asking google:

"The  new version of Robocopy that comes with Windows Vista allows you to  copy the folder timestamps if you use the /DCOPY:T switch. The XP  version of Robocopy is unable to do this." see http://www.dslreports.com/forum/r20186464-Copy-a-folder-and-retain-the-creation-date

or from wikipedia:

.. preserve original directories' Timestamps (/DCOPY:T - requires version XP026 or later):

see http://en.wikipedia.org/wiki/Robocopy

Hi,

why not use EMCOPY ?

It keeps these attributes, and is really fast.

Hi.

You can also try an sync tool like Microsoft's SyncToy. In my test it worked (between 2 folders of my pc, no celerra for testing).

By default, it preserves the timestamps. You just need to select the right folders.

good luck
