EyesToTheSkies- How portable are files that have been categorised in a particular program?

Hi EyeToTheSkies, ACDSee apparently allows the categorization to be written into the image as a way of transferring collections between computers. I suspect that each program will do things slightly differently and some catagorization data would be un-retrievable in moving between programs.

I do like the ease of categorizing that ACDSee provides, a great improvement over simply storing the images in different directories.
