Opening a file located on host pc

Hi all,

Im in the final stages of a project and have hit a big glitch need your help! please

I have the arm evaluator 7t connected to a pc running metrowerks codewarrior.
I am trying to open a text file hosted on the pc hard drive

When i try and run my code in the emulator mode (armul) the code works fine the file is found and ll is well. However when i run the same code on the arm board it runs and says it cant find the file. The code in question is:-

CODE:

FILE *file_ptr;
        int address[2014], value[2014], i, j;
        file_ptr = fopen("M:\\Documents\\final project local\\book1.txt","rt");
        if (file_ptr !=NULL)
                {
                        printf("settings file found\n");
               
               
                        for (i = 0; i < 2014; i++)
                                {
                               
                                        fscanf(file_ptr,"%x",&address[i]);
                                               
                                }
               
                        fclose(file_ptr);
                                               
                }
                else
                printf("file not found\n");

}

any ideas??? thanks

M:\\Documents\\final project local\\book1.txt is a long enough address try
something shorter and without spaces in between

ex k:\\project\\test.txt
