#include <sys/stat.h>

struct stat s;

_stat("MyFile.TXT", &s);

int size = s.st_size

It's not standard C, but most compilers support _stat() ...

From MSDN

#include <time.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>

void main( void )
{
   struct _stat buf;
   int result;

   /* Get data associated with "stat.c": */
   result = _stat( "stat.c", &buf );

   /* Check if statistics are valid: */
   if( result != 0 )
      perror( "Problem getting information" );
   else
   {
      /* Output some of the statistics: */
      printf( "File size     : %ld\n", buf.st_size );
      printf( "Drive         : %c:\n", buf.st_dev + 'A' );
      printf( "Time modified : %s", ctime( &buf.st_atime ) );
   }
}
