Final answer:
To move a Secure Folder to an SD card, you must back it up to Samsung Cloud, remove the current Secure Folder, and then restore the backup with the SD card set as the storage location. Direct transfer to the SD card is not allowed for security reasons.
Step-by-step explanation:
Transferring a Secure Folder to an SD card on a Samsung device requires a few steps. Firstly, you'll need to open the Secure Folder on your device. Inside the Secure Folder, select the three dots at the top-right corner and choose 'Settings'. From there, you can access the 'Backup and restore' option. While Samsung does not allow transferring the Secure Folder directly to the SD card for security reasons, you can back up the contents to Samsung Cloud, remove the Secure Folder, and then restore the backup after setting the SD card as the storage location.
Please note that Samsung's security protocol is designed to protect the data in the Secure Folder, including against moving to external storage directly, which could potentially be less secure. Therefore, the process is intentionally restrictive to ensure the security of the data contained within the Secure Folder.
