Problem with Encrypted Files

Hi,

I use Windows XP Pro SP2. I had this bunch of photos in a folder and I was just fiddling around with the folder properties. I'd turned on the 'Encrypt files to secure data' option on the folder, leading to all the files in the folder getting encrypted.

I hadn't accessed the folder in quite some time. Now, when I try to, I am unable to view any of the images in the folder. They show up in green, obviously because they're encrypted. But when I open any image, the Windows Picture and Fax Viewer says 'No Preview Available'. Neither do the other image viewers work. Also, thumbnails of the pictures fail to show up when I use the thumbnail view.

I am also unable to remove the encryption. When I uncheck the Encrypt option, a box pops saying, 'An error occurred applying attributes to the file...' and that 'Access is denied'.

Any fixes please?

Thank you.

Re: encrypted files

Encryption is on a per-user basis. It should work as long as you're the same user on the same machine. Are you?

And just as precaution: http://support.microsoft.com/kb/241201/ tells about backing up the encryption key.

The recommendation in such a case is to get the unencrypted originals from your backup. Having such a backup (burn to 2 different CD's or DVD's and store those on two different safe places) is highly recommended. May be too late, however.

Re: encrypted files

Sorry. But I am not really able to follow. Yes, I'm accessing the folder from the same user account, but I haven't set any encryption key earlier.

Sadly, I do not have a backup of the folder. Can you please elaborate?

Thanks.

Re: encryption

Now I realise what has happened. I'd enabled encryption on these files quite some time back. After that I had formatted my OS partition. I'm guessing that would have reset my encryption key? Is that why I'm unable to access these files now?

Is there any other way to make this work?

Thanks.

Yep.

Formatting erases the encryption key made and stored by Windows. That's why you should have made a backup of it before the format and restored that after the format.
Windows behaves as designed here. But you didn't, so to speak.

Now head to lostpassword.com. Or accept the loss.
