Digital Workshop

I have some contradicting information concerning the file size of published projects. I've just finished a project with about 70 pages , text, vector images, a few pictures but no sound or video. When I publish it the dialog box shows : Writing final file : 3856 K

When I look at the file size in the Explorer the exe has 5790 KB. Why such a big difference ?

I think the Opus player is 1955KB, so that would explain the difference.

Thanks I thought the size displayed was the size of the whole pub, so it's only probably the contents of the pub without the player.
