"CBM" is the "traditional" fallback, which some programs use to 
display "broken" filetypes (some values can be used in the directory which 
result in more or less random "types" in the "$" file, depending on the 
floppy rom used)

this is what i use:

typedef enum filetype {
  T_DEL = 0,
  T_SEQ,
  T_PRG,
  T_USR,
  T_REL,
  T_CBM,
  T_DIR,
  T_UNK
} FileType;

"VRP" btw is no commodore filetype at all, and could be something ide64 
specific indeed.
