Any number of folders with all subfolders (even on different drives) can be moved in a highly scripted container file (created with TrueCrypt). This can be opened with password/USB-Device if needed, this container file will mount as another drive. When moving the data is first copied, while no error occurs, the original folder is deleted, at the direction of the container, the data can be shredded with the ERASER program. With automatically generated junctions stored in the container file folder in the PC file system are displayed. In this state you can work as normal with the stored data, En/decryption is performed "on-the-fly", the data in the container will always be encrypted. As long as an application accesses the lists of container file that TrueCrypt prevented the closure of the container, it is an indication, and the question whether the closing is to be forced, therefore accidental closure is not possible. The container file can be deactivated at any time, so that all folder invisible (junctions) are deleted, all data is securely encrypted in the container file. This also happens automatically when the PC after a normal stop or a crash starts up again, the container file has to be remounted in each case, a forgetting of the activation of the protection is thus excluded. Since surviving the junctions restart automatically when installing the automatic launching of DirCryptHide registered in the Registry. The program deletes the invalid junctions, and terminates immediately. The location of the container file can not be ascertained. After starting the program and entering the password/USB-Device written on the top left program window. The loss of the password means in any case, the loss of data in the container file.
