Comment 7 for bug 1518332

To make a general statement, FileManager "open" functionality tries to export the content via content-hub, which will cause a copy of the content to be sent to the destination app and a copy to be made. A "view" operation should be supported as well that simply calls url-dispatcher with the correct url so the content can be viewed by the app but not copied. This should be done for pictures and videos that live under ~/Pictures, ~/Videos, or SD card to prevent copies.
