Hmm,
I'm probably just coming late to the party.
But, you say:
"If an app can't write to its own directory, it must be installed on the
hard drive and not running from a removable device." <-- TRUE (unless
it's on a CD-ROM or the removable device is LOCKED)
of course the inverse isn't true:
"If an app can write to it's own directory, it must be running from a
removable device." <-- NOT TRUE
and I thought you wanted:
"I'd like to be able to determine if an app is running from a removable
drive."
Two different matters, I think. But, I'm sure I'm missing something.
Just a couple of posts which led to the mismatch between the thread name
and the current goal/possible solution. :)
Given that it seems to require an external and/or too much processing
time to find out if the drive is removable, one solution proposed by
Bill Vlahos and Paul Looney was to explore the possibility of making the
app behaved as self-contained as it can anywhere it's run, using the
OS-mandated folders only when necessary.
This approach takes care of apps running from removable drives, and
still accomodates apps running from CDs or installed on a system where
the app can't write to is own folder.
The only downside to self-contained apps is that there's no file-type
association present in the host system's registry, so documents must be
opened from within the app rather than double-clicked. But this factor
is independent of any method used to determine what type of drive it's
one; it's just an inherent part of being a portable app.
I know this approach won't win any friends at either Apple or Microsoft,
since both prefer to dictate where we put files. But aside from being
non-conformant, it would seem harmless and carries some benefit for the
user by allowing the same app to run well with the smallest footprint
possible on any machine it's run on - it would behave well when run from
a hard drive and be completely portable on removable drive.
