When user does a drag and drop from their local File Explorer to the HTML5 browser only window running a published app on the server, how can we change the default folder for the "Save As" dialog from "> This PC > Downloads" to something like ">This PC > ImportExport(Z >Photos"? We have configured parallels to map drive (Z to a specific place that we want that parallels HTML5 browser client to upload files to and we really need that to be the default location for the "Save As" window when uploading files.
