My old PC crashed, luckily I saved my APP Data folder which has a copy of the system certificates and Keys folders. In my old pc I encrypted all my family photos on my External Hard drive and now cannot access it. Is there any way to use the system certificates and keys files to access the External Hard Drive. I noticed that I have to export these keys first, before importing to my new pc, unfortunately I cannot log into old PC to export certificates. I am using Windows 7. Can anybody advise a way to export these certificates that were saved or to import them?
