"EFS" Encrypted files

[Amir M Ebrahimi]

Hello guys, I had some files encrypted with cipher cmd command on an external hard with FAT32 format. one day I had to copy a large file on that hard drive and I reformated the hard drive to NTFS format. after I reformated the hard drive my encrypted files were somehow broken. the result was my files got a *.pfile extension and a $EFS file was created in each folder and they are no longer encrypted. anyone have any idea what should I do to get my files up and running again?

Hello mate, thanks for your time but the solution you gave me didn't solve my problem 🙁

If you did not backup your EFS/recovery keys / private key than you are out of luck as they are needed with your password to decrypt the files.

I Have a backup of the key, my files are broken. the thing happened it was that the files are no longer encrypted when i look at them in the advanced options of the file. but they have this .pfile extension.

Maybe you just need to change the extension to what the files extension would have been before you encrypted them. If not than hopefully someone else has some more helpful advice.
