hi all, its me again

here is the question (and i searched all over the web and found nothing):
Is it possible in the setup project to check if a file already exists on the user machine. if it does, then do nothing. if it doesnt, then put a default file.

ie. if a database exists, i dont want to overwrite it. i only want to put it in, if it DOES NOT already exists.

is there any setting in the setup project that i can set? maybe a condition (if so an example would be very very very helpful)?

thanks in advance.
