There are two editions of AEFSDR: Standard and Professional. Standard Edition works at the "file level", so the encryption keys should exist on the disk. Professional Edition has all functionality of the Standard one, but also allows to scan the disks by sectors, so it is able to find the encryption keys if they have been deleted, or sometimes after disk re-formatting or system reinstallation.
