You will get one activation code if you purchase a set of USB Encryptor. The one code includes 10 activation times, that is, you can use it on 10 USB drives and external hard drives at most.
With the 10 times used up, you will have to purchase the program if you continue to activate more USB drives. (Note: If your drive is formatted or damaged, it needs to be activated again.)
