If you're worried about storing your data and files, why not create a virtual encrypted drive to store your important data?

Even if someone manages to hack in to your computer or, in the worst case, your machine is stolen, the hacker wouldn't be able to access any of the encrypted files.

CryptoExpert creates encrypted virtual disks and these disks are visible as usual disks with drive letters (for example, G:, H:, Z:, i.e. with any drive letter that isn't in use by other system devices).

The data stored on a CryptoExpert 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 CryptoExpert.

Any free drive letter (or chosen letter) in the system may be used to mount and to open an encrypted file-container for access.

When your virtual disk is opened, you can read and write data as if it were a conventional removable disk.

You can do anything with a CryptoExpert virtual drive that you can do with a normal hard drive, but with CryptoExpert, the encrypted volumes require password authentication before the files become accessible.
