G'day there Jim,

You have to set the root as high as you want users to be able to go.
Perhaps "D:\" in your case. To give them complete freedom pass in zero as
the root.

Unfortunately, that's the situation I was trying to avoid. I want
to set a 'default' folder for the majority of cases, but still allow
those who actually know what they're doing to navigate where they will.

A fair proportion of my users don't have a clue, so I need to set
the default to the most likely scenario. For those who know enough to
set up their systems individually, I need to allow them access to what
they want. This could well mean a network drive, or somewhere else on
their hard drive. Zero passed in could well be OK for them, but
meaningless to some of the others who are just barely literate, let
alone computer literate.

I'll just keep trying to hunt around I guess. Thanks anyway.

See ya
