I spent a bit of time figuring out how to do a mix of spaces and wild cards (*) for file names.

An example of what I found works is:

robocopy ".\Icons" "C:\Users\Public\Desktop" "Wwise "*.* /e /mt:4

The bit in Bold is the interesting bit, in that "Wwise<space>"wildcard.wildcard allows me to copy only the files starting with Wwise<space> to the location desktop. I am sure there are more ways of messing wit this, but I stopped after getting it to do what I wanted.
