Trial version is free for 30 times, and you can only decrypt but not encrypt files and folders once the trial period expired. And thus, some features such as First Aid Center and Modify Admin Password are not available for the trial version.
After you purchase the program, you will be provided the activation code which will unlock these limitations. A set of USB Encryptor includes 10 activation times, that is, you can use it on 10 USB drives and external hard drives at most.
While if your USB drive is formatted, damaged or lost, the activation information will be invalid. 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.)
