Moving this discussion to the Premiere Elements forum.
Premiere Elements 13/13.1 have content download located in the Online Folder...
Local Disc C
and in the Online Folder are the DVD Templates and Sound Effects Folders.
I have found that once deleted the Online Folder will regenerate in the same place from which it was deleted.
So, try it if you must, but I would discourage you from doing so.
Please explain what the Elements Organizer has to do with all this. Are you trying to get Sound Effects and Movie Menus into the
Elements Organizer Create Slideshow feature? Cannot do.
Please give more details and I will think about this some more. My first impression that you are targeting cannot do goals.
Add On..after the above was posted, I found some grammatical points that I corrected.
