Dia file is a text, unless you embed a ton of binary data.
But.

To export your diagram to the file (often a bitmap file), you need to first
render it as a whole (or as much as you want exported) on canvas in memory,
thus the size prediction is rather accurate... For a rendering buffer.
The following compression may only reduce the resulting file storage size.
