Update February 27, 2012: On this date, it seemed that "File Expert" changed
so that it did actually terminate when you select "Exit".
The persistent connection phenomenon could still be created by using
the "house" hotkey.
And, in fact, if you enter setup within "File Expert" and then leave
via the "house" hotkey,
it seems to leave "File Expert" running with no indicator in the Status Bar,
similar to the old behaviour.
That's not really as contrived as it sounds, either.
My hope when creating the page was that it would be a demo which people
could work through (on networks with appropriate permission, of course)
to demonstrate the phenomenon.
I had realized that the "File Expert" author would perhaps eventually fix the
arguable deficiency. But that seemed to actually happen only about a week
after I managed to get my photo session done. I didn't expect it to
happen so soon (that is, before I had the commentary ready). It was
still (February 28, 2012) the case that a running "File Expert" keeps
its SMB/CIFS/"samba" file server connections open longer that other
similar apps which appear to time them out relatively quickly.
In fact, however, when I was first made aware of the discrepancy between
intrusion detection logging and my actual actions, I had initially assumed
I must have used the "house" to exit the application, but was relieved
when I started experimenting to discover that "Exit" exhibited the
behaviour it did, since it seemed a more natural thing to have done.
March 7, 2012: An update on March 7 to the "File Expert" app seemed
to revert the behaviour, and "Exit" could be used to leave the
app running, and a connection open.
Change logs at
not note any changes regarding this behaviour.
One would expect them to have some incentive to avoid leaving persistent
One might also expect that they would not want to advertize whether they
leave persistent connections, or have ever done so.
It's also possible some of the changes in behaviour occur because of
operating systems changes and not changes to "File Expert" per se.
March 12, 2012: Another update to the "File Expert" app on March 12
seemed to leave things so "Exit" would leave a persisent connection.
March 24, 2012: Another update to the "File Expert" app on about
March 24 seemed to leave things so "Exit" would leave a persisent
connection. This, and the previous change, did not make it into
the change log until
And in the change log, it is implied this (currently) most recent change
happened on March 26, when it was in fact distributed via Google Play (sic)
some time near the end of the previous week.

No notice yet at Twitter
But over the weeked I discovered you can leave a persistent connection which
the server times out after twenty minutes by turning the phone off
while the connection is open.
That method even works for File Manager if done at just the right time. That suggests
Android 2.2 (at least) doesn't properly close such connections
for each task at shutdown.

This release was announced at
Twitter: https://twitter.com/#!/Filexpert, but it looks like
they may have stopped updating their on-site
Jul 30, 2012: Since my last update here, the "File Expert" app
seems to have progressed to version 4.2.6.
I have been busy with other things, but the couple of times I tried the demo
since then, I seemed to need to use
the "house" key to keep the connection open, using the "Settings" dodge
to make it less obvious the app was still running.
I didn't actually manage to get the "shutdown" phenomenon to work either.
It really does appear they have stopped updating their on-site
change log, which is
because the twitter feed https://twitter.com/#!/Filexpert,
gets cluttered with noise.
In fact, if all releases are logged there, it's not obvious where all the
