What is a CTG file?

Ctg file extension has Canon Digital Camera Catalog file type, developed by Canon, which is associated with the "misc files" category.

These are catalog index files. They are created by Canon digital cameras. CTG files contain information that details how many photos are saved in each folder of the memory card you’re using (usually up to 99). You can find files with this extension in the CANONMSC directory. It is not advisable to open or edit these files. If the corresponding images are deleted from the memory card, the camera will also erase CTG files it created. CTG files require much less space than .JPG files because they don’t store any image information. 

To learn how you can open the given file, read the information below.
