Size of .ppta file
I think this has been asked before (on the old forum) but I can't remember the answer.
It seems that that ppta file often has old media in it that is no longer being used - just taking up space. I have been testing various forms of video -- and now I have a ppta file that has a very large video that is no longer used but doesn't ever disappear no matter what I do. I have published, and saved the production (which I vaguely recall was the offered solution before -- no difference).
How do I purge this file of unused video?
P.S. Is there some way to search/access the old forum?
