You didn't include a "Both" option, John. I don't have many 'projects' per se, with many files. I do have separate folders for plain Acad, Civil 3D, & Land Desktop tools. But, within each of those folders are a multitude of files, most of which don't rely on any others. Now, if I were still actually coding in lisp and creating Dialogs, I would likely go with the folder per project option.
