Using https://doc.qt.io/qt-5/qstring.html#arg and https://doc.qt.io/qt-5/qtime.html#toString

Change the string to add whatever format you want from whatever time (current time) you want?
Though I actually suggest not adding it right at the end as that will destroy the .tm file type suffix, so better: Infos/info_some_timestamp.tm.

I did it like that but it didnt work. I get this error message

QString::arg: Argument missing: Sakla/info, 11052021-113822
QIODevice::write (QFile, "Sakla/info"): device not open

QDateTime now = QDateTime::currentDateTime();
 QString timestamp = now.toString(QLatin1String("ddMMyyyy-hhmmss"));
 QString filename=QString::fromLatin1("Sakla/info").arg(timestamp);
 QFile file(filename);
