The EXIF data for my Canon shows a serial number at the very bottom showing the total number of shutter actuations. The numbering system "rolls over" after a certain number (usually 10,000 -- so they can use four-digit numbering), and then the next number increments and your folder numbers change.
Beware though, if you use a "borrowed" memory card formatted in another camera, it can reset the numbering -- I'm not really at 29,000 exposures ...
