File and Folder Numbers
Recorded images are assigned consecutive file numbers starting
with 0001 and ranging up to 9999, while folders are assigned
numbers starting with 100 and ranging up to 999. Up to 2,000
images can be saved into a single folder.
Continuous
Auto Reset
Images may be saved to a new folder when there is insufficient
free space even if the total number of images in a folder is less
than 2,000 because the following types of images are always
saved together into the same folder.
- Images from continuous shooting
- Self-timer images (custom)
Images cannot be played back when the folder numbers are
duplicated or image numbers are duplicated within folders.
Please refer to the Software Starter Guide for information
regarding folder structures or image types.
