Qt WinRT Folder Permission Issue

[haris123]

Hi I already posted a question https://forum.qt.io/topic/64442/qt-winrt-app-cannot-access-file-permission-denied regarding ffmpeg library and video file read, and now I think the entire project should have some permission to access/modify the files system in WinRt Qt App.

Below is a simple code which create a directory if not exist, bu this also failing always, so I think it permission issue, and there are something should add on AppxManifest.xml.

QString dirname = QDir::homePath()+"/test";
    QDir dir(dirname);
    if(!dir.exists())
    {
        //dir.mkdir(dirname);
        if(false==dir.mkpath(dirname)){
            qDebug()<<"Creating "<<dirname<<" failed...";
        }
    }

Anyone have faces this before, any suggestion, tips ..

Thanks in Advance.

hi haris,
at least you should use QStandardPaths::writableLocation instead of QDir::home. This returns for the related plattform the paths where the app is allowed to write.

I tried these too

QString dirname =  "C:/Users/haris/Videos/";

But still the error.

Hi haris,
this works on winrt:(at least in my project)

    QDir imagesFolder(QStandardPaths::writableLocation(QStandardPaths::AppDataLocation) + "/afolder/");
    if (!imagesFolder.exists())
        imagesFolder.mkpath(QStandardPaths::writableLocation(QStandardPaths::AppDataLocation) + "/afolder/");

as far as i remember it returns a path to user/AppData/Roaming/.... That is where since win8 (?) application data should be stored.
best,
patrik

Yes the above code works fine, but in my case I need to set path as user decide, it can be anywhere.
