What would be a "Modular Structure" in the After Effects Project?

I noticed that some projects in “AE” have written “Modular Structure”, what would this be within the project? It’s a way of naming files, organizing the project, does anyone have a video or tutorial that explains how it works? Or could someone explain quickly how to do this?


A modular structure is a way of organizing your project. It means that the templates is comprised of modules (comps or precomps) that can be edited individually. They can be customized, reordered, duplicated or deleted without affecting the whole project.

I don’t know of any tutorial showing exactly how to do that. I think everyone has it’s own way of making modular templates, however the concept is always the same.
