I've never heard of Dr Bunsen before, nor his file naming convention.  And yet, my hard drive and backup media are littered with files whose names look a lot like what he outlines.  I usually just use MMDDYY..descriptive name.ext, only adding .HHMM after the Date string if I know ahead of time I'll be keeping multiple files from that day.
While I can't say that it's been especially useful in locating any particular file I need, it does keep things in chronological order by default, and makes it easier to find reports from a given date.

And here I thought I was being all efficient in a unique naming scheme.  I should have know there's nothing new under the sun.
