How to save files to a memory card in Xiaomi phones: all the ways and nuances

Xiaomi smartphones support memory expansion with microSD cards, but not all users know how to use this space effectively. The device’s internal memory is quickly filled with photos, videos and applications, and transferring data to an external drive can be difficult. In this article, we will discuss all the ways to save files to the memory card, including setting up by default, manual movement and solving typical errors.

Features of Xiaomi phones (especially models on the phone) MIUI) — Flexible storage management, but with some limitations, for example, not all applications can be migrated to the storage space. SD-card, and for the correct operation of the drive it is often required to format in FAT32 We will explain in detail how to avoid data loss and optimize the use of external memory.

Preparation of a memory card: selection and formatting

Before saving files to a Xiaomi memory card, it needs to be properly prepared. Not all microSDs are equally compatible with the brand's devices. The best choice is A1/A2 or UHS-I/UHS-II cards with write speeds from 30 MB / s. For models with support for Adoptable Storage (for example, Redmi Note 10 Pro), drives with a capacity of up to 1 TB will suit, but check the limitations of your firmware.

Formatting is a must if the card is new or has been used on another device. In MIUI, this is done via the Settings menu → Memory → SD card → Format. Important: the process will delete all data! For maximum compatibility, choose the exFAT file system (for cards >64 GB) or FAT32 (up to 32 GB).

• 📌 Classes of memory cards: A1 — application, U3 — video 4K, V30 — professionally.
• ⚠️ Incompatible formats: NTFS Not supported by most Xiaomi smartphones without root rights.
• 🔄 Backup before formatting: Copy data to PC or cloud as recovery after cleaning is impossible.

⚠️ Note: SanDisk Ultra and Samsung Maps EVO Plus is most often non-failing, but cheap no-name drives can cause write errors. H2testw beforehand.

• 🎵 Music and documents: In apps like Mi Music or WPS Office Select External Storage in Saving Settings.

For system files (e.g. screenshots), the path changes via Settings → Memory → Default location. Note that some apps (e.g. WhatsApp) require manual media transfer even after changing settings.

If files are already stored in internal memory, you can manually transfer them. Use the built-in File Manager:

1. Open the Conductor. → Internal memory.
2. Select files/folders (long press).
3. Click Move → SD Card → Select folder.
4. For large files (>1 GB), the process can take several minutes.

An alternative way is to connect your phone to your PC via USB (file transfer mode) and drag the data to the memory card folder. Note: some system files (for example, from the Android folder) cannot be moved without root rights.

4. Transfer applications to a memory card

Not all applications in Xiaomi can be moved to SD-This feature depends on the developer support and the Android version to check portability:

1. Open Settings → Applications → Application Management.

Some games (such as PUBG Mobile) block the transfer due to cheat protection.

⚠️ Note: Adoptable Storage is only available on pure Android devices (e.g., on internal and external storage, POCO F1 or Mi A3). V MIUI It's disabled by default. Forced activation through ADB may cause disruption!
