Very nice that everyone thinks along, but here's a picture of my hard drive on private Mac, in which I can put all folders in any place I want, after which, when I turn on Mac again tomorrow, I still see them all in the same place. The same applies to other Macs in my studio (and small museum from Classic onwards). Finder settings (via the menu at the top left) are both set to 'None', of course. In the meantime I have transferred all files to other G5 today and continue to work happily from there as I have done since time immemorial. Don't think about this problem any further and thanks for all the effort. Thread can be closed.
