Folder Dater

Folder Dater sets a folder’s modification date or creation date attributes based on the attributes of its descendants.

All changes can be previewed in the Finder and undone before quitting Folder Dater. Sorting in the Finder by 'Date Modified' or 'Date Created' is useful for documents, but it is less useful for folders. Folder Dater is designed to make the modification and creation dates of a folder more useful by setting them based on the attributes of the items it contains.
