On
The camera resets the file number to
100-0001 each time you insert a new
(unused) CF card. If you insert a card that
already contains some images,
numbering resumes from the next
available number.
Off
The camera remembers the last file
number, and starts numbering from the
next number when you insert a new CF
card.
Setting the File No. Reset to [Off] is useful
for avoiding file name duplication when
images are downloaded to a computer.
