DOS does not provide any capabilities to change the date of directories or
volume labels, and this is the gap that DirDate fills. DirDate can change
any part of the date and/or time on any disk file, directory or volume
label, whether it is located in the root directory or a subdirectory. It
can be used to indicate to search utilities that the contents of a
directory have been updated. DirDate skips altering Windows 95 long
filenames. Any part of the date and/or time can be set to the current
date/time, or to a specified value. Dates may be set to the same date as
that of a reference file, or to the date of a reference file modified by
subsequent values.
