Again though, the fact that it is a pdf might throw it off. Let me know if it works for you. If not, I'll have to come up with something else.
EDIT: And it does. So, apparently batch files cant read pdfs. Uhm, I'm all out of suggestions, but I'm sure else someone here would be able to help.
Can I put a question here?
