So HoloLens is stupid in that it only recognizes one FilePicker at a time (no matter how many may be installed). I don't believe the developers are going to try making multiple filepickers work.

So, I'm trying to figure out my own filepicker in an attempt to be a proxy-select for other filepickers.

In essence, I want to make a filepicker chooser that appears as a typical filepicker (if that makes sense).

Trouble is, it doesn't appear possible to get a list of pickers installed!

Am I experiencing a pipe dream, or is there a way to invoke a picker from a list of pickers?

For the moment this is a pipe dream, but I sure hope they fix this. Per the Windows Holographic FAQ:

Note: HoloLens will always use the first app you've installed to handle file storage and this can't be changed. That means if you install Box and then OneDrive, all apps will use the Box file picker app.

  • But the question is, is it possible to obtain the list of available filepickers? – Tsaukpaetra Aug 12 '16 at 07:46
  • No, currently this is not exposed via an available api, that is why you always are forced to use the first one you installed regardless of how many you have installed. I would expect this functionality to show up at the OS level and not be available through public api's similar to Windows 10. – Cameron Vetter Aug 12 '16 at 19:39
  • Yeah, that was my point, that HL is supposedly running a build of Windows 10, are there apis to list filepickers on desktop Win10? I think probably not, but that's the point of the question: to ask if it exists and how to do it if it does. – Tsaukpaetra Aug 13 '16 at 02:11
