How to transfer data to a memory card in Xiaomi smartphones: the complete guide

Transferring data to a memory card in Xiaomi smartphones is a challenge that most users face. The device’s internal memory is quickly filled with photos, videos and apps, and the device’s internal memory is filled with a lot of data. SD-But not everyone knows how to do the transfer correctly so that they don't lose data or run into errors. In this article, we'll look at all the ways, from standard functions. MIUI to hidden opportunities that are not written in the official instructions.

Xiaomi’s smartphone features flexibility in external storage. Depending on the model and version of MIUI (12 to 14), there are different options available: transfer applications, auto-save media to a map, and manually copy through the file manager. But there are nuances: not all applications support portability, and some models (such as the Redmi Note 12 Pro+ or POCO X5 Pro) require pre-configuring the formatting of the card as internal storage. We will discuss each case in detail.

It is important to understand that misconduct can lead to data loss or even phone malfunctions, such as removing a memory card while transferring files can damage the file system, making it unreadable, so be sure to read our recommendations and warnings before starting the procedure.

Preparation of a memory card: selection and formatting

Before you move data, you need to prepare the card correctly. Xiaomi smartphones support microSD up to 1 TB (depending on the model), but not all cards are equally good. The best choice is A2 or UHS-I U3 cards, which provide high read/write speeds. Cheap unlabeled cards can slow down the phone, especially when porting applications.

Before you use it, you need to format it. You can do it right on your smartphone.

1. Insert the card into the slot (in most Xiaomi models it is combined with a tray for the game). SIM-map).
2. Go to Settings → Storage → Memory Map.
3. Click Format and select the file system: FAT32 (for cards up to 32 GB) or exFAT (for cards over 32 GB).
4. Confirm the action. Attention: formatting will remove all data from the map!

If you plan to use the card as an internal storage (for transferring applications), select Use as internal memory in the settings. Note that after that the card can not be removed without losing data - it will become part of the system. This mode is not supported by all models (for example, Redmi 10A does not have one).

⚠️ Note: Formatting a card as internal storage can slow down your phone if the card is slow. A2 higher.

2. transfer of files (photos, videos, documents) to a memory card

The easiest way to free up internal memory is to transfer media files, and in MIUI, you can do this in a number of ways:

Method 1: Through a File Manager

Built-in Files (or Mi File Manager) allows you to quickly copy data:

1. Open the Files app.
2. Go to the Internal Storage section and select a folder (e.g. DCIM for a photo).
3. Press and hold the files to highlight, then tap More → Copy.
4. Return to the root directory, select the Memory Card and paste the files (Insert).

Method 2: Automatically save to the map

To ensure that new photos and videos are immediately saved to the SD-map:

1. Open the camera. → Settings (cogs).
2. Find the Warehouse item and select the Memory Map.
3. Confirm the change. All new images will now be saved to SD.

To transfer existing photos and videos, you can use the function of Storage Optimization in the Gallery application:

• 📁 Open the gallery. → Albums. → Settings (three points).
• 🔄 Choose Storage Optimization → Move it to the memory card.
• ✅ Confirm the transfer. The process may take a few minutes.

💡

If photos are not displayed in the gallery after transferring, restart your phone or update the media base through the Files app (Settings → Update media files).

3. Transfer of applications to a memory card

Not all applications can be transferred to SD-map, but for those that support this function, the algorithm is as follows:

1. Go to Settings → Applications → Application Management.
2. Select the app you want (like Facebook or Spotify).
3. Click Warehouse → Change → Memory Map.
4. Wait for the transfer to be completed (may take up to a few minutes).

If the Change button is inactive, the application does not support portability, as is the case for most system utilities and some games (e.g. PUBG Mobile or Genshin Impact).

⚠️ Note: Transferring applications to a memory card can cause them to work unstable, especially if the card is slow.In some cases, applications may accidentally close or not update.

4. Data transfer via PC (alternative method)

If transferring directly over the phone is difficult, you can use a computer, which is suitable for large files (for example, movies or archives).

You'll need:

• 🖥️ Computer with Windows/macOS;
• 🔌 USB-cable (preferably original from Xiaomi);
• 💾 Cardholder (if the phone does not recognize the card when connecting).

Instructions:

1. Connect your phone to your PC in File Transfer (MTP) mode (select this mode in the notification curtain).
2. Open this computer (Windows) or Finder (macOS) – there will be two drives: internal memory and card.
3. Copy the desired files from internal memory to the card through the explorer.
4. Once completed, safely remove the device.

