Very good with one exception (so far)

I sorted by path, but the root folders still mix with files in subfolders: file name "c:xray.pdf" will list between c:washington2014.jpg and c:year2014.pdf, because x falls between w and y in the alphabet. Id like to see my root files listed separately, as if a lack of subfolder is the same as a subfolder named ~, so root files are always listed before subfolders. In the same way, root files within the subfolders would list before files in the sub-subfolders, and so on.

(Sincere apologies for using DOS/Windows path terminology, c: is just easier than the Mac alternative.)
