d6: File Number Sequence
When a photograph is taken, the camera names the file by adding
one to the last file number used. This option controls whether file
numbering continues from the last number used when a new
folder is created, the memory card is formatted, or a new memory
card is inserted in the camera.

File Number Sequence
If the current folder is numbered 999 and contains either 999
photographs or a photograph numbered 9999, the shutter-release button
will be disabled and no further photographs can be taken. Choose [Reset]
for Custom Setting d6 ([File number sequence]) and then either format
the current memory card or insert a new memory card.
Option Description
On
(default)
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.
J Reset
Same 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.
