That's not a regular expression. I think what you want is:
listdir(r"d:\tmp", RegExp(r"\.pdf$", "i"));
In a regular expression, "*" means "zero or more of the previous
character. So, "a*" would match "", "a", "aa", "aaaa", etc.
A dot means "any character except \n", so that wouldn't work like you
expected either. You have to escape it.
A $ means "end of line", so that means that the .pdf has to be at the
end of the string, not just anywhere.
