Folder File
Capacity
Each folder usually contains up to 100 knages.
However, since images shot in continuous shooting and stitch assist
are always saved into the same folder, a folder may contain more than
100 images. The number of images may also exceed 100 if a folder
contains images copied from a computer or images shot with other
cameras. Please note, however, that the images in folders containing
2001 or more images cannot be played back in this camera.
