Hi Emilio,
Why don't you check if the volume or the folder does exists before
setting the defaultFolder property?
If there is a folder tFolder then set the defaultFolder to tFolder
else...
Should be reliable...
Check also the volumes property.

Hi all, here is an interesting one I thought I'd pass along to see
if anyone has encountered this before.
In the documentation for defaultFolder it says that if you set the
defaultFolder to a folder that can't be opened it returns "can't
open directory". So i have some code that mounts a volume from a
networked computer to move some files across the network. I
created a function to check if the network computer is, in fact,
mounted. The function works correctly when the drive is mounted in
that result() is empty. Now, to test my code, I unmounted the
volume through the Finder(eject) and disconnected the network cable
from the computer. But when I ran the code a second time, result()
still came back empty. That is, in the second attempt I set the
defaultFolder to /Volumes/MountedDrive/Folder/ when it should not
be possible, because there wasn't even a physical connection.
Whats interesting, is that i opened the console and listed the
drives available in /Volumes/ and sure enough "MountedDrive" was
listed despite the fact that it wasn't listed in the Finder. I
even rebooted with no network cable and "MountedDrive" still
appeared in /Volumes/.
So I tried one last thing, if the defaultFolder was truly set to
"MountedFolder" then my file moving code should work, right?
Wrong. That code threw an error and failed as you would expect
since there was no connection!
Does anyone know why this is? Is there some period of time that
old connections are retained in a lookup table b4 being removed?
I'd really like a solid mechanism to ensure that the drive is
mounted, and the above does not seem to provide that.
