In the Project Course Format, each section has its own folder. The folder is kept in Admin >> FIles of each course (not the Site Files). This folder holds the media files and resources that belong to the section (project/topic/theme). Initially, each section folder is named "section01"," section02"," section03" and so on. However, for moving and importing across the site, it is important that each folder have a unique name. You will be prompted to make a unique name.
