How to recover lost Windows EFS certificate

Hi. I was using Windows 8.1 installed on my C: drive a few days ago. It got infected with virus so I decided to install Windows 10. I formatted my C: drive and installed Windows 10 on it. Once I opened my Windows and went to E: drive, I recalled that I had encrypted everything using EFS and had forgotten to take a backup of the certificate and now I need to recover it somehow.

Very little space on C: drive has been overwritten. I ran a deep scan to recover files and found about 3M files on it. Is there a way I can find out the certificate file? Any pattern or extension I should be looking for? I've already tried .efx but it gives nothing. Is there any other way to recover the certificate?

If your EFS certificate is lost or damaged, it is not easy to recover, try some third-party data recovery software, it might be possible.

As I said before, I have recovered almost 3M files using a thired-party software but I don't know how a certificate looks like so I can't search among them.
