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.
