Important Notes

1. Default Format: The card comes pre-formatted to FAT32 for computer use. If your device doesn’t support FAT32, you can reformat it to exFAT or NTFS.

2. Incompatibility: This memory card is not compatible with Nintendo consoles or other gaming systems.

3. Capacity Discrepancy: Flash memory products follow the decimal storage standard (1MB = 1000KB, 1GB = 1000MB) during manufacturing. However, operating systems use the binary system (1MB = 1024KB, 1GB = 1024MB), which causes a slight difference between the displayed capacity and the labeled capacity.
