Setup
To begin using your SanDisk Extreme microSDXC card, follow these general steps:
- Identify Compatible Device: Ensure your device (e.g., smartphone, action camera, drone, Nintendo Switch) supports microSDXC cards. Refer to your device's manual for specific compatibility requirements.
- Insert the Card: Locate the microSD card slot on your device. Gently insert the SanDisk Extreme microSDXC card into the slot until it clicks into place. If your device requires a standard SD card, use the included SD adapter by inserting the microSD card into the adapter first, then inserting the adapter into your device.
- Format the Card (If Necessary): For optimal performance and to ensure compatibility with your specific device, it is often recommended to format the card using your device's internal formatting function. This will erase all data on the card, so ensure any important data is backed up before formatting.
- Verify Recognition: After insertion and potential formatting, check your device's storage settings to confirm that the microSD card is recognized and its full capacity is available.

Capturing Photos and Videos
With UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) ratings, this card supports continuous shooting of high-resolution photos and seamless recording of 4K and 5K UHD video. Ensure your camera or drone settings are configured to utilize the card's full capabilities for optimal performance.
