When naming your folders (and sub-folders), create names that show the most important info first (obviously from your example: "PPHG MC"). Then follow it with the second most important criteria (yyyy_mm). Be consistent with the naming convention, and it will be a snap to find what you are looking for. (Do the same for all files contained within the "yyyy_mm" sub-folders.)
