Download a stack file

How, exactly do you implement Load? I need to get a stack file from the server on to the local machine. I seem to be able to load it into memory, but can't actually see the stack or save it to disk.

I've done both methods for storing data; both times for "books" with a lot of text, pictures, and audio/video. Working with internal data is just a LOT faster and simpler for this sort of thing.

For this update, I need to save out and restore the user's "magic marker" hilites of the text--it's a textbook app.

I always save data in files external to the stack and have that data pulled in at preopenstack.  So I never have to do a stack to stack transfer of data or stack renaming.  Not saying this is the best way, it is just the way I do it.  Yes, load is what I use.  Works well for me, though recently have encountered IT policy that is quarantining updates.
