Hi Dante,
It is possible to get a URL for your file attachment you can create a formula URL field that will pull out the address for your file attachment. I typically use a formula like this:
URLRoot() & "up/" & Dbid() & "/a/r" & [Record ID#]& "/e9"
Then you just have to change e9 to be the field id of your file attachment field. So if your file attachment field has a field id of 13 you would just have /e13. Then you can export that field instead of the file attachment field and it will give you a URL. I hope that is helpful.
