[Sugar-devel] determine origin of file selected from an object chooser?

[Samuel Greenfeld]

As far as I know there really is no need; when your activity saves state
(when exiting, etc.), it should save the copied file as part of the
activity's journal entry.

At least this is how it has always worked with Jukebox & Read.

(As a side note, the Journal description for a copied item often states
the path where it came from, but I would not rely on this to tell you
that it came from an external source.  The description or this "feature"
could change at any time.)
