1. i have an access database set up with a pdf file link in one field

on the actual page the user has the option to view the pdf or save it.

my question is that i want to be able to show the actual file size of the
pdf to the user before they download it, is there an easier way of doing this
than just adding a file size field and doing it manually. (pdf file sizes are
800K - 10M)

2. I have the download link for the pdf on a detail page. not every item has
a pdf. i want to only show the download link when there is a pdf and just show
nothing for that field if there isn't a pdf.

any help would be great

thanks
