BestCrypt creates and supports encrypted virtual disks. These disks are visible as regular disks with correspondent drive letters. The data stored on a BestCrypt disk is stored in the container file. A container is a file, so it is possible to backup a container, move or copy it to other disk (CD-ROM or network, for instance) and continue to access your encrypted data using BestCrypt. Any free drive letter in the system may be used to mount and to open an encrypted file-container for access. When the virtual disk is opened, you can read and write data as if it were a conventional removable disk.
