Once the device is turned on, the Android system should automatically detect the new storage.

When you first connect, Redmi Note 7 will offer two options for using memory:

• 📱 Portable storage – the card is used as an additional disk for photos, videos and music, access to which all applications have access.
• 🔒 Internal Storage – The card is encrypted and becomes part of the system partition, which allows you to install applications on it, but makes it unreadable on other devices.

Selecting the internal storage mode requires formatting, during which all the data on the map will be deleted. This action is irreversible, so pre-copy important files to the computer. After formatting, the system will redistribute space, and some of the programs can be transferred to the application settings.

If you've chosen portable storage mode, you can pull the card out at any time and connect it to your computer through a card reader, which is convenient for fast transfer of large amounts of data, switching between modes is possible at any time through the settings menu, but you will need to re-format it.

Formatting and file systems

The MIUI-based Android operating system uses the default FAT32 file system for small-volume cards and exFAT for drives larger than 32 GB. FAT32 has a 4 gigabyte file size limit, which can be a problem when recording long-form videos in high resolution.

For 64GB cards and up, the system will automatically offer exFAT formatting. This standard is free of file size restrictions and supports huge amounts of memory. If your computer can't see the card after your smartphone, it's possible that your PC doesn't have exFAT drivers installed, which is true for older versions of Windows.
