Report A little help for a few days in Dreamweaver Posted September 16, 2011 You can safely ignore those. Those are hidden files within Mac OS that stores info about the files. If you notice those folders within any of my videos/courses, let me know? I usually strip them out of the zip files before I upload things. In the Dreamweaver PC files they are in every single folder. If I can ignore them, I will simply delete them and put all chapter videos into a single chapter folder vs. a chapter and part.
