage to the operating system.
Internal memory structure and system partitions
Xiaomi’s internal memory is a complex structure divided into several logical parts. The main part that is available to the user is usually labeled /storage/emulated/0. This is where your photos, downloads and application installers are stored. However, the executable files and libraries themselves are often located deeper.
The system partition where the default apps are installed is often hidden from standard file managers without obtaining Root rights.This is done for security reasons so that the user does not accidentally delete critical Android components. Apps installed from Google Play or GetApps prescribe their data to special directories, access to which is restricted by access rights.
⚠️ Note: Attempts to manually delete files from system partitions (e.g, /data/app) without understanding their purpose can lead to inoperability of the smartphone or endless reboot.
To navigate the file system, advanced file managers such as MT Manager or FX File Explorer are best used, allowing you to see hidden folders and understand the real weight of each component. Xiaomi’s standard conductor shows only the tip of the iceberg, hiding technical details.
Android folder: data storage and cache
The most important directory for the average user who wants to clean up the space is the Android folder at the root of the internal memory, which stores all the installed applications' data, their cache and temporary files, and when you delete the applications through the settings, this folder does not always clear completely, leaving "junk".
Inside the Android directory, you'll find two main subfolders: data and obb. The first contains databases, settings, and program logs. The second is designed for heavy game files such as textures and audio tracks. Deleting the contents of the obb folder will cause the game to stop running and require a re-jump of resources.
- 📂 data – here lie personal application settings, save progress and authorization tokens.
- 🎮 obb – storage of additional files for games and heavy programs with graphics.
- 🗑️ cache – temporary files that can be deleted, but they will be created again the next time you run them.
In modern versions of Android 11 and above, access to the Android/data folder is limited, the security system prevents file managers from viewing the contents of folders of other applications, this is done to protect the user's personal data from spyware.

If you decide to manually clean this folder, be prepared to reconfigure the applications. Cache can be cleaned safely, but account data is best left unchecked. Regularly cleaning the cache helps speed up the device if the memory is more than 90% full.
Wherever APK-file
Many users search for an installation file (APK) of an already installed program to pass it to a friend or save a backup. Xiaomi defaults to not save installers after the installation is completed by removing them from the download folder.
The way APK-System and user applications files are usually located at the address /data/app. In this directory, each program has a folder with the name of the package, for example, com.android.chrome. base.apk or multiple files with the.apk extension if the application is divided into modules (Split APKs).
For extraction APK Without superuser rights, you can use the built-in function MIUI In the standard menu of Xiaomi applications, the option "Create a shortcut installation" is sometimes available, but it does not work for all programs. APK-extractor.
☑️ Pre-deletion check APK
Use of the ADB-The team also allows you to pull out APK-It's a professional method that requires you to connect to a computer. USB The adb pull command copies the file from the system partition to the specified folder on the PC.
System applications and hidden partitions
Xiaomi’s factory applications, such as Security, Themes or Mi Video, are stored in a secure system partition /system/app or /system/priv-app. These files are part of the firmware and take up space in a partition that is not displayed as free user memory.
Deleting or modifying files in these directories is only possible if you have Root rights. Normal deleting through settings only hides the application or disables its updates, but the installation package itself stays in place, taking up space in the system partition, and this is done to allow for quick restoration of factory state.
| Location. | Type of application | Access. | Risk of removal |
|---|---|---|---|
| /system/app | System (calculator, clock) | Only the Root. | High (the firmware can fly off) |
| /system/priv-app | Critical (phone, contacts) | Only the Root. | Critical (phone not switched on) |
| /data/app | Customized (from Play Market) | Limited. | Low (only data loss) |
| /data/data | Data and settings | Only the Root. | Medium (setting reset) |
When flashing a device, the /system partition is often formatted, so storing personal data there is pointless. The system partition has a fixed size, which is determined when the firmware is built by Xiaomi developers.
💡
System applications take up space in a hidden partition that does not affect the space available to the user for photos and music, but is critical for the OS to work.
Using ADB to manage application files
For advanced users who want to gain full control of the file system without obtaining Root rights, Android Debug Bridge (ADB) is an indispensable tool. This tool allows you to execute commands from a computer, having access to hidden directories that are closed to mobile applications.
With help. ADB You can (list) all packets installed and their paths. The pm list packages will show you a list of all packets, and the pm path will show you the exact path to the packet. APK-It's the most reliable way to find where a particular application is hiding.
adb shell pm path com.xiaomi.health
package:/data/app/~~xQ8...==/com.xiaomi.health-.../base.apkOnce you get the path, you can copy the file to your computer with the adb pull command. This allows you to create full backups of installed versions of programs before you upgrade. If the new version is unstable, you can easily roll back.
- 💻 Universality – works on all Xiaomi models with debugging enabled USB.
- 🔒 Security – does not require unlocking the bootloader or Root rights.
- ⚡ Speed – transfer of files through USB 3.0 is faster than Wi-Fi.
Don’t forget to turn on the developer mode and activate USB debugging in the MIUI settings. Without this, the computer will not be able to establish a connection to the phone’s file system. The HyperOS interface also requires confirmation of the connection on the smartphone screen.
Cleaning up garbage and optimizing storage
Knowing where apps are stored can effectively fight for free space. Standard cleaning through the Settings menu → Memory often leaves a deep cache. For deep cleaning, it is recommended to use the built-in Security app from Xiaomi, which analyzes large files and duplicates.
However, the most effective method is to manually analyze the Download and Android/obb folder. Often users forget about downloaded installers or abandoned games that take up gigabytes. Deleting the game folder from obb frees up space instantly, unlike the standard deletion, which can last a long time.
⚠️ Note: When cleaning folders manually, never delete files with the.xml or.db extension unless you are sure of their purpose.
Check the installed list regularly. MIUI has a Cleanup feature that highlights rarely used programs, and removing these apps is the best way to prevent the accumulation of digital garbage in the future.
💡
Use the "Duplicates" function in the Files app to find copies APK-files that may have been saved after the application update.
