      Description

      QFile can successfully open a file to write with a UNC path. QSaveFile cannot open the same file. For example:

          QString path = QString( "\\\\drive\\dir\\myfile.txt" );
          qDebug() << "path=" << path;
          QFile f2( path );
          if ( f2.open( QIODevice::WriteOnly | QIODevice::Truncate | QIODevice::Text ) )
          {
              qDebug() << "QFile ok";
          }
          else
          {
              qDebug() << "QFile f.error()=" << f2.error();
              qDebug() << "QFile f.errorString()=" << f2.errorString();
          }
      
          QSaveFile f( path );
          if ( f.open( QIODevice::WriteOnly | QIODevice::Truncate | QIODevice::Text ) )
          {
              qDebug() << "QSaveFile ok";
          }
          else
          {
              qDebug() << "QSaveFile f.error()=" << f.error();
              qDebug() << "QSaveFile f.errorString()=" << f.errorString();
          }
      
      

      Returns:

      path= "\\\\drive\\dir
      myfile.txt"
      QFile ok
      QSaveFile f.error()= 5
      QSaveFile f.errorString()= "The system cannot find the path specified."
