How to transfer files to a memory card in Xiaomi smartphones: the full guide

Xiaomi smartphones based on MIUI Often face the problem of lack of internal memory, especially if you actively shoot videos in the video. 4K, You can install heavy games or store large collections of music. A microSD card might be the perfect solution, but by default, the system stores almost all files in internal storage. SD-map – from photos and videos to apps and cache, and consider the typical errors and limitations MIUI.

It’s important to understand that the memory card features depend on the MIUI version (12, 13 or 14) and the smartphone model. For example, the flagships of the Xiaomi 13 or Redmi Note 12 series support Adoptable Storage, and budget models like the Poco M5 only classic FAT32/exFAT formatting. We will discuss both options in detail, and also explain how to circumvent the manufacturer’s restrictions without root rights.

Preparation of a memory card: format selection and compatibility check

Before you set up file saving, you need to properly prepare the card itself. Xiaomi officially supports microSD up to 2 TB, but in practice, cards up to 512 GB speed class A2 or UHS-I U3 are more stable. Using slow cards (for example, Class 4) will lead to lags when recording videos or installing applications.

Modern Xiaomi smartphones offer two formatting options:

• 📁 Portable storage (FAT32/exFAT) — The card works like a removable drive. Files can be transferred manually, but applications are installed in internal memory by default.
• 🔄 Internal Storage – the card becomes part of the system (similar to the partition). /data). Allows you to install applications directly on SD, But after the map is extracted, the data will become unavailable.

⚠️ Note: Adoptable Storage formatting erases all data on the map and encrypts it. Once the card is removed from your smartphone, it will be impossible to read files on another device without full formatting.

To check the compatibility of the card:

1. Insert the card into the slot (in models with a hybrid tray, for example, the Redmi Note 11, you will have to choose the second SIM or microSD).
2. Go to Settings → Storage → Memory Map.
3. Click Format as internal (if the option is active) or select Portable Storage.

2. Configure the saving of photos and videos on the memory card

By default, Xiaomi's camera saves the pictures to internal memory, even if the card is inserted.

For MIUI 14 (relevant to Xiaomi 13/12, Redmi Note 12):

1. Open the Camera app.
2. Touch the gears. ⚙️ top-right.
3. Select Camera Settings → Save Place → Memory Map.
4. Confirm the choice (the system may request permission to access the storage).

For MIUI 12/13 (older models like Redmi 9 or Poco X3):

1. Launch the camera. → Settings (three points in the corner).
2. Go to the Supplementary → Preservation site.
3. Choose. SD-If the option is inactive, the card is not formatted as internal storage.

⚠️ Note: When recording video in 4K@60fps or 8K The system can ignore settings and save files to internal memory due to card speed limits. SD: for 4K need UHS-I U3 or A2.

3. Transfer of applications to a memory card: limitations and workarounds

MIUI has a built-in SD portability feature, but it doesn't work with all programs, such as system applications (like Google Play Services) or secure games (like Genshin Impact) can't be migrated.

Instructions for MIUI 12-14:

1. Open Settings → Applications → Application Management.
2. Select the application you want (such as Telegram or Spotify).
3. Click Warehouse → Change → Memory Map.
4. Wait until the transfer is completed (may take a few minutes).

Critical limitation: even after the transfer, some data (cache, updates) will remain in internal memory, this applies to all Xiaomi smartphones, except models with Adoptable Storage support (for example, Xiaomi Mi A2 on pure Android).

Alternative methods:

• 📲 Using a file manager: manually move application folders (e.g, Android/obb for games SD Directed by the Conductor or Total Commander.
• 🔧 Forced transfer through ADB (PC requires: connect the smartphone to USB, activate the debugging. USB and execute the command: adb shell pm set-install-location 2 This will force the system to install new applications on the site. SD The downside is that not all apps will work correctly.

4. Automatically save downloads and files on SD

Browsers, messengers and file sharing devices (such as Telegram or Xender) save files to internal memory by default.

For Xiaomi's Browser:

1. Open the browser, tap. ⋮ → Settings.
2. Select Downloads → Download folder → Memory Map.
3. Create a folder (like Downloads) or select an existing one.

For Telegram:

1. Go to Settings → Data and Storage → Download folder.
2. Click Change and choose the path to SD (for example, /storage/XXXX-XXXX/DCIM/Telegram).

