What is an ICG file?
File created by Image Comparer, a program used for finding duplicate or similar images on the hard drive; contains a list of images which comprise an image gallery; used for grouping images together so they can be compared together or against another gallery to identify similar or duplicate images.
Identifying duplicate images helps users reduce the amount of disk space taken up by personal digital photos.
