Packing a project removes all the temporary (cache) files associated with a project. This includes things like thumbnail images. Packing can fix issues and reduces the amount of space used on your device. When a project is shared or uploaded to a cloud, these temporary files are not included in the upload which saves you bandwidth and space.
