@JKSH Good worked, but would somehow print this value without quotation marks and dots

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    //VAR
    QString rootDir = qApp->applicationDirPath();
    QString data = "/data";
    QDir mkDir;
    bool autostart = QDir(QDir::homePath()+"/.config/autostart").exists();
    QDir test(rootDir+data);
    QStringList testlist = test.entryList();
    QString testout = testlist.join("");
    qDebug() << testout;

    return 0;
}

QString testout = testlist.join("");

What are you trying to do with this line?

@Nathan-Miguel Quotation marks come from qDebug and are not part of the actual string...
You can verify this using std::cout instead of qDebug.

@JKSH I want to basically want to set to open a file inside the folder (for example a video) automatically even if I change the name, so I need this value to be without these dots

@Nathan-Miguel
Look, the "dots" aren't part of a file name, they are the . and the .. entries in the directory, The other two are filenames. You are choosing to print them out all touching each other (testlist.join("")). Clearly that has nothing to do with your "want to set to open a file inside the folder". You can access indvidual files via each element in entryList() or entryInfoList(), as you please.
