Something we particularly like about this program is that if your computer reboots while a drive is mounted and readable, it automatically dismounts and becomes unusable until the credentials are entered again. It can then be dismounted in seconds, which renders the drive and all data on it unusable until the password or keyfile(s) are entered.

There is no need to decrypt the whole drive just to access the files. Keyfiles can be in the form of files or folders and, if set up as such, are required before mounting or decrypting a volume.ĭata on a volume encrypted using DiskCryptor can be viewed and modified while the drive is mounted. In addition to password protecting a partition, you can even add one or more keyfiles to it for increased security. It's also really simple to use and has some pretty neat, unique features. It lets you encrypt the system/boot volume as well as any other internal or external hard drive. DiskCryptor is one of the best free disk encryption program for Windows.
