    I think better QString::remove() should be used. Based either on previously found index of extension begin or on regexp it will be more flexible for further changes.

    @Denis that cant really be used sometimes i think. If you dont now the extension of the file, its quite ugly to find the extension in a string because of many special cases like differnt length or ".tar.gz" with several "." . So just taking this method save a lot of pain in my opinion

    QFileInfo does probably exactly what Denis said. However, since someone else did the effort for you, there is absolutely no reason not to use QFileInfo.
