File Naming; Nef (Raw) Recording - Nikon D5500 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
(0 243), "_DSC", followed by a four-digit number and a three-
letter extension (e.g., "DSC_0001.JPG"). The File naming option
is used to select three letters to replace the "DSC" portion of the
file name. For information on editing file names, see page 159.

Extensions
The following extensions are used: ".NEF" for NEF (RAW) images, ".JPG"
for JPEG images, ".MOV" for 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.
