No, you cannot move the Safe Folder to an SD card. Google’s security architecture requires the Safe Folder to stay on internal storage because it relies on your phone’s specific hardware encryption chip. Since SD cards are removable, they aren't considered secure enough for this feature. If you move files to the card, they must be "moved out" of the Safe Folder first, which removes their password protection. Use your 1TB card for large, non-sensitive files (like games or movies) to free up internal space for your protected data.
