If you were content to simply have the user pick among all files in
the folder last visited, you could simply set the defaultFolder to
the folder containing the last file selected after each selection.
Placing a list of the files in a field may seem like overkill; but it
allows additional options. Example:
With SDB's folder archive stack the user can deselect/select
individual files by clicking on them and folders by ctrl-clicking on
any file in a folder. Deselected items are colored gray; selected
items inherit the field's textColor. You could use the same
technique to mark which files on the list have already been visited.
