Display of special files is not supported

hi. when i use Proc*C to develop my project. I need to create a file with the suffix PC, but I found that codeglanc doesn't support files with PC suffixes, and the side thumbnails don't show anything. In the same project, CPP and C files can display the abbreviation of code correctly. Other suffix format files seem to have the same problem, please check.
