I had a file which contains images and videos, I was using the windows 7 ultimate and I had encrypted the file. Now I have copied that file to my hard disk and format that operating system and again. I installed a fresh copy of operating system windows7 ultimate, now when I want to see my file which I had saved in hard disk, file is not opening and generate some permission issues.

How can I recover my data?

Can you confirm that: 1. The file was encrypted using Windows 7 Encrypting File System (EFS) by right-clicking on a file, choosing Advanced and selecting "Encrypt contents to secure data". 2. Do you have a backup of the computer before you reinstalled Windows? 3. Where did you copy the file when you reinstalled Windows? –  Bernie White Sep 22 '11 at 10:33
    
Pls add specifics on how files were encrypted (missing at time of posting this comment). –  Garrett Dec 9 '11 at 15:58

You have an option to recover your file only if the stored sector of that file is not overwritten with new data. There are some professional data recovery utilities which will help you to recover deleted file from windows 7.

In case if you are sure that the stored sector of that file is not overwritten, then download some good software, evaluate using demo version and use it to recover your file.

Good Luck.

Do you have a copy of the key?

http://windows.microsoft.com/en-US/windows7/Recover-encrypted-files-or-folders

Connect the drive that contains the encrypted file. Connect the drive that contains the backed-up certificate and key. Start certmgr.msc Import the certificate

You should now have access to the files.
