!Q-Lock enables you to encrypt all your sensitive data or to retrieve it, in a very simple manner. You can encrypt and decrypt not only single files, but whole directory structures in one operation. The encryption will completely hide not only the data, but also the nature of the directory structure, the filenames, etc. As an added bonus, !Q-Lock automatically erases all traces of the original files from the disc after they are encrypted (not simply by "deleting" them), making it impossible to recover them by any "undelete" utility. Like the encryption itself, this is done with a "military" level of security.
