Is it possible to share files between two apps?

My scenario is this: I want to create a free/demo version of my game
and a complete version. The player should be able to play the free
version, then upgrade to the complete and continue where the free
version ended - ie. the complete version would need to load a savegame
created by the free version.

All answers appreciated!

Best regards,
Viktor Linder
