Actually what I was looking for was to read the content of the entire drawing (which is not saved to a local disk) and be able to send it to a remote location using streams. The case is a remote file that is loaded to the Temporal Internet Files folder and then open, the file displays its remote location on the windows title bar. You can not save the document on this location without changing the windows title information of the drawing, and I wanted to save it back to its remote location.
