Almost right: we are using hard links. In general, activities shouldn't
need to worry about the difference. However, in the context of Rainbow
(in combination with Sugar 0.82) it can get important: if the creating
activity used too restrictive permissions (umask), other activities
might not be able to update or even just read the file.

As Aleksey explained, what matters is that you keep a reference to the
DSObject.

Both are exactly the same. Accessing file_path will simply invoke
get_file_path():

sugar.datastore.datastore.py, class DSObject:
>    file_path = property(get_file_path, set_file_path)
