YOGA6DORG SPARKLES PRODUCTION SUITE, can be used
on a Linux PC with Oracle VirtualBox on top. It is
a Debian GNU/Linux of the Sparky Linux kind configured
with extras according to our likes and with more
hints of use as at yoga6d.org/economy.htm EcoNomy
column, -- crystallised September 16, 2015. It is
a desire to keep together a bundle of wellwritten
tools and programming languages and such, while the
surroudning platform should be used for any high-
security demanding network operations. In the decades
to come, it will be other forms of such programs 
that dominate, but then it is good to have a
production suite one can get used to for 'perennial'
file work tasks, also professionally. 

In order to transfer such .ova files over the net,
which has several gigabytes in it, it is convenient
to do it by means of file chunks. These can be
generated by the inbuilt command 'split', in GNU/Linux,
but they can also be made by such a program as
Gnome FileSplit (however this is installable only
in some java-contexts, and the program as it stands
doesn't always start in all linuxes). 

Once you have got hold of the chunks, they can be 
merged by (such a program as jus mentioned or,
in Terminal) the following simple command -- -- 

cat sparkles.ova.0?? > sparklesnew.ova

This you do right after using a browser to put them
into a suitable folder, eg /home/YOURUSERNAME/Downloads
folder. You open a terminal and type     cd Downloads
and then type the command. {No need to go to administrator
mode here, in fact it's an advantage not to, because
VirtualBox like to have also its import files read/write 
friendly for the local user.}

In VirtualBox, there is a File menu (on top, usually), 
and in it, you can select Import Appliance. The word 
'Appliance' is a more general one than 'application'. 
In this case it means a whole platform, an OS of its 
own. The YOGA6DORG SPARKLES stuff of course comes with
Yoga6dorg G15 PMN programming language.

In addition you have LTFIRTH, so you can, with a
PC that is wired to a router or such, use FTP
to transfer files in between the various parts of
the PC--from within Sparkles to LTFIRTH and from
LTFIRTH to the surrounding PC, and back. You can
also under some circumstances use a browser inside
Sparkles to upload a file, but only if you think
through whether this is a trusted site and that it
has been simply programmed (eg with Perl) to allow
fundamental uploads (not depending on those too-often
and too-revolutionary javascript version updates).

It documents itself for those who are used to Linux.
For others, they need a brief intro to get goin'.
