I want to enable user drag & drop folders onto a listbox based on this example (https://www.c-sharpcorner.com/UploadFile/6d1860/implementing-file-drag-drop-in-your-windows-10-uwp-applica/).
But it seems the dropped folder has Attributes set to ReadOnly. That's not what I expected because I need to delete files inside dropped folders.
Is there anyway to configure drag & drop so that it produces writable folders?

2024-04-10T11:01:14.3366667+00:00 UWP is toooo restricted in some way (that may be the main reason it fails). Think of FolderPicker, it returns a normal StorageFolder which I can use to create/delete files in it; even more I can add the folder to FutureAccessList so that next time the user restarts my app he/she does not need to do it again.
