Owners of Xiaomi, Redmi and Poco smartphones often face the need to optimize internal space or switch to a new device. In the Android ecosystem, and especially in the MIUI shell, application file management has its own unique features.Moving an application can mean both changing the location of its installation and migrating data between devices.
Modern versions of the operating system have strict security restrictions that prevent you from simply copying an executable file anywhere, but there are proven methods to solve these problems. In this article, we will discuss how to safely move data, use external drives and not lose progress in games when changing gadgets.
Understanding the structure of the Android file system is the first step to memory management. Standard tools often hide complex settings but provide basic user experience. Starting with Android 11, direct access to the Android/data folder is limited to third-party file managers without special permissions.
Internal portability and desktop organization
The simplest scenario that many users are interested in is moving the shortcut on the desktop or changing the order of items in the menu. In the MIUI shell, this is done by drag-and-drop, you can create folders, group software into categories and bring widgets to individual screens.
If you're moving the program body inside the device's memory, it's more complicated. It automatically allocates resources, and you can't manually change the path to executable files (.apk) in the system partition without root rights.
To clean up the space and optimize your work, use built-in tools. Go to Settings → Applications → All applications. Select the right list item. Here, actions to clean up the data and cache are available, which often frees up more space than trying to transfer.
💡
Use the Cleanup mode in Xiaomi’s Security app to automatically search for heavy and rarely used apps that take up space.
Organization of the workspace is important for speed. When there are too many widgets and live wallpaper on the home screen, the system can run slower. Try to keep only those programs that you use daily active.
Use of the SD-maps as external storage
Many Xiaomi models are equipped with a microSD card slot. Users often want to install heavy games or instant messengers there to free up internal memory. MIUI function “Move to the SD-Map for system applications is often missing or hidden.
This is done for stability reasons: if the memory card fails or is retrieved, the application will cease to function, which can lead to system errors. However, some programs, especially games with a large amount of data, allow you to manually transfer some files (cache, resources) to an external medium.
- 📁 Go to the settings of a particular application and find the item "Storage».
- 💾 If the function is available, the “Change” button will allow you to select SD-map.
- 📂 Games often require transferring cache files (obb folder) manually through the file manager.
- ⚙️ Use the "Advanced Memory" feature if it is available in your model for virtual zooming RAM.
⚠️ Note: Do not try to force system applications to SD-card with third-party root-rights software, which can lead to a "bootloop" (cyclical reboot) of the smartphone.
Use standard conductor to work with files on external media. The path to files usually looks like /storage/emulated/0/ for internal memory and /storage/sdcard1/ or external. When transferring game cache, it is important to keep the folder structure.

Transferring data to the new Xiaomi phone
When you buy a new Xiaomi or Poco smartphone, you have to migrate data, and the best tool for that is the built-in Mi Mover app, which lets you transfer contacts, messages, photos, music and, most importantly, installed apps along with their data.
It doesn't require an internet connection, because it creates a direct Wi-Fi connection between the devices, and it allows for a high transfer rate, and it's important that both devices have GPS and Bluetooth on for initial detection.
The algorithm is simple: install Mi Mover on both devices (the new ones already have it built into the Tools folder). On the old phone, select "I send"; on the new one, select "I accept." Scan. QR-code and select data categories for transfer.
☑️ Checklist before data migration
Some banking apps and secure messengers (such as WhatsApp) require a separate backup procedure. Mi Mouvre can transfer the application file itself, but to recover correspondence you need to make a backup inside the messenger itself via Google Drive or a local file.
| Type of data | Transfer method | nuance |
|---|---|---|
| Contacts and SMS | Synchronization with Google/Mi Mover | Automatic recovery when logging into your account |
| Photos and videos | Google Photo / Mi Cloud / PC | Requires a stable internet or cable |
| Annexes | Mi Mover | Passwords will have to be re-entered for security reasons. |
| Document files | Conductor/ShareMe | Better to transfer archives for speed |
Installation of applications from APK-file
Sometimes you need to transfer an installation file (APK) from a computer or other phone and install it manually, which is true for regions where some Google services are limited, or for installing modified versions of programs, and you need to copy the file to any folder on your smartphone.
When you first run the installer, MIUI will issue a security alert, which is standard virus protection, and you will need to allow installation from unknown sources for the specific application (browser or explorer) through which you run the file.
Click Settings in the window that appears and activate the Allow switch, and then you can go back and click Set, and the system will check the file for malicious code through Google Play Protect.
Be careful when downloading files from unverified sources, malware can steal bank card details or lock your device, always check the digital signature of the application if possible, or use antivirus scanners.
Working with memory sections and root rights
For advanced users, there is a possibility of deep modification of the system, which allows you to transfer any application, including system, to any partition of memory, using managers like Titanium Backup or Root Explorer.
However, on modern Xiaomi devices, unlocking the bootloader has become more difficult, requiring a wait of 7 days (sometimes longer) after submitting an application in the Mi Unlock app, and some banking applications and NFC services (payment by phone) stop working after unlocking.
If you do, make a full TWRP recovery. Any error in moving system files can make your phone unusable.
⚠️ Warning: Unlocking the bootloader and obtaining root rights will void the manufacturer's warranty. Official service centers may refuse free repairs.
Instead of completely rooting, it is often enough to use ADB (Android Debug Bridge) to remove or freeze unnecessary system software.This is safe and does not require unlocking the bootloader, but requires a connection to the computer.
Frequent problems and their solution
Users may experience errors during porting or installation, such as “App not installed” often resulting from version conflicts (trying to install an older version on top of a new one) or space shortages.
Another common problem is black screen or crashes after data transfer, which is solved by clearing the cache of a particular application or completely resetting the settings (Settings → Advanced → Resetting).
If the application stopped working after the MIUI update, try to remove the updates to the application itself or clear its data. Sometimes reinstall the problematic software helps. Don't ignore system updates, as they often contain compatibility patches.
💡
Regular updates to the operating system and applications are the best prevention of errors when working with memory and data transfer.
Understanding how your Xiaomi file system works will help you avoid many problems. Don’t be afraid to experiment with settings, but always have an up-to-date backup of important data at hand.
