Flatview folders only

is this the best way to show only the folders and subfolders in a directory.

SET flatview=mixed
SET HIDEFILTERFILENAME="*"

Edit: strangely this seems to break the filter box at the bottom where I normally type a key word in

Would this be more to your liking? It shows subfolders for each folder rather than in alpha order and omits files.

Set FLATVIEW=On,Grouped
Set HIDEFILTERFILENAME="*"

Set QUICKFILTERFLAGS=hidefiles
