.CMP file

The .CMP file is one of the files embedded within a .CAM/.TRN/.TAC file. The CMP file has most of the basic data for the campaign. It is loaded by the campaign engine to show an overview of the file you have selected, so contains some information that is more correctly found in other files, but also copied into this file for convenience.
