Once I have completed a video, is there any special way to save my video on the computer that will allow me to move around source pics and files used in the video (to clean up my computer) without having them deleted from the video?
You can move pds, videos and images to any where you want and when you will oppen the "pds" file PowerDirector will ask you to browse the file .. select every file and you have updated your pds file with the new files location.
