I want to build a platform independent file copying tool using qt and need to modify file parameters like creation time and so on.

Any ideas?

QT has no special way to do that (you will find that all methods of QFile and QFileInf that deal with times are 'const'), but 'utime()' is POSIX and therefore portable anyway (see e.g. the related discussion at http://lists.trolltech.com/qt-interest/2005-03/msg01350.html#msg01350 - also the original source of 'touch' in http://ftp.gnu.org/gnu/coreutils/coreutils-5.0.tar.gz), so you basically could
/* UTIME.C: This program uses _utime to set the
 * file-modification time to the current time.
 */
 
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#ifdef WIN32
#include <sys/utime.h>
#define SHOWCMD "dir utime.c"
#else
#define _utime utime
#define _utimbuf utimbuf
#include <utime.h>
#define SHOWCMD "ls -l utime.c"
#endif
 
void main( void )
{
   /* Show file time before and after. */
   system( SHOWCMD );
   if( _utime( "utime.c", NULL ) == -1 )
      perror( "_utime failed\n" );
   else
      printf( "File time modified\n" );
   system( SHOWCMD );
}
