Just a quick note to say if there's supposed to be
only one matching file, might have to be careful about the matching.
Zaxo's code will find any files which have that number string in it.
But if there are two or more, like if you have "ab123456.pdf" and "ab1234567.pdf" and "ab9123456.pdf" then you need a more detailed regex.
