@Zeyad-Khaled
Use QFile to save any data to a file, type does not matter.

Depending on your intentions, maybe (or maybe not) wrap it in a QDataStream.

You use just about nothing which is Qt code, so you could equally go use the iostream/fstream library methods instead.

And why do you open a new thread even it's the same like here https://forum.qt.io/topic/132871 (and the deleted one from you before this)?

WHAT
Qt is one of the most documented frameworks I worked with. And I had to deliver in Object Pascal, Delphi, Python and Qt C++, among abominations like typescript/js/node.

@Zeyad-Khaled You already found QFile::write() - so why can't you pass the pointer and length to this function? Don't see what this has to do with Qt...
