Auto Reset
The file numbering restarts from 0001 each time the memory card
is reptaced or a new foJder is created.
Whenever the memory card is replaced or a new folder created, the file
numbenng starts from 0001. This is convenient if you want to organize
images according to memory cards or folders.
If the replacement memory card or existing folder already contains
images recorded previously, the file numbenng of the new images might
continue from the file numbenng of the existing images in the card or
folder. If you want to save images with the file numbenng starting from
0001, use a newly formatted memory card each time.
