Or, if you have access to Visual C++
'File, New, Projects, Console Application, simple application'

And paste this to the .cpp file. This is a translation of the previous Visual Foxpro code, but this can correctly identify a file size over 2GB.

#include "stdafx.h"
#include <io.h>
#include <fcntl.h>

    short nheader, nrecsize;
    unsigned long nnewsize, nmaxrecords;
    __int64 ndbfsize;

    nretval = 0;

    if( (fh1 = _open( argv[1], _O_RDWR | _O_BINARY | _O_RANDOM )) == -1 ) {
      printf("Error opening File!\n");
      nretval = 1;
    }
    else {
      ndbfsize = _filelengthi64(fh1);
      if (ndbfsize > ntablelimit) {
        _lseek(fh1, 8L, SEEK_SET);
        _read(fh1, &nheader, 2);
        _read(fh1, &nrecsize, 2);
        nmaxrecords = (ntablelimit - nheader) / nrecsize;
        nnewsize = nmaxrecords * nrecsize + nheader;
        _chsize(fh1, nnewsize);
        _lseek(fh1, 4L, SEEK_SET);
        _write(fh1, &nnewsize, 4);
        _close(fh1);
      }
    }
    return nretval;
