Hi,

I recently format my c drive on my laptop and install ubuntu 7.04 but I forget to get the encryption key backup on windows:confused:. I can see my encrypted files on the other hdd but I can not access them I tried lots of staff to save my files but I did not success. I found out that if I can move the files to fat file system or if I convert file system to fat efs can be removed but I do not know how can I do it. Does anybody know how can I move encrypted files to fat file system? or convert file system to fat without lost my data?

Thanks for your time

Do you have a usb port and a usb flash drive? Flash drives are usually formatted as fat32, so you could try copying the files to one.

That's sort of the point of encryption.

You need the decryption key to be able to do this. Otherwise, you will simply copy an encrypted file.


but I forget to get the encryption key backup on windows
This was your mistake.

I did a little digging around. You are probably SOL.

Huh. You have not provided much detail (only your interpretation), but it sounds like you can see the files on a NTFS USB disk, you just cannot access them.

If this is the case, its probably a result of the mount not giving you this access.

Easiest way, then, would be to 'sudo cp' the files you need in:

mkdir temp && cd temp
sudo cp /media/usbdisk/where/ever/this/are .
sudo chown <myself> *

where <myself> is your logged-in id.

And go from there.

If you do this, you will lose the encrypted data.
