Re: [foxboro] Copying Displays to remote workstations

I don't think the files are station specific. It seems to send only what
you would expect. You can get it to list the files that it is updating
and they are only the files that you can verify that have changed.

We keep central copies of all our graphics for changes. These are then
distributed to the relevent workstations. The central copies are on a
different node to the final location and still only the changes are
sent.
