It's obvious that I didn't fully understand how to use BackupPC_ls and had
moved on to try other techniques. I had expected that one or the other would
have eventually led to having a GUI interface that no longer said Error:
Directory XXXXX is empty, but instead listed the files available to be
restored. Now that it seems that I'll be working at the command line
exclusively, I'm in the process of trying to understand the usage and options
of BackupPC_restore and BackupPC_zcat and expect that I'll have further
questions coming.
I appreciate your patience with one who, in this case at least, knows what he
doesn't know - even if he uses a word that he first learned in boot camp many
years ago to describe his ignorance.
Dave

I was always told that 'assume' makes an 'ass' out of 'u' and 'me'. :)
No, it isn't one chunk. It's the content of the whole file (and its
name very likely isn't 'Detector.so').

No need for anything like that. The files are not stored in chunks,
they're stored whole, but usually (hopefully) in a compressed form as
you've seen.

Well if you put it like that ... to repeat:

You could do worse than read the V4 documentation, particularly the
part which begins "Here is a more detailed discussion:". :)

You're very welcome. In these exchanges I often learn as much as - if
not more than - the person I'm helping.
