You'll be using GtkTreeIter *. Please look at the API docs
http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeModel.html. These
should always be your first resource. As far as file formats, I think
he's referring to whether you want to save normal C structures to disk,
save some kind of line-by-line thing, use XML, use SQLLite, etc. XML is
extremely versatile, but it can be kind of tricky to learn. Check out a
parser like the following: http://www.xmlsoft.org/. Your basic structure
will be:

OPENING:
Access the file for reading
for each item in file
append item to treeview
Close the file

SAVING:
Access the file for writing
for each item in treeview
append item to file
Close the file

Again, the API docs are your friend.
