Example
1. Copy directory contents of MyFolder to YourFolder (including file data, attributes and timestamps), recursively with empty directories (/E):
Robocopy C:\MyFolder C:\YourFolder /E
2. Copy directory recursively (/E), and copy all file information (/COPYALL, equivalent to /COPY:DATSOU, D=Data, A=Attributes, T=Timestamps, S=Security=NTFS ACLs, O=Owner info, U=aUditing info), do not retry locked files (/R:0)(the number of retries on failed copies default value is 1 million), preserve original directories’ Timestamps (/DCOPY:T – requires version XP026 or later):
Robocopy C:\MyFolder C:\YourFolder /COPYALL /E /R:0 /DCOPY:T
3. Mirror MyFolder to YourFolder, destroying any files in YourFolder that are not present in MyFolder (/MIR), copy files in restartable mode (/Z) in case network connection is lost:
Robocopy C:\MyFolder \\networkserver\YourFolder /MIR /Z
