Please replace the MSL C library with the one that supports FileIO, the libraries should have been placed under CodeWarrior installation folder. And usually user can find such information in Compiler Manual or Build Tools Reference Manual, which are also included in CodeWarrior folder.
For details, please reply the CodeWarrior version you are using, as well as the part number of your MCU or Processor. Thanks!
