Using the Project tab, you may organize multiple file types into custom-named groupings.
A project contains pointers (or references) to the files that are saved on the specific My Files pages (e.g., structures, scripts, etc.), so modifying a file affects any project(s) that point to it.
Files such as structures, scripts, and sequences can be used/shared in multiple projects. Transcripts are the exception and can only be associate with one project at any one time.
