What is a COF file?
Common Object File Format (COFF) executable file created by MPLAB IDE, an IDE used to program embedded applications for Microchip Technology's PIC and dsPIC microcontrollers; stores machine code and debugging information for the program.
COF files are created from the MPLINK linker component, which takes object .O files, library files, and a linker script to produce the executables. Two other files are created as well with the ".map" and ".hex" extensions.
NOTE: The COFF format is not unique to MPLAB IDE. However, MPLAB IDE uses the ".cof" extension for its COFF files. COFF files also use the .OUT extension.
