I have a macro that creates a menu (word doc) of the folders and files in a nominated directory. I extract some properties for each document found and would like to add a field that calculates the age (in days) of a each document i.e. Current Date - Last Modified Date. As the menu may only be seldomly generated (to update a new file added or removed) I figured a field was the only way to reflect the age of each document when the menu was next opened...which may not be true, in which case I guess there would be no way to reflect the age?

Any feedback gratefully accepted.
