I figured it out on my own. For anyone searching here's a solution.
[hcs/folder_list] outputs the entire pathname and includes hidden files.
[splitfilename] splits the directory from the file and outputs each.
[list fromsymbol] changes a symbol into a list of numbers. The number 46 is the preceding dot of hidden files.
[route 46] will catch all files starting with a dot. The right outlet outputs everything else.
[list tosymbol] will reassemble the file name into a symbol.
The rest of the code recombines the path with the reconstituted file name.
Voila! Hidden files are ignored. Is there a simpler solution?
