What episode did Barney show Andy his filing system on the Griffith show?

You're likely thinking of the episode "The Slutty Pumpkin" from the first season of How I Met Your Mother.

In that episode, Barney shows Ted, Marshall, and Lily his "slutty pumpkin" filing system, which categorizes women he's dated based on their "slutty pumpkin" status (a term he uses for women he's particularly interested in).

However, Barney doesn't show this system to Andy in that or any other episode.
