LockDisk creates a volume (vault) that can only be accessed with a password. This volume stores files in the encrypted form. Once mounted, the LockDisk drive is like any other drive you normally work with. It functions like any other drive (C: or D:) on your computer. Just drag and drop any file into the LockDisk Vault. It is automatically encrypted. It's that simple! LockDisk vaults can only be viewed, accessed, browsed or modified by the user who has the key to open it. At other times, the files are invisible!
