Built-in 32 or 64 gigabytes are quickly filled with modern apps, system updates and, of course, high-resolution photos.

⚠️ Note: Formatting a memory card will completely delete all the data on it. If the card already has files, copy them to the computer beforehand, otherwise they will be irretrievably lost.
The formatting process takes a few seconds, but it is critical to the stable operation of the file system. MIUI will create the necessary directory structure, including the DCIM and Pictures folders, where your photos will be stored in the future.
Use of a standard conductor for transfer
The most reliable and controlled way to move photos is through the built-in Explorer app, which allows the user to choose the specific folders or individual files to move. Open the Explorer app on the home screen or in the Tools folder.
In the Explorer interface, go to the device's internal memory, and you'll need to find the DCIM folder, and inside it is the Camera folder, and that's where all the photos and videos you've taken are stored by default, select the files you want with a long press, or select the "Select All" option in the Control menu.

⚠️ Note: If the memory card is removed or damaged, the camera may stop taking pictures or start saving them to internal memory if there is still space left.
It’s worth noting that some heavy shooting modes, such as slow-motion video or high-resolution shooting, may still require high recording speeds that only the smartphone’s internal memory provides.
Transfer through the Gallery app
An alternative and more visual way to manage media files is to use Xiaomi’s standard Gallery app, which is handy because you see the photos you want to move and can sort them by date or album before transferring.
