How to transfer data from phone to memory card in Xiaomi Redmi 7A: all working methods

Xiaomi Redmi 7A is one of the most popular budget smartphones with support for microSD cards up to 256 GB. But even with this feature, many users face problems when trying to free up the internal memory of the device. Why does the system prevent you from moving applications? How to move photos and videos correctly so that they do not disappear after retrieving the card? And why some files persist in returning to internal memory?

In this article, we will discuss all the current ways to transfer data to Redmi. 7A — standard-function MIUI You will learn which files can be moved without risk, which are better left on the internal drive, and how to avoid typical errors when working with the computer. SD-We will pay special attention to the limitations of Android 9 Pie, which runs this smartphone.

1. Memory card preparation: formatting and file system selection

Before transferring data, you need to properly prepare the microSD. Xiaomi Redmi 7A supports cards up to 256 GB, but there are nuances with the file system:

• 🔹 FAT32 — It is compatible with all devices, but limits the size of a single file to 4 GB.
• 🔹 exFAT – removes the file size limit, but may not be readable on older computers or car radios.
• 🔹 NTFS — Not recommended for Android, as the system does not support writing to such cards.

If you buy a new card, you usually need to format it right on your phone.

1. Insert the card into the slot (located under the cover next to the SIM-card).
2. Go to Settings → Storage → Memory Map.
3. Click Format as internal storage or Format as portable.

⚠️ Warning: Formatting as internal storage encrypts the card and links it to the phone. Once extracted, the data will not be available on other devices! Use this mode only if you plan to keep the card permanently in Redmi 7A.

For most users, the best option is portable storage (FAT32/exFAT). It makes it easy to retrieve the map and read it on a PC or other gadget, but not all applications can be migrated to the computer. SD-The map is the limitation of Android 9 Pie.

2. Transfer files through the standard MIUI Explorer

The easiest way to move photos, videos or documents is to use the built-in File Explorer.

1. Open the Files app (the folder icon on the desktop).
2. Go to the Internal Memory section and find the folder with the files you want (for example, DCIM for a photo).
3. Press your finger on a file or folder to select it, then mark the rest.
4. Click More → Move (or Copy if you want to leave the original).
5. Select a Memory Map and specify the target folder (for example, create a Photos folder).

If you're transferring a lot of files, it can take a few minutes. Don't interrupt it, otherwise some of the data might get corrupted. Once you're done, check that the files actually show up on the map -- sometimes MIUI shows an error, but in fact the transfer was successful.

Constraint: You can't transfer applications or their data through the Explorer (e.g., game cache), and you need other methods, which I'll talk about later.

3. Transfer applications to a memory card: what can and cannot

Redmi owners 7A They often try to move applications to SD-But because of Google's policy on Android 9 Pie, it's not possible for all programs:

• 📱 Applications that explicitly support this feature (such as certain games or instant messengers) are limited to.
• 🚫 Cannot be moved: System applications (Settings, Phone, Google Play) and most of the software from the Play Market, unless the developer has added support.
• ⚠️ Risks: Transferring applications to a card can slow them down because the read/write speed of a microSD is lower than that of internal memory.

To check which applications can be transferred:

1. Open Settings → Applications → Application Management.
2. Select the app you want (such as WhatsApp).
3. Click Warehouse → Change → Memory Map.

If there is no Modify, the application does not support the transfer, in which case it is only necessary to clear the cache or delete unnecessary programs.

💡

If the application is slow after transfer to the card, try to return it back to internal memory. To do this, repeat the steps above and select Internal Memory instead of the card.

4. Using a computer to transfer data

If you need to transfer a large amount of files (for example, a backup or a music collection), it is more convenient to do it through a PC. USB-cable (combined with Redmi) 7A) and a computer running Windows, macOS or Linux.

Step-by-step:

1. Connect your phone to your computer using a cable.
2. On your phone, select File Transfer (MTP) (will appear in the notification curtain).
3. Open this computer (Windows) or Finder (macOS) and the Redmi 7A device will appear on your computer.
4. Copy files from the phone’s internal memory (Internal Storage folder) to the memory card (SD Card folder).

Important nuances:

• 🔌 If your computer can’t see your phone, try another one. USB-cable (sometimes cheap cables only support charging).
• 🛡️ On Windows, you may need to install Xiaomi drivers (download from the official website).
• 📁 Some folders (such as Android or Data) may be hidden – enable the display of hidden files in Explorer settings.

⚠️ Note: When connecting through MTP If you need to move tens of gigabytes, you'd better take the memory card out of your phone and put it directly into your computer through a card reader.

5. Automatic transfer of photos and videos from the camera

If you're actively shooting on Redmi 7A, your internal memory fills up quickly, so that new photos and videos are immediately saved to the map, set up the camera:

1. Open the Camera app.
2. Touch the badge. ⚙️ (Settings) in upper right corner.
3. Select a Retention Site → Memory map.

After this setup, all new images will be saved to SD-map, but the old photos will remain in the internal memory, they must be transferred manually through the conductor.

If the Memory Card option is inactive (grey), it means:

• 🔘 The card is not inserted or formatted.
• 🔘 The card is formatted as an internal storage (in this case, all files are already stored on it).
• 🔘 The map is damaged – try formatting it again.

6. Data transfer through third-party applications

If standard methods do not fit (for example, you need to transfer the cache of games or large files), you can use third-party utilities. 7A:

To transfer the cache of games (for example, Call of Duty Mobile or PUBG), you can use AppMgr III:

1. Install an app from the Play Market.
2. Open it and select the Moving tab.
3. Find the game in the list and click Move to SD-map.

If the game doesn't start after transfer, put it back into internal memory. Some games (especially online) block external drives.

💡

The app side cannot bypass the limitations of Android 9 Pie, they only make it easier to transfer data that is already allowed by the system.

7. Mistakes and problems when working with a memory card

When you migrate data to Redmi 7A, users often encounter common errors, and let's look at the most common and ways to solve them:

• 🚨 "Memory card is damaged" - try formatting it on your phone. If it doesn't work, the card may have failed (check on another device).
• 🚨 "Not enough space on the map, even if the map is empty, MIUI It reserves some space. Try moving files one by one or use a larger map.
• 🚨 "The files disappeared after the card was removed, most likely the card is formatted as an internal storage, in which case the data is encrypted and only accessible on this phone.
• 🚨 "The app doesn’t work after the transfer – return it to internal memory or clear the cache (Settings) → Annexes → [name] → Clear the cache).

If the phone doesn’t see the memory card at all:

1. Reset the device.
2. Remove the card, wipe the contacts with dry cloth and insert back in.
3. Check if the card is inserted correctly (chip up).
4. If nothing helps, the card could burn (especially if it is cheap or fake).
