Introduction to the quick file copy tool robocopy in Windows

I used robocopy to copy the output log of the file. It can be seen that the efficiency is very good. Copy 2729 folders of 152 files in documents in 27 minutes and 59 seconds.

Robocopy isWindows Server 2003 Resource KitDownload a tool in the toolboxWindows Server 2003 Resource Kit.

SetMove the file under Z: \ _ my_mediaX: \ _ my_mdeia directory
Robocopy Z: \ _ my_media X: \ _ my_mdeia/move/E

Do not copy *. BAK files
Robocopy Z: \ _ my_media X: \ _ my_mdeia/E/XF *. Bak

Do not copy files larger than MB. The unit is byte.
Robocopy Z: \ _ my_media X: \ _ my_mdeia/e/MAX: 100000

Copy the files that have been modified in the last seven days.
Robocopy Z: \ _ my_media X: \ _ my_mdeia/S/maxage: 7/minage: 1

RH indicates the 24-hour system. The following command indicates that the parameter range is from 0000 to 2359 from AM to AM.
Robocopy Z: \ _ my_media X: \ _ my_mdeia/e/RH: 1000-1700
