It is important to understand that the logic of working with external drives on Xiaomi is different from other brands. + microSD), and in the default settings, the card can be mounted as portable storage or internal memory, depending on where and how the files are displayed. If you first inserted a card or moved it from another device, the system may request formatting — that's okay, but not always necessary.

1. Method: through a standard MIUI conductor

The most obvious way is to use Xiaomi’s built-in file manager, which is simply called Explorer (or Files), and is usually on the home screen or app menu.

• 🔍 At the top of the screen, select the Device tab (or Local Storage tab»).
• 💾 Scroll down, the internal memory and SD-map (can be called from a map model, such as SanDisk) 64GB).
• 📂 Click on the name of the memory card and its contents will open.

If the card is not on the list, check:

1. Physically is it inserted into the slot (sometimes the contacts are oxidized and the card is not determined).
2. Is it not formatted in NTFS — Redmi 5 doesn’t support this format out of the box (root or patch needed).
3. Is there a “Inner Memory” setting (more on this below).

Check the physical connection of the card (pull out and paste again)

2. Go to the "Memory" (or "Storage") section.
3. At the bottom of the screen, find a point «SD-Card (may be called External Memory or Additional Storage»).
4. Click on the three-point menu (⋮) in the upper right corner and select "Storage settings».
5. Here we can: 🔄 Change the format (if the card is used as internal memory). 🗑️ Format (deletes all data!). 🔗 Remove (Safe Removal).

The critical feature of Redmi 5 is that if the card is formatted as internal memory, it can't be simply extracted and read on another device. The system encrypts the data and it will only be available on this phone. If you plan to use the card as a removable drive (for example, to transfer files between devices), choose Portable Storage mode.
