Hi,
I just want to know, is it the CCS software don't support the file I/O access ? Because I have
a program that worked well to access a txt file using c compiler but doesn't work when I use
the CCS. Thanks.

CCS supports file I/O.  You have to include the correct header files.

Files can be on the host and your DSP program can access them over JTAG emulator. 
However, CCS file I/O is very slow and you shouldn't mix that part of your DSP
program with real-time code.

How much effort / Googling are you doing on this?  Shouldn't be hard.  I tried:

  fopen include site:ti.com

and the answer is sitting there #1 hit.

Hi,
   
  This is the program that I run in CCS.  May I know what is the header file that I should
include in the program ? Thanks.

#include <stdio.h>    int main()  {      FILE *f;      char s[1000];       
f=fopen("infile","r");      if (!f)          return 1;      while
(fgets(s,1000,f)!=NULL)          printf("%s",s);      fclose(f);      return 0;  }

Regards,
