Possible windows bug in "QStandardPaths"?

Does this mean I always add a "/" - on all platforms - to paths - if I have to?
Dummy example:
QString myDesktopPath = QStandardPaths::writableLocation(QStandardPaths::DesktopLocation);
QString myWorkingDir = myDesktopPath + "/" + "Jobsfolder"
....
And how do I properly quote "Spaces" in paths than?

As written in QDir documentation, Qt always use internally '/' as path separator.
There are many help functions to work with path.
Your dummy example:

QString myDesktopPath = QStandardPaths::writableLocation(QStandardPaths::DesktopLocation);
QString myWorkingDir = QDir(myDesktopPath).filePath("Jobsfolder");

When you need to use the path for external "tools" (for example as parameter for a QProcess), you should use QDir:toNativeSeparators() so you don't have to carry about the path separator.

@KroMignon Thx for the perfect response I got it

QDir(myDesktopPath).filePath("Jobsfolder");

Last question about all this:

On Mac OS X app resources are in the bundle package "Resources" folder.
I would do QDir(QApplication::applicationDirPath()).filePath("../Resources"); than.

Be careful. I don't know anything about Mac or " in the bundle package "Resources" folder.". Is Resources a real, physical sub-directory located (one directory above?) your application directory, or is it purely an internal reference to the resources embedded in the executable?

I would do it like this:

QDir resourcesPath(QApplication::applicationDirPath());
resourcesPath.cd("../Resources");

// now you can use resourcesPath to get files from your resources directory.

@KroMignon thx again for this perfect answer

Ihm using this to get the appbundle path on Mac OS and the executable path on the other platforms

static const QString &ApplicationFolder (){
#ifdef Q_OS_MACOS
        auto getStringPath = []()->QString{
                CFURLRef url =(CFURLRef)CFAutorelease((CFURLRef)CFBundleCopyBundleURL(CFBundleGetMainBundle()));
                QDir d(QUrl::fromCFURL(url).path());
                d.cdUp();
                return  d.absolutePath();
        };
        static const QString path = getStringPath();
#else
        static const QString path = QCoreApplication::applicationDirPath();
#endif
        return  path;
    }

It is a real physical folder and may other things - defined by apple
Qt says: https://doc.qt.io/qt-5/macos-deployment.html

@J-Hilk thx for your suggestion.

I tried this way - because it is platform independent. On top using a QDir objects is giving lots of other handy functionality like .exists(); .remove(); .removeRecursively() and others.

QDir resourcesPath = QDir(QApplication::applicationDirPath());
#if defined Q_OS_MACX    
    resourcesPath.cd("../Resources");
#else
    resourcesPath.cd("resources");
#endif
