Q. I have 2 directories that I'm combining (eg: from 2 backups), some files are newer, some are older, butI only want to copy the missing files to the destination. How do I do that?

A. Robocopy has a few flags that are useful for ths situation:

robocopy C:\Source D:\Destination /E /XC /XN /XO /R:1 /W:1

Where:

/e Copies subdirectories. Note that this option includes empty directories

/xc Excludes changed files.

/xn Excludes newer files.

/xo Excludes older files.

R and W are just retry and wait (in case a file is locked). This is not neccessary in this situation, but we include it as a force of habit, to skip unreadable files.
