Look files
Looks and Look groups are defined in rich text format files. There are two files for each Look, called MyLook.rtf and MyLook.def, where MyLook is the name of the Look. Each Look group is defined in a file called Default.ini.
It is important that you always use the Look Organizer to copy, move, and delete Looks and Look groups. Do not try do any of these tasks by copying, moving, or deleting the files using Windows Explorer, because this will cause a mismatch between the files and the settings in the Default.ini file.
