What do you mean by "i am getting always unknown character" ? – Amontillado

Answer 1

Try out << endl;

It's making flush, performance suffers, write '\n' instead or use putChar – Adalard

Answer 2

When you open the file:

data.open(QFile::Append | QFile::Text)

Houlberg

That fixes the issue. But how? – Extreme

Do NOT work if you are using pure QFile, F.E. QFile file(path); file.open(QIODevice::Append | QFile::Text); file.write("111111"); file.write("2222222");file.close(); out is on one! line. – Adalard

Answer 3

Very fast way using QFile::putChar :

file.putChar('\n');
