Picture Counter reset

I searched around this forum and couldn't find a definite answer (some suggest starting a new folder and storing pictures there, others say download to another OS, and so on...)

Is there an easy way to reset the picture counter...you know when you take a pic it say : 20110826-00001 or something.....is there any way to reset to zero?

And yes the camera well reuse file names but I don't want to delete or move any of my pics....I know where they are, how far I have to scroll to get them etc etc..
