ABOUT ENCRYPTION
Encryption is designed to protect data in a certain folder against being viewed by unauthorized persons even if they have
access to the device.
When you access Encryption for the first time you will have to set up a secret code (if it has not been set up earlier). The
secret code is used to prevent unauthorized access to the Encryption settings and to the encrypted data. The secret code
can also be used to access the Anti-Theft and Parental control settings.
The data in the folder will be encrypted once command Encrypt is executed and then data will be encrypted and
decrypted "on the fly" at the moment there data is placed into the folder, extracted from it or accessed.
Executable (.exe) files cannot be run from an encrypted folder.
Information about the component's work will be entered into the application log.

In order to move around the file system use the stylus or the joystick buttons of your device: Up, Down – to
move within the selected folder, Left, Right – to move one level up or down from the current folder.
3. Press Encrypt to start the encryption process.
