Re: Encrypted Files from a formatted drive

Without a RA the only way would be if the user that created the EFS files
had exported their EFS certificate/private key to a password protected .pfx
file for safekeeping for and event like this. Also if there is a copy of the
user's profile somewhere in a backup there also may be a way to extract the
user's private key from it but my guess is there is not from your
description of the scenario. There is no backdoor way to access EFS files.
If there are no user or RA private key available then the files are forever
gone. --- Steve
