Sure, but it is useful? To have an empty file allow to the user to open
the same application (hops .... activity... :) ) outside the sugar
interface, but this can be done using the normal application launcher.

Actually I not use the extension. I make some test and the normal
desktop identify the right application to open it (I make some test only
using data that came from Write and Paint activity). If I need to add
the file extension I need to know if the extension associated with the
mime-type. Can you help me?

Actually I read the data only on the start of the module, but can read
it on demand. Only is not so fast because I need to scan all the file in
the datastore.

Ok, but is the only way that I find to able the user to get the other
metadata information. Any suggestion?
