SD-map.
Why Xiaomi doesn’t save files SD-default-card?
The manufacturer is setting up MIUI to prioritize internal memory, for a few reasons:
- 🔹 Speed of work: Internal memory UFS 2.2/3.1 (in new models, working in 5–10 It is faster than the fastest microSD. UHS-II. It's critical for apps and cache.
- 🔹 Security: Data on SD-It is easier to steal or damage the card (for example, when retrieved during recording). MIUI Blocks the storage of certain types of files (such as screenshots) to external media.

But it's not always convenient for the user. For example, if you're downloading movies in 4K or big archives, the internal memory on the Redmi Note 12 (64GB) will fill up in a few days. Fortunately, there are ways to reconfigure the system.
⚠️ Note: Not all applications support saving on SD-For example, WhatsApp and Telegram, by default, store media files only in internal memory, and they will require additional settings (see section 5).

Method 3: Transfer applications and their data to SD-map
If the internal memory is filled not with files, but with the applications themselves, you can transfer them to the computer. SD-But the map. MIUI This greatly limits the function:
- ✅ What to transfer: Only a part of the applications (usually games and lightweight utilities) System applications and instant messengers can not be transferred.
- ❌ What can not be transferred: widget apps (for example, Weather), Google services, banking applications.
For convenience, create on SD-folder map by category:

adb shell settings put global download_manager_max_bytes_over_mobile 2147483648
adb shell settings put global download_manager_recommended_max_bytes_over_mobile 2147483648🛠️ Root-right methods
If you have root, you can:
- 🔹 Change the access rights to folders SD-mapping through Root Explorer.
- 🔹 Reassign Storage Paths with Xposed Framework (HandleExternalStorage Module).
- 🔹 Use Magisk for mounting SD-Cards as internal memory (risky!).
