With Advanced Crypto Drive you can keep your confidential data - documents, letters, photos, videos, programs and any other files and folders strongly protected on virtual encrypted disks. Such disk has no differences from any other physical hard disk drive but it supports transparent on-the-fly encryption to keep secret data strongly secured. An encrypted virtual disk is simply a file that ACDrive mounts as an additional drive letter on your machine. You specify the pass phrase when the virtual drive is mounted and thereafter everything you access from there is automatically decrypted and anything you place there is encrypted. Main features of the program: Easy-to-use and reliable software Transparent on-the-fly encryption AES 256-bit strong encryption algorithm Password protection of secured data Compatible with USB drives Works with all Windows applications Network support for virtual drives
