Save As & Remove resources doesn't reduce file size

I removed all but one slide from my 700Mb project and did a SaveAs. I then removed all of the unused resources, leaving only 4 low-res images and saved again. The file is now 720Mb. What is causing this?

ActivePresenter Version: Pro Edition v7.5.8

OS: Win



You must shrink it after deleting unused resources to reduce the file size: ActivePresenter > Project > Shrink…


Wow - that’s a hidden feature. Thanks
