John's eyes lit up. "Okay, I think I can handle that."
Mike nodded enthusiastically. "That's the one! It was a bunch of files zipped up into a .rar archive. I was trying to send it to you for the project we're working on, but I must have gotten the email addresses mixed up."
John's eyes widened. "Was it a big file? Maybe a .rar file?"
As he pondered what to do with the file, John's coworker, Mike, poked his head into his cubicle. "Hey, John, I think I might have sent you a file earlier today," Mike said. "I was trying to send it to our team, but I think I might have accidentally sent it to you instead."
John tried to open the file, but it wouldn't budge. He had no idea what it was or what it was supposed to do. He tried to search for information about it online, but all he could find were vague references to it being a part of a larger archive.
