How can change the encryption

[BioSs]

I have some family pictures were set a encryption using WinXp OS. Now the laptop has been broken for while, so i toke the HD out and run it as external drive in Win 7. I can't open these pictures under win 7. It required to remove or get permission or so.. How can i do that? I have tried right click and property and security and allow full control on these pictures but no luck.. any suggestion one?

Whoever set the encryption has to authorize the unencryption. It is hard to understand why anyone would encrypt family photos. If they wer DES encrypted, who ever did it has to undo it.

In XP it could have been done by Microsoft EFS or TrueCrypt. In either case, you must have the password or you're hosed.

If you used the NTFS built-in encryption you need the private key from the XP installation to decrypt those files, the only other method would take bruteforcing the key which would likely take decades or longer. Isn't that the whole point of encryption?
