Bug File size after delete pages - possible bug? (Foxit mobile PDF for iPad).

[Nozokyo]

Greetings.

This might be a bug...

When I delete one or more pages from a PDF document, then save the result, the file size is the same (or close to) the original.
I expected the file size to be much less after delting pages, especially with heavy graphics content!

Is this a bug, or do I need to perform some operation to flush /purge the deleted files from a chache or somethong?

Thanks,
Michael.
