Yes please. I raised this recently in a thread that died (but with no 
negative responses - see below). I started looking at the various 
modules to try to bring the whole thing together into a reasonable 
proposal, but it was just a can of worms (glob, fnmatch, pathlib, 
os.scandir, os.walk, os.fwalk, fts ...). I'm afraid I don't have the 
free cycles to try to tackle that, so I ducked out. It would be great if 
all of that could be somehow brought together into a cohesive filesystem 
module.
