that a back up export utility would be a good idea - one that selected
all the files required. Changing file formats perhaps complicates the
issue of export/import between operating systems - microsoft bringing
out "new" versions (if that made a difference?) of it's operating system/s.
A platform independent set of data files means no matter what o/s you
choose one can switch between and share data. Core data formats could
change for improved security - whatever as long as o/s independent.
I'm not a developer :) just another end user!
