title: How to simulate USB drive to transfer data to app instead of writing it on physical storage
body: <p>The purpose is to handle data, for example output of camera on phone, and send it to app, instead of saving it on drive and then open in app. I can not do it, but camera allows to send photo to specific location, for example usb-drive, so I want to use it as starting point</p>
  <p>I'm looking for answers that would at least make it possible on any OS.
  If situation that I'm describing has more specific terminology, I'll would be glad to know it</p>
  <p>&quot;IceDrive&quot; app is perfect example</p>