If the phone is not displayed on the PC:

• 🔄 Try another one. USB-cable (not all support data transmission).
• 🔧 Install Mi drivers PC Suite from the official Xiaomi website.
• 📱 Turn on Debugging. USB In Settings → The phone. → Version. MIUI (Press 7 times, then return to the Additional Settings → For developers).

5. Solving common errors in transfer

When working with memory cards, Xiaomi users often face typical problems, and let’s analyze the most common and ways to fix them.

Error: "Memory card damaged"

If the phone is giving you this message:

• 🛠️ Format the card via phone (Settings) → Warehouse → Memory map → Format).
• 💻 If formatting doesn’t help, try doing it via PC (right-click on disk). → Format, file system FAT32 exFAT).
• 🚫 If the error is repeated, the card is faulty, replace it.

Mistake: "Not enough space on the map"

Even if the map is empty, the system can show this error.

• 📏 The map is formatted in FAT32, which does not support files larger than 4 GB. Solution: reformat to exFAT.
• 🗑️ There are hidden system files on the map. Solution: connect the card to your PC and delete unnecessary files manually.

Error: "The application is not transferred to the map"

If the transfer button is inactive:

• 📱 Check if the app supports portability (many games and system utilities – no).
• 🔄 Try to clear the app cache (Settings) → Annexes → [name] → Clear the cache).
• 🛠️ If the card is formatted as internal storage, some applications may still not be portable.

💡

If the memory card stopped being determined after the MIUI update, try resetting the storage settings: Settings → System → Resetting → Reset the storage settings.

6. Optimization of work with memory card on Xiaomi

To make the memory card work quickly and without failure, follow these tips:

• 🔋 Regularly (every 1-2 months) format the card via the phone – this clears fragmented data.
• 📉 Don’t fill 100% of the card: leave at least 10% free space for stable work.
• 🔄 Use a card reader for large files (for example, movies in the 4K), so as not to load the phone.
• 🛡️ Install an antivirus (such as Avast or Dr.Web) and scan the map for viruses periodically.

To speed up the work of the card as an internal storage:

1. Go to Settings → Storage → Memory Map.
2. Select Data Transfer and move as many files as possible to the map.
3. Enable the option to Save new files to the memory card (if available).

If you often shoot high-resolution video (4K@60fps), we recommend using cards at a write rate of at least 90MB/s (for example, SanDisk Extreme Pro).

7 How to safely remove the memory card

Incorrectly extracting the card can lead to data loss or file system damage.

1. Close all applications that work with the card (gallery, player, file manager).
2. Go to Settings → Storage → Memory Map.
3. Click Extract (or Safely Extract in some versions of MIUI).
4. Wait for notifications to the Memory Card can be retrieved.
5. Carefully take the card out of the slot.

⚠️ Note: If you extract the card without safely turning it off and the phone can't see it now, don't try to insert it back right away. Connect the card to your PC via a card reader and check for errors using the chkdsk (Windows) utility or Disk Utility (macOS) utility).

If you use the card as an internal storage device, you can't retrieve it without resetting the phone to the factory settings.

• First, transfer all important data back to internal memory or to the cloud (Mi Cloud, Google Drive).
• Go to Settings → System → Resetting → Delete all data.
• After resetting the card can be removed, but all data on it will be deleted.

8.Alternative Memory Freeing Methods

If transferring to a memory card does not solve the problem of space shortage, consider other options:

• 🌥️ Cloud storage: Mi Cloud (5 GB free), Google Photos (unlimited storage of compressed photos), Yandex Drive (10 GB).
• 🧹 Cache cleanup: Settings → Warehouse → Clear (delete temporary files).
• 🗑️ Remove duplicates: Use applications like Files by Google or CCleaner.
• 🔄 Reset to factory settings: an extreme method if the phone is heavily clogged with unnecessary files.

To automate memory cleaning, MIUI has a Smart Cleaning function:

1. Go to Settings → Storage → Smart Cleaning.
2. Turn on the option and set up a schedule (like cleaning every Monday).
3. Select file types to delete (cache, temporary files, unused APKs).

If you frequently install and remove applications, we recommend using APK Extractor to create backup copies APK-So you can quickly restore the application without re-downloading it.

💡

For Xiaomi models with OTG support (such as the Redmi Note 11 Pro), you can connect an external SSD or flash drive via an adapter, which allows you to carry large amounts of data without using a memory card.
