Owners of the Xiaomi Redmi 5 smartphone often face a lack of built-in storage, especially in versions with a storage capacity of 16 or 32 GB. After installing the necessary social networks, messengers and a couple of games, the free space ends, which leads to a decrease in the performance of the device. The system begins to work slower, and notifications about the memory shortage appear at the most inopportune moment.
Fortunately, MIUI architecture allows you to manage files and data flexibly, using the capabilities of extensions. Moving applications to an external drive is an effective way to free up precious gigabytes of internal module. In this guide, we will break down all available methods, from standard settings to advanced solutions.
It is important to understand that this process is not always automatic, as Android’s security policy limits direct access to external media, but there are proven ways to get around these restrictions without losing the warranty and stability of the gadget.
Preparation of a memory card and smartphone
Before you start moving data, you need to make sure that the drive used is compatible and serviceable. Redmi 5 supports microSD cards up to 128 GB, although many users successfully use 256 GB. It is important that the card has a high speed class, otherwise launching applications will be a long and painful process.
It is recommended to choose a drive labeled Class 10 or UHS-I. Slow cards can cause interface freezes and errors when working with heavy programs. If you use an old drive that previously worked on other devices, it is better to pre-format it.
To format, go to the Settings menu, then select Advanced Settings and find the Memory section. This menu will display information about the built-in storage and external map.
- 🔍 Insert the card into the slot before the characteristic click and wait for the system notification.
- 🗑️ Click the “Clean” or “Format” button in the Memory Management Menu.
- ⚙️ Choose the use case as Portable Storage for maximum compatibility.
- 📱 Make sure the system correctly determines the storage volume and status.
⚠️ Note: Formatting will completely remove all files from the memory card. be sure to save photos, documents and music to your computer or cloud storage before starting the procedure.
Once formatted successfully, the system will create the required folder structure, and now the device is ready to receive data from internal memory, and do not remove the card while the smartphone is running, so as not to damage the file system.
Standard method of transfer through MIUI settings
The MIUI shell provides basic functionality for managing applications, but it has its limitations: Not all programs allow their data to be moved to an external medium by standard means, because application developers themselves specify in the code where their product can be installed.
To try to migrate, open Settings and go to the Apps section. Next, select All Apps and find the desired program in the list. If the developer has authorized the move, the Move to button. SD-The map will be active.
Otherwise, the button will be inactive or absent, which is normal for many modern applications, such as WhatsApp, Telegram or banking clients, which require high data read speeds provided only by internal memory.
If the standard method didn't work, don't despair. There are alternative ways to solve the problem that require more in-depth intervention, but produce the desired result.
Use of Adoptable Storage
One of the most effective technologies in the Android ecosystem is Adoptable Storage, which allows treats to be an external memory card as part of internal storage, and for the user, it looks like the smartphone’s built-in memory has magically increased.
On Xiaomi Redmi 5, this option is often hidden by the firmware developers, but it can be activated. When this feature is enabled, the card is formatted into a special file system, and ordinary file managers on a PC will no longer see it without a special adapter and software.
Activation often requires you to enter special commands through ADB debugging or root permissions. If your smartphone is running global firmware, the chance of finding this option on the menu is higher, and in Chinese versions of MIUI it is most often blocked.
| Parameter | Portable storage | Internal storage (Adoptable) |
|---|---|---|
| Access to PC | Aye (via cable) | No (unmounting required) |
| Portability of applications | Partial or impossible | Full and automatic |
| Security | Data open. | Data encrypted by binding to the device |
| Speed of operation | Depends on the card. | High (when using fast cards) |
The main advantage of this approach is that it automatically installs new programs on a map, and it decides where to place the data, optimizing the space, but retrieving such a map without first unmounting it in the settings will lead to errors in the system.
💡
Use memory cards only from proven brands (Samsung, SanDisk, Kingston). Cheap Chinese counterparts often have a real volume of 2-3 times less than claimed, which will lead to data loss.
Transfer of media files and messenger cache
Even if you can’t migrate the app itself, you can almost always move its “heavy” content, with messengers like Telegram and Viber tending to accumulate gigabytes of cache, photos and videos that take up the lion’s share of memory.
To transfer, use the built-in File Manager Explorer. Find the Android folder, then the media or data. This is where most programs store data. You can move the folders from the photos and videos to the map, leaving the system files in place.
The app settings themselves often have a save path, go to Telegram settings, select Data and memory, and specify the path to the memory card, and you have similar settings in cameras, voice recorders, and navigators.
- 📂 Open the “Conductor” and find the folder. DCIM (camera).
- ✂️ Select files and select “Move” to the root of the memory card.
- 📁 Create a new folder on the map for orderly data storage.
- ✅ Check that files have been opened from a new storage location.
This approach frees up internal memory without the risk of app disruption, and the system continues to see paths to files if you use symbolic links, or you simply manually specify new paths in your software settings.
⚠️ Warning: Do not move files with the extension.obb manually without understanding the structure. These are game data files, and if you move the game incorrectly, the game will stop running and require a re-download of data.
Advanced Opportunities Through ADB and Root Rights
For users who are ready for more complex manipulations, there are tools like ADB (Android Debug Bridge), which allows you to force the system to change the configuration, allowing you to transfer any application, which requires a computer and a USB cable.
First, activate the developer mode. Go to Settings → About Phone and quickly click on the MIUI build number seven times. Once you have become a developer, go back to the advanced settings menu.
Turn on USB debugging. Connect your smartphone to your PC and start the command line with administrator permissions. Enter a command to change the global variable:
adb shell pm setInstallLocation 2A value of 2 indicates the system to use external storage. A value of 0 returns automatic selection, and 1 This method does not work on all Android versions and MIUI firmware, but on Redmi 5 with Android 7 or 8 often gives the result.
Risks of using ADB
The alternative is to get Root rights and use specialized utilities like Link2SD. This application creates symbolic links, tricking the system into thinking that the applications are in internal memory, even though they are physically located on the map.
Optimization and maintenance after the transfer
Once you have moved applications and files, it is important to maintain the system. Fragmentation of data on the memory card can reduce the speed of reading over time. Periodically check the state of the drive through the settings menu.
It is recommended to back up important data from card to computer every few months. External drives are less reliable than the built-in flash memory of a smartphone, and are more prone to failures when voltage surges or software errors.
Watch the temperature of the device. Active work with the memory card, especially when writing large amounts of data, can cause additional heating of the processor and memory controller. If the smartphone starts to warm, take a break from work.
☑️ Checklist of memory optimization
Use memory cleaning widgets with caution. Aggressive accelerators often drain the battery, constantly unloading the necessary processes from the RAM, which makes the Redmi 5 processor work harder.
💡
Regular cleaning of cache and transfer of media content more effectively affect the speed of the smartphone than the constant reinstallation of applications.
