This makes perfect sense, but the issue I have is that if I load
the main cell, then try to expand, magic can't find the files to 
load them into memory, presumably because it is misinterpreting 
file name as a variable.

I will try the gds flatten on option, I think this will also solve
my other issue of moderate amounts of drc violations that magic sees
that aren't really there.
