Xiaomi smartphone owners often face a shortage of internal memory, especially if the device is used to install heavy games and applications. Internal storage quickly fills up, which leads to a slowdown in the system and the inability to install new programs. One solution to the problem is to use the external USB-storage device and, in some cases, the applications themselves.
However, the transfer process is not always obvious and direct, as users would like. the interface MIUI and HyperOS have their own features that limit the direct migration of executable files to external media without special settings. Understanding these limitations and knowing the right configuration methods allows you to effectively expand the capabilities of your smartphone.
In this article, we will discuss how to properly prepare the flash drive, what are the ways to transfer data and why some applications categorically refuse to move, you will learn about the hidden features of the system that can help in solving the problem, as well as the risks associated with using external drives as system partitions.
Why Xiaomi is limiting application portability
Many users are surprised to find that the standard function of transferring applications to a memory card or flash drive in their device is absent or inactive. This is due to Xiaomi’s policy and the peculiarities of optimizing the Android operating system (UFS eMMCs are significantly higher than most external USB-If you move a heavy application to a slow drive, it can cause critical delays, interface freezes and unstable work of the gadget.
There is also a data security problem: applications installed on an external medium can be accessed by other devices when the flash drive is connected to a computer, which creates a vulnerability. MIUI by default, block the installation APK-files directly to an external disk, requiring their placement in internal memory to ensure the integrity of files and the correct operation of drivers.
⚠️ Warning: Forced transfer of system applications or mission-critical services to an external drive may result in a cyclical device restart (bootloop) or complete system failure.
However, for media files, documents and some user programs, portability is possible and even recommended, freeing up precious space for cache and temporary files that are necessary for processor speed, and distinguishing between “application port” and “application data port” is important, as the mechanisms of their work are different.
Preparation USB-storage
Xiaomi smartphones support connection via USB Type-C or Micro-USB port (in older models), but the storage file system must be compatible with Android. Most devices read FAT32 format without problems, however, exFAT or NTFS file system is required to store files larger than 4 GB.
To format the flash drive directly on the phone, perform the following steps:
- 🔌 Connect. USB-storage OTG-smartphone-connector.
- 📱 Go to the Settings menu → The phone. → Storage (or Advanced Settings).
- 💾 Click on the name of the connected USB-Devices and select the option "Format".
During the formatting process, all data on the flash drive will be destroyed, so back up important files on your computer beforehand. Once the procedure is complete, the system will suggest using the drive as "Portable Storage" or, in rare cases (depending on the Android version), as "Internal Storage." For our purpose, the first option is suitable, since it provides compatibility with other devices.
☑️ Preparation of the flash drive
Use of the “Internal Storage” function
In older versions of the shell MIUI And on pure Android, there was Adoptable Storage, which allowed you to combine your internal memory and flash drive into a single space. If your smartphone supports this option, the system will offer formatting. USB-It's a drive and it's encrypted, and then you can move it to a flash drive through the standard application management menu.
However, in modern Xiaomi firmware, this feature is often hidden or completely removed by developers. If you don't see the sentence "Use as internal storage" when you connect the flash drive, then this option is software blocked. ADB-commands can lead to unstable operation, as the system algorithms are not optimized for constant writing to an external disk.
If the function is available, the process looks like this:
- Connect a quick flash drive (preferably USB 3.0 and higher).
- In the storage menu, select formatting as an internal drive.
- Wait for the process to be completed and restarted.
⚠️ Warning: Once the flash drive is formatted as internal storage, it will only work with that particular phone.
Why is Xiaomi hiding this feature?
Application Data Transfer and Multimedia
Since direct transfer of executable files (.apk) is often blocked, the most effective method is to transfer application data (cache, downloaded files, offline maps). Many modern programs, such as navigators, messengers and video editors, allow you to choose the way to save files. This does not require root rights and is safe to guarantee the device.
Let’s look at how to change the way you save in popular apps:
- 🗺️ Yandex.Maps / Google Maps: Go to the application settings, find the "Storage of maps" section and indicate the path to the app USB-accumulator.
- 💬 Telegram / WhatsApp: In chat settings, select "Use" SD-Map or change the way media files are downloaded in the file manager.
- 🎵 Spotify / Yandex.Music: In the quality and storage settings, specify an external drive for caching tracks.
To transfer existing files, you can use built-in Explorer. Select folders with heavy content (for example, DCIM, Download, Documents), click Move, and select the root directory of your USB drive. This will free up gigabytes of space that the system will consider free to install new updates.
💡
Use a file manager called Mi Explorer or a third-party equivalent like Total Commander to packet-transfer folders, which is faster and more reliable than dragging files one by one through a computer.
Comparison of methods of memory expansion
There are pros and cons to solving memory problems, and the best method depends on your device model and the type of storage you use, and here is a table to help you decide on strategi.
| Method | Security | Efficiency | Difficulty |
|---|---|---|---|
| Transfer of media files | Tall. | Medium | Low. |
| Set-up of paths in applications | Tall. | Tall. | Low. |
| Internal storage function | Medium | Maximum | Medium |
| Root rights and scripts | Low. | Maximum | Tall. |
As you can see from the table, the safest and most sensible approach is to combine the transfer of media files and configure the paths in the applications themselves. Using root rights gives you complete control, but requires deep technical knowledge and carries the risk of system failure.
💡
The optimal strategy is not to transfer the applications themselves, but to transfer their “heavy” content (cache, databases, media) to an external medium.
Possible problems and solutions
Users may encounter various errors when using external memory "USB-drive damaged" or "Formatting required" may indicate file system incompatibility or port power shortage USB. Try to use quality OTG-additional power cable, if the flash drive is energy intensive.
Another common problem is that applications stop working after the flash drive is removed, which is normal because the executable code or the required libraries are on an external medium. To avoid data loss, always use the Safe Retrieval feature in the notification menu before turning off the device.
⚠️ Note: Do not remove the flash drive while writing data or running applications using external memory.This can lead to corruption of the file system and loss of stored progress in games.
If the phone doesn't see the flash drive at all, check the format. Xiaomi works best with FAT32 and exFAT. The NTFS format may require installing additional drivers or plugins for the file manager, such as "Microsoft exFAT/NTFS for USB by JellyFish."
