Eye-Fi card: Where does it store data on Android? I'm developing an app that works in conjunction with an Eye-Fi card (Pro X2 - which I understand will work faster over a wi-fi connection to Android) Question is, Android has so many memory locactions, (internal: private to app and not user readable, "external" storage which can be the fixed internal storage or SD card) 

So I'm seeking the help of Eye-Fi users to discover WHERE the device stores its data, and also if a folder is selectable by user.

For example, if I create a folder on the internal fixed memory, would an Eye-Fi user be able to set up the device to send data to that folder? Or does Eye-Fi set it's own folder that the user cannot change, and if so, where is it?

Alas, I can't test it myself at present as I have an OLD camera that uses an XD card!! (Eye-Fi being SDHC)
According to this article you must be able to select the local location as well as remote service (which is default setting):


  Settings of the Eye-Fi card such as wireless network access, selecting
  upload location on local computer and configuring photo sharing sites
  is done through software called the Eye-Fi Center which is available
  for both Microsoft Windows and Mac OS X. Recently mobile access (in
  beta) has been added via a browser.
