Thanks Darby for your response.
You are correct in that I do get a folder with the original elements such as jpegs, solids, footage, etc. But what I’m after are the layers that have been animated in the timeline, with expressions, movement, effects such as particles, etc. I don’t want to have to re-create layers in a new project that I have already created in an old project, if you get my drift. Thanks for your input.
