Maybe not everyone is familiar with the 1D2 CFn8.
Brand new card, folder 100EOS1D, I see "0" in the viewfinder. After one shot, it now says 1. After 24 more shots, it says "25".
I now switch folders. The counter says "0" in the viewfinder again since there are 0 shots in the current folder.
I loved this as it allowed me to shoot quickly, and if I missed focus on a shot, glance at the number, and now I know which one to delete. I shoot 90 shots, and shots 34, 36, and 85 were OOF. I could do a quick review (which starts showing my #90), then scroll back to 85, delete (since the review is telling me 85/90), scroll back to 36 (display says 36/89) and delete, then scroll to 34 (34/88) and delete. I now have 87 good shots and can switch folders.
I used this A LOT. I can't seem to get the same functionality in my Mark IV.
