File names
File names take the form “DSC_nnnn.xxx”. nnnn is a number from 0001 to 9999. xxx is one of the following extensions, assigned according to the options selected for image quality and file type:
NEF: RAW photos
JPG: JPEG (fine, normal, or basic) photos
MOV: MOV videos
MP4: MP4 videos
NDF: Dust off reference data
Images created with [Adobe RGB] selected for [Color space] have file names of the form “_DSCnnnn.xxx”.
In each pair of photographs recorded at image-quality settings of RAW+JPEG, the RAW and JPEG images have the same file names but different extensions.
