Hi Joe,
Any color tables, etc would normally be in your download folder or in a directory that you chose to put them in, even in the default directory. Custom place files would also be in the directory of your choice. There are also 2 directories located in your "Users" folder that contain information. It is normally hidden and is called "Users/AppData/Roaming/GRLevel3_2" and "Users/AppData/Local/GRLevel3_2".
