When I try to decrypt
Access denied : you will need to provide administrator permission to change these attributes .

what are you using to decrypt? sound like you need to take ownership of the file first.

I used the windows encryption which made the files color green . د

Edit : yes I have full permission .

If the files were encrypted with EFS, the keys were not backed up, then the drive containing the keys was formatted, then you will never again see the contents of those files. The same can be said of BitLocker where the recovery key is not backed up and the TPM (if one is fitted) is cleared.
