Searching is going through the entire C drive, so it can take a bit more time. It sounds like you did find the folder though, right?
I am not sure if I follow you. Did you manage to get it to upload into https://www.OneDrive.com? Are you running into issue signing in? I am surprised that it wouldn't let you paste directly into a reply to me. Maybe you need to include some words a long with it so you can submit. I have worked with others today and they could paste the screenshot no problem.
