You have one password protected lock, that is for the device itself.
You can set Encryption for the media card, but that will only protect it when it is installed in computer. That makes normal use difficult because your computer can not access the card for media uploads. It is valuable for Business user that will have likely have confidential attachments stored there.
I have not used this app, but it purports to do what you want. No guarantees, and make a backup before you use it in case you make something so secure that even you can't recover it: FileLock
EDIT: If your userid is your email address, you will soon start getting lots of unwelcome emails. You should PM Kevin Michaluk to change it. Mods can't change it for you.
