Sure.
Well I made this:
Qt Code: 
  1. #include <QtCore/QCoreApplication>
  2. #include <QFile>
  3. #include <QDebug>
  4.  
  5. int main(int argc, char *argv[])
  6. {
  7.     QCoreApplication a(argc, argv);
  8.  
  9.     QFile f("C:\\Program Files (x86)\\TeamViewer\\Version6\\TeamViewer.exe");
  10.         if( !f.exists() )
  11.  
  12.              {
  13.               // It does not exist
  14.                qDebug() << "The file does not exist.\n";
  15.              }
  16.  
  17.             // It exists, open it
  18.              if(!f.open(QIODevice::ReadOnly))
  19.              {
  20.               // It could not open
  21.                qDebug() << "Failed to open.";
  22.  
  23.                return 0;
  24.              }
  25.  
  26.             // It opened, now we need to close it
  27.              qDebug() << "Success";
  28.  
  29.              int size = f.size();
  30.              qDebug() << "size: " << size;
  31.  
  32.             QDataStream data(&f);
  33.             char * buffer;
  34.             uint u = sizeof(f);
  35.             data.readBytes(buffer,u);
  36.  
  37.  
  38.              f.close();
  39.              return a.exec();
  40. }

Then I thought that I may need to make a loop,in order to read a byte after byte..but still nothing.
