Qt C++ remove a read only file in windows using

Question

I have set a file to be read-only (right click and check readonly). Now when I try to remove the file using the function bool QDir::remove(const QString & fileName) the file is not removed and false is returned.
How do I proceed with this? I have tried fiddling around by changing the permission of the file using QFile::setPermission, but that returns false too.
Can anybody advise an approach for the same?

Answer 1

file.setPermissions(QFile::ReadOther | QFile::WriteOther);
file.remove();

should work.

Answer 2

You can set file permissions with QFile

Of course this only for files you have user permission to do. The error may also be because the file is open in another app
