Try:

FILE *source, *target;
int i;
source = fopen("Source", "rb"); 

if( source == NULL ) { printf("Press any key to exit...\n");} //exit(EXIT_FAILURE); 

fseek(source, 0, SEEK_END);
int length = ftell(source);

fseek(source, 0, SEEK_SET);
target = fopen("Destination", "wb"); 

if( target == NULL ) { fclose(source); } //exit(EXIT_FAILURE);

for(i = 0; i < length; i++){
    fputc(fgetc(source), target);
}

printf("File copied successfully.\n"); 
fclose(source); 
fclose(target);
