A Sentry 2020 created virtual volume, which is presented to the operation system and all applications as a regular storage volume, just like another hard disk or a memory card. You can format the volume using any file system (like FAT, FAT32 or NTFS), then work with files on the volume using any application. All applications see just another hard disk, and work with the files stored on it as they would with any other files. In reality, everything stored on the volume is placed inside a large file and transparently encrypted/decrypted on the fly.
Encrypted volume is comprised of two files: RAW File and KEY File.
