command line - Robocopy to copy only new folders and files

To find all new files and subfolders under some root folder (let us say Documents) and to copy them to other disk (J: in this case)

Command line used:

robocopy c:\users\valery\documents j:\robocopy /XO /E /MAXAGE:20131030 /XD

Result: A full folders tree created. Only new files copyed, as supposed. It's good

A point is, that I do not want to create all subfolders on a target disk, if there are no new files in them.

Results are acceptable, but there is a lot of work to go through all folders and to find new files, as well, as to understand, what subfolders are a new ones

Answer

You can add /S for that. You don't need the \E which is for copy empty directories. You won't even need the \XO which is done by the \MAXAGE.

/S :: copy Subdirectories, but not empty ones.

When no files are copied in a directory, the directory is not created on the destination.

robocopy c:\users\valery\documents j:\robocopy /S /MAXAGE:20131030 /XD {directories_to_exclude}

If you don't have directories to exclude you can just use:

robocopy c:\users\valery\documents j:\robocopy /S /MAXAGE:20131030

You can do a robocopy /? for all the help.

 /S :: copy Subdirectories, but not empty ones.
 /E :: copy subdirectories, including Empty ones.
 /XD dirs [dirs]... :: eXclude Directories matching given names/paths.

 /XO :: eXclude Older files.
 /MAXAGE:n :: MAXimum file AGE - exclude files older than n days/date.
