If you setFileName() to a new file, prior error code is retained, which can cause operations on the new file name to fail when they should not.
{
// Create and close "foo"
QFile file1("foo");
file1.open(QIODevice::WriteOnly);
file1.close();
// Open "bar"
file1.setFileName("bar");
file1.open(QIODevice::WriteOnly);
// Try to remove "bar", fails (as it should, because file1 has it open)
QFile file2("bar");
assert(!file2.remove()); // Causes error code to be set within file2
// Try to remove "foo" (should succeed, because nobody has it open)
file2.setFileName("foo");
assert(file2.remove()); // Fails!!!
}
