Moving files from UWP storage to NAS

Question

I'm writing a TimeLapse photo app. It'll grab an image every 5 mins and store to local storage. Another timer will sweep these files onto a NAS when it's online.

The problem is I can't figure out how to authenticate to a network drive (Synology NAS):

StorageFolder localFolder = ApplicationData.Current.LocalFolder;

StorageFolder networkFolder = await StorageFolder.GetFolderFromPathAsync(@"\\192.168.1.8\DropZone");

Any pointers on how to authenticate to the UNC?

I couldn't find any documentation on authenticating GetFolderFromPathAsync
