Specifications

Folder name, file name
and file extension
You can create and select folders freely. The folder name format will be 100EOS1D, where
the first 3 numbers are based on the highest folder number existing o
n the memory card
that’s installed in the camera. The file name can be set to one of three formats:
1. Factory-default, four-character alphanumeric name
2. Any four characters (User setting 1)
3. Any three characters plus the image size (User setting 2)
If 3 is set and an M-RAW image is taken, the fourth character will be “M.” These three
settings also apply to the file name for videos. If Adobe RGB color space is set, the fourth
character will be “_” (underscore). For JPEG images, the file extension will be “.JPG.” For
RAW, M-RAW, and S-RAW, it is “.CR2,” and for videos, “.MOV.”
