Re: ARCHIEVE, RESTORE and flag handling

ON (hold) F1 F6 wipes the calculator out to prepare
copying everything back over from the SD card.

ON+A+F (followed by NO) leaves you with empty Port 0 and HOME
(shortly re-populated with a CASDIR and a Hidden Directory)
and default flags; it does not clear ports 1-3.

I think the Port objects and library objects
are kept in their own directories on the SD card
to make things go quickly.

Is the entire backup segregated into a directory (folder)
of its own? That would be the only way to make multiple
independent backups, and also not to mix with any existing
set of SD "root" files.

One could conceive of making an independent program
to restore all the stuff, and perhaps ensure
that said program is itself automatically stored
(if not already present) in the root of the SD,
from where it could be executed, ending with RESTORE;
then the system could be said to be sort of complete,
for "cloning" calcs
(perhaps of interest in schools and libraries, as in
computer labs, where daily re-cloning freshens up computers
which are generally trashed every day by the users :)

For one-time copying, say of a 49G+ to a new 50G,
manual backup would seem about equal to the above-described effort
of manual restore, and is very easily done without an extra Filer
(which presumably backs up and restores itself?), especially
if using an empty SD card to begin with, so as not to worry
about spare parts left over at the end :)
