About Self-Contained Templates and Styles
A template or style can use a surprising number of assets. Motion backgrounds and assets
assigned to the button thumbnails can be very large files. In many cases, templates and
styles you create that use motion assets will be specific to a particular project. In these
cases, there is no reason to save them as self-contained.
If you are creating a template or style and want to be sure it will always have the assets
it requires, you can save it as self-contained. In this case, the assets are added to the
template or style’s file. This makes it possible to copy the file to a different system and
still have a working version of it. The drawback is that the file may be very large.
