From Marcel Scheitza:
"Virtual Safe Professional" encrypts data and protects it from the prying eyes of unauthorized persons. When you have created a virtual safe, important documents, password files or personal data can be stored in the assigned safe directory. The AES-128 and AES-256 encryption algorithms ensure reliable protection. Virtual Safe Professional also includes a built-in backup manager: The software automatically creates backups when opening or closing a safe. The backup location and the backup interval can be defined by the user.
