The difference of ‘save’ orders in Director

what about the difference of ‘save’, ‘save as’ and ‘save and compact’ in Director?

a lot of friends asked the question, why  the director have three save.What is the difference among them, I should  choice  which  one to save my file?

In fact, to answer this question we should be aware of Director’s file structure, a Director movie file mainly contains the   cast and the score.  cast include all the necessary original  resources, score is responsible for the control of the film’s broadcast process, so it  can be seen that cast is the largest contribution to  the file size and also has great influence of the overall performance of last movie .Multimedia developers will often consider the issue and Optimized  film.

SUCH AS, import graphics files and video files which have been optimized , but the situation we meet is more common to import a lot of resources, and in fact did not fully use, as well as import, in accordance many files be with import in the needs of developers , Is not in the need of a movie  play, cast members in the cast window of the location and sequence  is not on a  optimization state.

These are the developers need to be addressed.The first case, you can find unused members, and then delete it ; the second case it is necessary to use the following command ‘ save and compact’.
