Option Description
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 contains 999 photographs.
Reset
As for On, except that the next photograph taken is assigned
a file number by adding one to the largest file number in the
current folder. If the folder is empty, file numbering is reset to
0001.
