I believe I have solved the problem and would like to share it:
I needed to move an entire fairiy comlex project to an internal drive from my cloud drive. The size in totality of the entire project with 12 rendered and saved each as a project Video file in the .MOV format is over 29GB.
I packed the content saved in each of the 12 project files and saved them on my destination drive. So now I have 12 video project files in the packed format.
Then I was able to bring them into the Create module of Powerdirector individually or all of them..
Otherwise I could find no alternative of transferring an entire project made up of multiple video projects to a different drive and yet address each video project seperately.
Any flaws in this reasoning.
