File Naming; Choose Image Area - Nikon Z 7 Reference Manual

File Naming

Photographs are saved using file names consisting of "DSC_" or,
in the case of images that use the Adobe RGB color space
(0 180), "_DSC", followed by a four-digit number and a three-
letter extension (e.g., "DSC_0001.JPG" or "_DSC0002.JPG"). The
File naming option is used to select three letters to replace the
"DSC" portion of the file name as described in "Text Entry"
(0 160).

Extensions
The following extensions are used: ".NEF" for NEF (RAW) images, ".TIF"
for TIFF (RGB) images, ".JPG" for JPEG images, ".MOV" for MOV movies,
".MP4" for MP4 movies, and ".NDF" for dust off reference data. In each
pair of photographs recorded at image-quality settings of NEF
(RAW)+JPEG, the NEF and JPEG images have the same file names but
different extensions.
