Menu item details
Series:
The product will assign numbers to files sequentially up to "9999" without resetting.
Reset :
The product resets numbers when a file is recorded in a new folder and assigns numbers to files starting with "0001".
(When the recording folder contains a file, a number one higher than the largest number is assigned.)
Hint
The setting for [File Number] will be applied to both slot 1 and slot 2.
Even if you change the setting of [Prioritize Rec. Media], the file numbers will be sequential across the two memory cards in each
slot by setting [File Number] to [Series].
