File could not be loaded due to size

[kvraman03]

Hi,
I was using the C program to upload a file, while this month the file was little bigger which is above 2 GB and the program was not able to detect that file, where when i split the file into two it can able to show that and uploading,
KIndly let me know any idea you have about this, and also let me know if any further information required??

In this code i am getting the warning File NOT AVAILABLE with 2 GB file in the upload path

fp = fopen64(text_path, "r"); /* fopen64() for open a 64-bits (or) large file */
/**-- warn if file is not present ---**/
if (fp == NULL) {
     printf("File:%s NOT AVAILABLE\n", text_path);
} else {
     /**--- else proceed with upload ----**/
     /** Let's check the header first **/
     head_check = get_head_info(text_path, db_files[ctr].date_pos, db_files[ctr].freq_pos, db_files[ctr].exp_date, db_files[ctr].exp_freq);
     switch (head_check) {
          case 0 : /** Mark as ok for upload**/
               printf("File :%s\tDate:%s\tFrq.:%s -> ", db_files[ctr].file_name, db_files[ctr].exp_date, db_files[ctr].exp_freq);
               if (normal_yn == 'S' || normal_yn == 's') {
                    mark = get_yes_no("OK to load :");
               } else {
                    mark = 1;
                    printf("\b\b\bOK to Load :-> Y\n");
               }

               if(mark == 1)
                    strcpy(db_files[ctr].upload_y_n, "Y");

               break;
