Thanks!
actually -
I think the simplest method is:
On Server startup - set interprocess variables with which ever folder
paths I want.
Use Get Process Variable from client to grab these values when needed.
Since in this instance there is nothing dynamic (i.e. changing during
execution)
The various folder paths will be the same on the server from server
start to server shut down.
Then I have no need to worry about asynchronous behavior
