Incoming NoCD

[owner]

Ok, I downloaded a No CD. It's called "incomcrk". I followed the instructions on it, and it didn't do anything. I'm kind of alarmed at this point, so I've researched how to investigate what might have happened, such as trying to extract it with multiple programs and "read" it with others and nothing seems to work per se.. Anyway, from someone who is more savvy, can I please get a full answer about exactly what this file is, and what it does (to registry, or whatever)? Thanks so much in advance. I would also love to learn how to find these things out on my own, but my searches on google are leading to dead ends. Maybe I'm typing the wrong thing?
