File No. Sequence
Choose how the camera names files.
• Off (default): File numbering is reset to 0001 when a new folder is
created, the memory card is formatted, or a new memory card is
inserted.
• On: File numbering continues from the last number used after a
new folder is created, the memory card is formatted, or a new
memory card is inserted. If a photograph is taken when the current folder contains a pho-
tograph numbered 9999, a new folder will be created and file numbering will begin again
from 0001.
• Reset: As for On, except that file numbering is reset to 0001 with the next photograph
taken (if the current folder already contains photographs, a new folder will be created).
File Numbering
If the current folder is numbered 999 and contains 999 photographs or a photograph numbered 9999,
the shutter release will be disabled. If File no. sequence is on, turn it off and format the memory card
or insert another memory card in the camera.
