Hallo Günther.

I'd suggest you read in the "GLib Reference Manual", about IO Channels.
These utilities kind of standardize file access, and permit you to define
your IO operations asynchronously. You can -fairly easily- define a
callback function which gets called each time a chunk of file gets
transferred, so you can provide a new chunk (and update your progress
bar).
