DirDate is a command line tool that can easily be automated to change folder and file last modification date, creation date or last access dates. It can use a reference file (where you 'lift' the date from an existing file), the current date/time or a series of YEAR=, MONTH=, DAY=, HOUR=, MIN=, SEC= and MSEC= commands.

It can process files in subfolders, handles read-only files and it has a preview mode so that you can see which files will be modified.

The -DIRFIX mode can intelligently set folder dates after a backup/restore or copy has reset all folder creation dates.

The -REPORT saves dates from one folder and then applies them to a new folder. This is extremely handy for saving folder creation dates from an old computer when you copy photos, documents etc across to a new computer, as the folder creation date is NEVER preserved by file copying software.

New! Unicode filenames are supported.

You can set file date and times right down to the 0.1 microseconds (100 nanosecond increments), or even tweak existing times up and down.
