Hard drive crash

I recently had a hard drive failure and had to replace it.  Was running windows 10, but program was corrupted so I started with a fresh copy of that as well.  I had no Basecamp backup of My Collections, but I did have my entire hard drive backed up.  How do I find my Basecamp data files in my backup drive and can I get them back into my current copy of Basecamp without having the actual Basecamp backup file?
