Features
Drag in files or whole folders, choose an action, preview the result, and apply in one batch.
Stamp any file or folder with an exact creation and/or modification date and time.
Add or subtract days, hours, minutes and seconds from existing dates.
Copy creation to modification (or back), or lift both dates from another reference file.
Clear dates entirely — the Finder then shows the item as -----.
See exactly what each file's new dates will be before you apply anything.
Process many items at once. Impossible dates are auto-corrected, and changes are confirmed before writing.
Remove dates
The Remove dates action clears the selected dates, so the Finder shows the item as -----.
