will I do this FILE extern *fileptr in the main file

and the othe file where i want to use it will i just char *fileptr={0};

You probably have a common header file for your application - add the following line to it:

    extern FILE *fileptr;

All your source files will of course #include this common header file. In just one of your source files, you need to actually declare the object, initialising it as well if you like:

    FILE *fileptr = NULL;

The variable is now available to be used by all the source files that #include the header file. Of course, your sequence of execution needs to guarantee that the value of the variable is set correctly before any module reads it.
