To get more of these below you can run in cmd or powershell robocopy /?

/TEE = spit out to console.
/XF pagefile.sys - this excludes files like pagefile.sys. use space in between files to ignore.
/SEC - copy over security
/XD - we do not want to copy these directories. (Exclude Directory) space seperated list.
/E - copy subdirectories including empty directories
/NP - No Progress (don't display percentage copy)

***Potential Danger - see below link on unbuffered I/O and consider omitting for network copies of large files
 /J :: copy using unbuffered I/O
