Handy Features
File Numbering Methods
The image files will be numbered from 0001 to 9999 in the order the
images are taken, then saved in a folder. You can change how the file
number is assigned.
The file number wiii appear on your computer in this format:
INIG O001.JPG.
Under the [_1] tab, select [File
numbering], then press <_)>. The
available settings are described below.
Select the option, then press <_)>.
®_ [Continuous]: The file numbering continues in sequence even
after you replace the card or create a folder.
Even after you replace the card or create a new folder, the file
numbering continues in sequence up to 9999. This is convenient
when you want to save images numbered anywhere between 0001
to 9999 in multiple cards or folders into one folder in your personal
computer.
However, if the replacement card or existing folder already contains
images recorded previously, the file numbering of the new images
may continue from the file numbering of the existing images in the
card or folder. If you want to use continuous file numbering, use a
newly formatted card each time.
