'Save New Projects as Packages' on PC

Hello all, my director and I are having some issues sharing files between his Mac and my PC.

I’m new to SBPro, and haven’t found much on the subject, but essentially when I save a new file name or version, I am saving out an entire project directory. So, to be sure any and all updated panels and elements are included, I have been sending him the full project directory for each file.

He asked me to enable the ‘Save New Projects as Packages’ in Project Settings, but this does not seem to exist in the PC version.

So, is this the necessary process to share files? And if there are no changes to any of the drawings, or additional imagery imported etc, I can simply share the SBPro file, and not the entire directory?

Thanks for any help,
