Huh. I had tried that, but it didn't work. Seems to be working now. Perhaps I typed something differently the first time.
Okay, thanks, that's great. I can now get individual files out.
I still don't know how to recapture my directory architecture though. The restored directory contains newroot, and that contains x_directory_problem and x_unknown, the former of which contains various directory architectures which I don't recognize, and which contain hardly any files.
My one file which I've now successfully found, for example. How do I find out where that belongs?
