Where to put on windows an option file accessable for all users?

Hmm, did you try to write to it?  Its writeable to me from LC.  I set the
folder to the specialfolder path, and popped some data into a file and it
worked fine.  From my reading, that that is the folders purpose.

If you notice when you check the properties of the folder, the "read only"
is a greyed out (ok, blue'd out) box, not a check.  (DON'T change it!)
meaning the folder itself is read only so you can't change it,but is
actually writable.  If its checked, that sets the contents of the folder to
read only.
If the folder has been messed with, the only way to fix it is take the
check out (so that the contents are not read only) and then set the read
only attribute on the folder itself from the command line.

By default though, the folder is set up correctly to be writable.
