On QFile::readAll()

[useryy2]

I have a code like this:

   
     QByteArray content= file->readAll();
     qDebug()<<"File size is "<<file->size();
     qDebug()<<"Array1 size is "<<content.size();

I got the result:
File size is 77274
Array size is 1543


I have also get this:

        
        file->write(reply->readAll());
        qDebug()<<"readAll() size is "<<reply->readAll().size();

The file content is normal, but readAll() size is 0

This why. I think readAll() will read all lines from the file and they should at least has similar size.
