Can't copy Directory from Windows system even after i give admin to my app

AmrCoder

Hello,
I create an app that takes a copy of a Directory on C drive windows system to another folder when I work with windows system I give my app admin using this way here.
i use this code to copy the folder with all it's content.
this function.

void MainWindow::copyPath(QString src, QString dst)
{
    QDir dir(src);
    if (! dir.exists())
        return;

    foreach (QString d, dir.entryList(QDir::Dirs | QDir::NoDotAndDotDot)) {
        QString dst_path = dst + QDir::separator() + d;
        dir.mkpath(dst_path);
        copyPath(src+ QDir::separator() + d, dst_path);
    }

    foreach (QString f, dir.entryList(QDir::Files)) {
        QFile::copy(src + QDir::separator() + f, dst + QDir::separator() + f);
    }
}

and in the button

copyPath("C:/Windows/System32/spp/store", "D:/copyfolder");

when i test on another folder on D drive it worked so what i can do so that i make my qt app copy the folder from the C drive.
Thanks in advance

don't use foreach (https://www.kdab.com/goodbye-q_foreach/)
Check that dst + QDir::separator() + f does not exist before copying
What does QFile::copy return?

AmrCoder

when i give it this path

C:/Windows/System32/spp/

it copy only one folder which is

C:/Windows/System32/spp/tokens

and the other folders not copied when i give it the path

C:/Windows/System32/spp/store

it can't path this condition

    QDir dir(src);
    if (! dir.exists())
        return;

it can't recognize directory

both dir.mkpath and QFile::copy return a bool. Could you check if they return true?

Try:

void MainWindow::copyPath(const QString& src, const QString& dst)
{
    QDir dir(src);
    if (! dir.exists())
        return;
QDir destDir(dst);
        if(!destDir.exists())
            destDir.mkpath(dst);
auto entryList = dir.entryList(QDir::Dirs | QDir::NoDotAndDotDot);
    for(QString d : qAsConst(entryList)) {
        Q_ASSUME(destDir.mkdir(d));
        copyPath(src+ QDir::separator() + d, dst + QDir::separator() + d);
    }
entryList = dir.entryList(QDir::Files);
    for (QString f: qAsConst(entryList)) {
        Q_ASSUME(QFile::copy(src + QDir::separator() + f, dst + QDir::separator() + f));
    }
}

sorry for the late reply, i test the function and the same problem i think the problem is in this folder type i don't know why also i tried to check by adding this in the copyPath function and it output YES i not exists.

    QDir dir(src);
    if (! dir.exists()) {
        qDebug() << "YES i not exists";
        return;
    }

the folder i want to copy here

copyPath("C:/Windows/System32/spp/store", newPath);
