File size after deleting pages

[thomaso]

In a 90 pages document, 35 MB, I deleted all pages except 3. There are only 6 rectangles and 3 text frames left. No content added.
I did "Save As..." with a new name but the file size remains quite the same: shrinks from 35 to 33 MB.

Any idea how to fix this page-reduced .afpub's file size?

Even more strange: I did a Save As to the 90 pages .afpub and it shrunk to 31 MB. – Whereas the page-reduced, nearly empty .afpub refuses to shrink below 33 MB with any more "Save As...".

First thought is that it is configured to save document undo history. If that is so, then it needs to retain all the data (images, etc.) to restore should you decide to undo the deleting of pages.

No, not active. Even then it would be strange that the 90 pages mother document shrinks smaller than its 3 pages child.

I've created a document with 100 pages, image on each and saved to a 15MB file, removing most of the pages and saving sends it back to a < 1MB file as I would expect, are you able to attach the 3 page file that has such a large filesize?

@Jon, (to avoid space-wasting), this .afpub is already in this thread (with no reaction of stokerg):

I've logged this for the developers as I can't see why when I delete pages from your file the file size is increasing if save with history is not enabled.

There is a blank history entry in this file which might be something, I've noticed tis gets created if you enable save with history, was this file previously saved with history?

The file's "mother"-.afpub had once for a short test many weeks ago "Save History..." activated. After this test the document got saved several times, both with "Save" and "Save As...".
On the day, when pages got deleted and saved as a different .afpub, the history had not been active.
