Hello. My name is Blaziken. This is my first time posting here. I am fairly clueless regarding software, but I'm not a total idiot.

 

Long story short, I recently upgraded my entire computer, OS included: I went from Windows 7 to 8.1. However, I forgot to decrypt some files on my external HDD's (in fact, I forgot I had even encrypted them). As a result, I can no longer access them (obviously). Thankfully, I didn't format C: when I installed Windows 8.1, and therefore still have the .sys files in a subfolder of the "SystemCertificates" (or something like that) folder. All I need to know is how to use them, either in Windows 8.1 or 7 (my mom's computer still has 7), to (finally) decrypt my files. Some can be replaced, although it will take time, but others cannot and are very important to me.

 

I thank you in advance for your time.

 

PS: I didn't post my specs (aside from the OS) because I think it's unnecessary in this situation. If you feel otherwise, just ask and I'll post them.

From this page I believe you are out of luck and the encrypted data is lost.

 

 

 

You can lose access to encrypted files if you install a new operating system or upgrade your current one, or if your current operating system fails. The following steps can help you regain access to encrypted files.

You must have a backup copy of your encryption key and related certificate on a disc or other removable media (such as a USB flash drive) to follow the steps below.

 

 

Even though this is for Windows 8.1, I believe the information applies to your situation.

Thanks for the reply.

Isn't there some way to create a certificate using the keys I already have, or "force" the new OS to accept the keys without the certificate? As I said, I can replace some information, but the rest took me years to create, and most of those haven't been uploaded anywhere.

I found a third-party program that was able to use the keys I had to decrypt my files. It's working on them right now. It worked on my irreplaceable files, and is now decrypting my replaceable ones. Mods (or whoever is responsible), feel free to lock this thread.

It was "Advanced EFS Data Recovery" by Elcomsoft. It's expensive, though.
