On
When a new folder is created, the memory card formatted, or a new memory card
inserted in the camera, file numbering continues from the last number used or
from the largest file number in the current folder, whichever is higher. If a
photograph is taken when the current folder contains a photograph numbered
9999, a new folder will be created automatically and file numbering will begin
again from 0001.
Off
File numbering is reset to 0001 when a new folder is created, the memory card is
formatted, or a new memory card is inserted in the camera. Note that a new
folder is created automatically if a photograph is taken when the current folder
