One click packages the file into an encrypted file using the FileEncrypt proprietary format. This provides a better encryption method and protects the file from unwanted access.
I was searching for a good password-protected encryptor app. This app is a must-have solution that does exactly that. No need to use terminal or diskutility (two of the most common methods) to lock a folder. Just set one master encryption password and you are good to go. User friendly app.
