robocopy
I wanted to run a program from my local pc, so I copied the entire data folder using Robocopy. I then compared the size of one of the files in the source
using the Status utility to the destination. The destination file size was smaller than the source! Any idea why this might happen. A subsequent windows copy
worked just fine.

My first guess is that the source and destination drives use different cluster sizes and what you saw was the size on disk rather than the actual size.
