If you copy a folder in windows, you may notice that the newly copied (created) folders will have the timestamp when the copy was done (not the original timestamps from source). However, the files inside would have kept the original timestamps.
To have the folder (directory) timestamp as well to reflect the same as the source folder, do below in command line
Robocopy E:\Source\Dir1 D:\Dest\Dir1 /DCOPY:DAT /COPY:DAT /E /R:0
Note: If you already had copied the files using explorer, this will not copy the files again. It will check all and copy only if there is a newer file; plus (more importantly) will also update the destination folder with source folder time stamp. It ran much faster too as it didn't do any new copies... just had to set the timestamps
