I'll attached the install script from /DK_System/install/install.sh
Here you see that the bottom part is remarked out, compared to yours. This is of course as it should be, as you are not unpacking anything.
I do hope that 'Mr.NiLuJe Wizard' or some of you other experts here may answer this a bit. AFAIK, if those visible parts is deleted, it would not attempt to start up anything. So, the worry here seem to be any evidence that one has tried to run something other then Amazon ?
It should be easy to use this script as guide for removing these named files. I don't think they cause any harm if present. They don't take up much space, - but in my view, the duokan system is not an entirely independent system. Which may be the real bonus here, as it may open the pandora's box. There are some computer games and other stuff you may download, it could seem like, but I don't read chinese.. so ..
I'll may add some comment here when I know a bit more about the content, or hopefully some of the experts jump in here.
!! Oh my god, they telnet some extraterrestial starships with those dangling files ! Duck, keep your heads down !
