Design a table to include external file links

I'd like to create a table that has two/three fields. 1) a description of
what the linked file is and 2) the hyperlink to the file. I'll have one more
field to identify to a primary record from another table.

With hyperliniks (as far as I can tell right now), it tries to open a file
right after the hyperlink has been clicked. I have a problem with that since
some files are not in a format that can be read by regular software. What
I'd like to do is once the hyperlink is clicked, have the program pop up a
message window asking wether to open or save this file to disk.

Would there be a fairly easy way to do this?
