Even after installing basic applications, there is critically little free space, especially if you actively shoot photos, download music or use instant messengers. The microSD card is a salvation, but not everyone knows how to correctly transfer data to it without losing quality or malfunctioning your phone.

In this article, we will discuss 5 working ways to transfer information, from standard MIUI functions to little-known life hacks, which files can be moved without risk and which are best left in internal memory, how to avoid errors in formatting a map and why some applications refuse to work with SD. We will also compare the transfer speed through different methods and give recommendations for choosing a memory card specifically for the Redmi 7A.

• 📁 FAT32 — Compatible with all devices, but does not support files larger than 4GB (High-Res video issues).
• 📁 ExFAT is the best choice for Redmi 7A: No restrictions on file size, high read/write speed.
• 📁 NTFS — It is not recommended because MIUI It may work with her unsteadily.

If you're new, your phone will suggest you format it the first time you connect it, and if you're using it from another device, format it manually.

2. Go to the Device section and select the file folder (e.g. DCIM for photo or Download for downloads).
3. Press your finger on the file to select it, or click "Select" in the top right corner for multiple selection.
4. Click "More" (three dots) → "Move".
5. In the list of locations, select Memory Map and specify the target folder (or create a new one).

The transfer speed depends on the class of the memory card. Redmi 7A optimally use microSD Class 10 or UHS-I – they provide write speeds up to 90 MB / s, which is 2-3 times faster than Class 4 cards.

⚠️ Note: Do not carry the Android folder manually, this can disrupt the application. Use method 3 or 4 to transfer these applications.

Method 2: Automatically transfer photos and videos through camera settings

If you need to make room for new pictures, set the camera to save files immediately to the memory card.

1. Open the Camera app.
2. Touch the gear badge (⚙️) top-right.

⚠️ Note: After transferring the application to the memory card, it can work slower, especially if you use microSD Class 4. For comfortable work, choose cards with read speeds from 80 MB / s.

Method 4: Transfer files through a computer (the fastest method)

If you want to move a lot of data (like movies or backups), you'll be more comfortable using a PC, which is 3 to 5 times faster than transferring it over your phone.

• 🖥️ Computer with Windows, macOS or Linux.
• 🔌 Cable USB Type-C (Combined with Redmi) 7A).
• 💾 Card reader (if the computer does not have a microSD slot).

Step-by-step:

1. Connect Redmi 7A to your computer via cable. On your phone, select File Transfer (MTP) mode.
2. Open This Computer (My PC in Windows 7) and there will be two devices: the phone’s internal memory and the memory card.
3. Copy files from your phone to your computer (for example, to a folder on your desktop).
4. Remove the memory card from the phone, insert it into the card reader and connect it to the PC.
5. Transfer files from the computer to the memory card.

Advantages of the method:

• ⚡ The speed of the transfer is limited only by the possibilities USB 2.0 (up to 480 Mbps) and memory cards.
• 🔄 You can copy files from your phone and to your card at the same time without taking up space in your internal memory.
• 🛠️ Easy to use with large files (for example, video in the 4K).

Method 5: Using third-party file managers (for advanced users)

The standard MIUI conductor is not always convenient. Alternative managers such as Solid Explorer, FX File Explorer or Total Commander offer advanced features:

• 🔍 Packet transfer of filter files by type (e.g., only.jpg or.mp4).
• 🔄 Synchronize folders between internal memory and card.
• 🔒 Encrypting confidential files before transfer.
• 📊 Analysis of occupied space with visualization of large files.

Example of transfer via Solid Explorer:

1. Install the app from Google Play.
2. Open the side menu and select “Inner Memory”.
3. Find the files to transfer, pinch them and select “Move”.
4. In the second window, select Memory Card and specify the destination folder.
5. Confirm the action – the files will be moved without making copies.

Warning: Some managers (e.g. ES Explorer) contain ads and may request unnecessary permissions.

💡

The file managers are convenient for working with large amounts of data, but do not give advantages in speed compared to the standard MIUI conductor. Their main advantage is the flexibility of settings and additional functions (for example, cloud synchronization).
