What is a dsc file and how do I open a dsc file?
A DSC file contains information about photos taken with a Nikon digital camera. Such files are saved on the memory card along with the image files but do not contain any image data. DSC files may be hidden on the card since they are referenced by Nikon's digital camera software and not meant to be opened manually.
