Apple Logic Express 9 - Manual (Page 154)

When you create a new project (or use the Save function, in general), you can choose to
also save all associated files (assets).
Logic Express creates a project folder that contains the project file, along with separate
folders for files used in the project (audio files and so on).
Saving projects without assets minimizes the memory requirements for project storage,
allowing you to transport them easily to other Logic-based studios—either physically or
as email attachments. This also means that the project will not be able to load the
referenced audio and video files when moved, unless these other file types are also moved
(the project is saved with its assets, in other words).
Project folders help you to keep track of your work: they ensure that all files related to a
particular project are neatly saved in one location. This makes it easy to back up and
transfer projects between computers or disks, and helps to avoid embarrassing problems
such as missing audio files, or samples that you need to search for, or reconstruct, in the
studio.