For Xender or ShareIt:

• 📎 In the application settings, find the File Saving or Download folder section.
• 📂 Specify the path to the memory card (for example, /storage/XXXX-XXXX/Download/Xender).

💡

If the application does not allow you to select SD in the settings, create a folder on the map with the name of the program (for example, WhatsApp) and manually move files there via Explorer or FX File Explorer.

5. Solving typical errors when working with a memory card

Xiaomi users often face problems like “Memory card not found", "SD-The card is damaged" or "not enough rights to record:

Error 1: "Memory card is not supported"

• 🔌 Check the physical connection: Remove and paste the card again (in hybrid slots, make sure that the second one is not inserted). SIM).
• 📏 Make sure the card doesn’t exceed the maximum supported volume (e.g. Redmi 8 officially works with cards up to 256GB).
• 🔄 Format the map in FAT32 on PC (through SD Formatter and reconnect.

Mistake 2: “Not enough space on the map” when memory is free

• 🗑️ Delete hidden files (such as.thumbnails or.trashes folders) through Explorer with hidden files enabled.
• 🔄 Reformat the card to exFAT (supports files) >4GB and works better with larger volumes).
• 📱 Reboot your smartphone – sometimes MIUI miscalculating the vacant space.

Error 3: Apps are not installed on SD

• 🔧 Check that the card is formatted as an Internal Storage (see Section 1).
• 📦 Install AppMgr III from Google Play – the application allows you to force transfer APK on SD rootless.
• 🔄 Reset the application settings: Settings → Annexes → ⋮ → Reset the settings.

⚠️ Note: If the Suddenly memory card is read-only, don't format it right away! Try connecting it to a PC and checking for viruses (for example, through Dr.Web CureIt.

6. Optimization of performance when using SD-map

Memory cards are slower than the built-in UFS or eMMC, so when you use SD actively, you can get lags. Here's how to minimize the brakes:

For photo and video:

• 📸 Shoot in Full. HD instead 4K, class-card U1 — It'll reduce the load on the record.
• 🔄 Turn it off. HDR or AI-camera in camera settings – processing images requires fast memory.
• 📁 Regularly transfer files from the map to the PC or cloud (such as Google Photos) to free up space.

For applications:

• 🎮 Don't put it on. SD heavy games (such as Call of Duty Mobile) PUBG) — They will slow down because of the slow reading speed.
• 📱 Use the Cache Cleanup function in Settings → Storage to avoid fragmentation of the map.
• 🔋 Turn off Adaptive Brightness and Autosynchronization in the background – this will reduce the number of recording operations.

For the durability of the map:

• 🔄 Avoid frequent overwriting of small files (for example, messenger cache) – this reduces the life of flash memory.
• 📉 Don’t fill up more than 80% of the card, which can impair performance.
• 🔌 Remove the card only through Secure Retrieval in the Notification Curtain to avoid damaging the file system.

💡

Class A2 memory cards (such as Samsung EVO Plus or SanDisk Extreme) are optimized for smartphones and run 30-40% faster than conventional U1s. For Xiaomi, this is critical when recording videos or running games with SD.

7.Alternative ways to expand memory without SD-map

If your Xiaomi smartphone doesn’t support memory cards (such as the Xiaomi 13 Ultra or Black Shark 5), consider other options:

Cloud storage:

• ☁️ Google Photos – Automatic upload of photos and videos in original quality (up to 15 GB free).
• ☁️ Mi Cloud – 5 GB from Xiaomi, integrated into the MIUI (settings in the Xiaomi Account → Mi Cloud).
• ☁️ Yandex Drive or Mega – up to 20 GB free, there is automatic folder synchronization.

USB-accumulator (OTG):

• 🔌 Connect the flash drive through USB-C/OTG-Adapter (supported by all modern Xiaomi).
• 📁 Use Explorer to transfer files or set up the camera to save USB-storage device (in some firmware).

Network Storage (NAS):

• 🌐 Set up access to the home NAS (for example, Synology or WD My Cloud through FX File Explorer or Solid Explorer.
• 📡 Use it. FTP-server on PC (via FileZilla) for remote access to files.

Optimization of internal memory:

• 🧹 Remove duplicate photos via Google Files or CCleaner.
• 🎵 Transfer music to streaming services (Spotify, Yandex Music) instead of storing locally.
• 📦 Archive rarely used files in ZIP/RAR (save up 30% place).
