<human>: Can you condense the text into three sentences or less?

My father in law needed help reformatting his hard drive and I offered to do it because I know how. Was having lots of problems taking the files off to reformat so I decided to take half of them off and leave the rest for my partners computer to take. I was checking out the folders and found a folder named [partners brothers name]. Inside the folder was heaps of child porn and stuff titled incest and stuff.

I was freaking out because my partners brother was literally in the next room and I didn't know what to do (we live together) I was shaking because I'd seen what was in the folder quickly and I was scared. I decided I couldn't wait for my partner to get home and went and told his father (who I'm very close to). He was extremely shocked and now we're waiting for his wife (partners mum) to come home to see what to do, she won't be home until tonight

Did I do the right thing? What is going to happen now? I don't think they will go to the police with it, but I think things will change, I want to have kids with my partner one day and I can't ever see myself bringing my kids around him now.
<bot>: Found child porn on my brother in laws computer who we live with, told my father in law. I'm worried if I did the right thing and what to do now?
